PEDAL MODS

ATTENTION:

IT'S RECENTLY COME TO MY ATTENTION THAT SOMEONE OUT THERE ON THE INTERNET IS SAYING THAT MY MODS ARE A COPY OF SOMEONE ELSE'S. 

ABSOLUTELY NOT TRUE!!!

I HAVE SPENT YEARS COMING UP WITH MY METHOD OF RE-VOICING TWO PEDALS, THE BOSS SD-1 AND THE BOSS DS-1. I HAVE NEVER COPIED OTHER 'MODDERS' AND ANYONE THAT SAYS SO IS A LIAR.

IF YOU'VE READ THIS ANYWHERE ON THE NET, PLEASE TELL ME WHERE AND, YOU BETCHA, THEY WILL BE HEARING FROM ME.

DTS Technical Service offers superb pedal mods for Boss SD-1™ and DS-1™ pedals for unsurpassed tone. Ibanez TS-9™ pedals can be modified to original TS-808 performance. All work is performed by Ron Burati, a Fender™ certified technician with 30 years of experience in music AND electronics. Please see users' comments at bottom of page.  I also perform mods on Boss MT-2, Vox, Dunlop Wahs, Vox V810 Valve Tone and a few others.

NOTE! If you already have a earlier DTS modded SD-1 or DS-1, get yours upgraded for $10 plus return shipping!

The Boss DS-1 'MB4.7' Mod

Boss DS-1 MB4.7

Rich harmonics

Goes from slight overdrive to huge bone crushing Marshall-like gronk and beyond into insane distortion with greatly enhanced dynamic response

Big low end

Better 'TONE' control than the original circuit. And the MB4.7 is more Strat friendly but still works great with humbuckers

Huge OUTPUT signal, even at low 'DIST' control settings

The evolution of the MB4.7

As popular as the MB2 mod was, I wasn't satisfied. I heard things in the sound that I thought needed more work. After considerable experimentation I was able to successfully alter the pedal's voicing. The results are way beyond my expectations. This pedal has turned out better  than I ever imagined a DS-1 could be.

MB2: The plain Marshall-In-A-Box Mod

The MB2 was basically my take on the Marshall-In-A-Box Mod, which is a huge improvement (when done correctly) over the original DS-1.

MB3: Tone, dynamics, harmonics

The original DS-1 tone circuit provides radical bass boost/treble cut going counter clockwise and treble boost/bass cut going clockwise with a scooped sound in the center. I found this to be not only extremely limiting, but there was not place on the sweep that sounded useful to me.

The MB3 and MB3A mods provide VERY dynamic, extremely responsive touch. Even at very high 'DIST' settings, light playing produces clean tones. The notes breath more, they aren't buried under a blanket of noise. This means that you can hear the guitar's harmonics at all playing levels. Without touching a knob on your guitar, pedal or amp, you can go clean to huge crushing distortion just by picking light or hard.

The MB3 mod changed the control to act as a simple 'brightness' control for rolling off the treble. I changed the rolloff frequency so that the mids are not lost when tryign to tone down the highs..

MB3A, This one goes to 11

With the MB3A mod, an additional amount of extreme distortion is available at the very top end of the DIST control's rotation. From 0 (CCW) to about 4 o'clock it works like earlier versions. The last 10% of the CW rotation puts you into full saturated distortion / fuzz land with wicked harmonics.

MB4: 

Better Tone Control for the Player

The MB4 mod effects the tone control and further improves its usefullness. 

MB4.7: Strat friendly tone ckt

The MB4.7 is a slight varient that is the result of getting feedback from other die-hard Strat players. This version is a simple shift of the tone control's cutoff frequency.

About these modifications: 

The clipping mods warm up the signal at the distortion point in the circuit by taking away the fizzy brittle high frequency noise that masks the musical content of the pedal's output. This is done by changing the resistors, diodes and capacitors used in the part of the circuit that produces distortion from a clean guitar signal. The pedal's noise source is completely eliminated. I figure that if you really want noise, you can just turn the tone and dist controls fully up. But even then, by eliminating the noise that masks them in the stock pedal, you will still hear the rich even-order harmonics from your instrument.

Next, the additional EQ mods move the cutoff frequency higher on the bass side of the tone control. This allows the brightness to be tapered without losing all the midrange harmonic definition of your guitar's tone.

With these changes the pedal becomes extremely versitile:

At low Distortion settings you get a tone sounding something like a small tweed amp being cranked. Setting the Tone up at the bright end provides a super quack.

Moving the Distortion level and backing down the Tone control gives you a great overdrive sound with a nice snappy transparent high end. 

Moving the Tone control below 12 o'clock softens up the treble and brings out wonderful midrange harmonics but without losing the midrange or bass response.

Maxing out the Distortion control still gives you an outrageous degree of distortion but with a new warm harmonic-rich voice. Your chords maintain musical definition and single note leads sore with a wonderful harmonic sustain.

About Boost

All of my modded the SD-1 and DS-1 pedals  provide a huge amount of signal gain  so that -- even at low DIST settings -- you're capable of a substantial boost for soloing or if you just like to slam your amp's input hard. Of course if you don't desire the boost, you can just run the level control lower.

Bottom line: It's like turning your normally cold gigging amp into a dimed out 18 Watt Marshall™ through a big 4-12 bottom. Please see User feedback

Boss SD-1 88C Mod

First there was the Super Overdrive™ 808A ... nice
Then there was the Super Overdrive™ 808B ... rave reviews
Now there's The 88C Mod

Boss SD-1 88C

Greatly improved  smoother  tube-like overdrive characteristics

Very warm tone, rich in even order harmonics

Better bass -- a much fuller low end

Huge boost -- more gain and plenty of output which is especially useful at lower drive settings.

Improved tone control for better midrange when taking off the edge

Check out the sound clips

My customers were thrilled with the DTS SD-1 808b mod. The once sterile sounding pedal was given a nice warm tube sound with plenty of sweet even-order harmonic distortion like a good overdrive pedal should provide. My clipping circuit using additional filtering produces a thick sound like a vacuum tube amp's back end.

But the more I personally used the SD-1 808b, the more my ears told me that the EQ in the low end wasn't the best it could be.
So another year of playing clubs and trial and error and . . . it turns out that it was worth it.

The 88C: Announcing the NEW super suped-up RE-modded Boss SD-1

It has everything that everyone liked about the 808b circuit but now I've opened up the bottom end more for a thick, warm fatness that puts this pedal into a class of its own.

For now, I'm going to continue to mod the SD-1. Which is a great deal because these pedals can be bought cheaply and modified for a very reasonable price yielding a pedal on a par with the best boutique overdrive pedals.

But there are enough new parts involved in this mod now that soon we will introduce my own overdrive pedal based on my mods to the SD-1.

My re-worked overdrive circuit has a more natural dynamic response and more natural sounding overdrive, especially at high drive settings. At lower drive settings, the pedal is similar to but exceeds the best Tube Screamer clones with its more natural openness.

There's much more output for kicking your amps input when running at lower drive settings. My circuit produces richer harmonic overtones that ring and sustain longer and allow the player to get that controlled feedback that most find so elusive. And at higher drive settings this pedal goes into overdrive stratosphere.

The bonus is that this great tone comes with Boss' reliable construction.

TS-9 Mod

I can bring your TS-9 up to its legendary predecessor's (the Ibanez TS-808) performance. My upgrade gives you the warmth and tube-like roundness that made the Tube Screamer the de facto standard in overdrive pedals. Depending on you exact TS-9, this mod sometimes requires a chip change. If so, I will socket the board, install a RC4558 and return your original chip to you.

Prices:
basic mod $30.00 plus $7.60 s&h
with chip change $42.00 plus $7.60 s&h

Hi Ron,
I love my new pedal!!  It is to use a contemporary term Sweeeeeeeet!! Thanks so much for taking the
time to chat with me.  It was very refreshing to talk with someone "in the know".  I have not had that
opportunity for a long time, probably since I was in music school in 1980 something.

I just got my [SD-1] pedal upgraded from an 808b to an 88c. The 88c is wonderful. I have told all my friends about this pedal. I love to play Blues and Rock. Add this pedal to your tube amp and you will be in heaven! I am ear to ear smiles the whole time I am playing.

I've been playing with this thing (i.e. DS-1 MB3A) most of the night and this morning (between brief naps with the Strat hanging from my neck like a... well, like a Strat hanging from my neck, if you get my drift), and I have to say that it's all it's cracked up to be and more. MUCH more. Man, this thing goes from sweet, creamery butter that just coasts along almost unnoticed, but when you kick up the level and the tone controls it unleashes a truly evil beast that snarls and growls like a BIG cat. You want a canine reference? It can purr like a kitten, yet yap like a chihuahua, and it can growl and bark like a pit bull if you want.

It's a really clean, smooth, distortion that can rachet up to a real growl or roar. I couldn't be happier with it. It's all I was hoping for and more. LOTS more. Good job, Ron. THANKS!

Of course, I have zero experience with the Boss DS-1, so I don't know how much of it is the DS-1 and how much is the MB-3A mod. Whatever it is, this is far and away the best-sounding distortion pedal I've EVER heard, PERIOD!

THANKS, RON! I'll use this one forever.

"HOT DAMN!!!!!!

I gotta tell ya Ron, I don't know how you did it but my SD-1 sound's fantastic!! Those harsh barky mid's are gone as well as that obnoxious fuzzy top. Great articulation. The "crunch factor" seem's to be underneath it all as opposed to that "buzz" that was on top of it all.

You're right about the sweet spot on the tone and drive settings. The tone is set at about 11:30 and the drive is at about 10:30. Oh yeah, the bass response is perfect too. 

The DS-1 is a rocking machine too, no doubt about it. Seem's to have some added midrange as opposed to stock, but not overly so. As with the SD-1, I like how the crunch factor on the DS-1 is underneath, and the "fuzzies" are gone!! I am very impressed with your work Ron, now it's just a matter of me tweaking it all in."

Well I finally got to give my Ron Burati modified wah-wah pedal a workout Satuday and let me tell you these mods made a discarded pedal in the back of my closet into something that "boo-teak" makers like Fulltone should be afraid of.

I've had this regular Dunlop R/I crybaby since about '89, back when it and the Morley were about the only wah out there. I played the crap out if for several years when gear was something I couldn't afford and knew nothing about subtleties of tone. After several years I quit using it much due to a scratchy pot, all the noise when it was turned off and just not playing much music that incorporated wah.

Then a couple of months back I started looking at wahs again on Musicians Friend (there are now hundreds of wahs) and saw the Dunlop "Fasel" wah. Said it came with the "Fasel" inductor as found in the original Vox wahs and this was the secret to vintage tone.

So Ron put in the Fasel, added a DPDT switch and rewired for true bypass, replaced the scratchy pot and cleaned it up..

I got to play it at practice Saturday and the difference in tone and voice are amazing. 1st, it's dead quite when not in use, no tone suck and no hiss. No big clicks when you stomp it on. And no scratchy pot. Operation is totally smooth.

I'm not real good at describing tone but it now has a very broad range. The lows are very throaty without being muddy and the highs are very articulate without being ice-picky. The range from full bass to full treble is very great but you can still get a very broad range by just working the sweet spot with very little movement.

Other vendors like Fulltone are selling these Fasel inductors for $30 just for the part. If you're handy with a soldering iron, I'm sure you could do it yourself. But if you want to breath life into your old pedal, talk to Ron.

Thanks again Ron.

BTW we did a little Voodoo Chile, Too Rolling Stoned, White Room... now all I need is a Marshall and a coil cord!

>Often you can find the DS-1 on sale at G-Mart for $39.99. It's a love it or hate it pedal. 

Ain't that the truth.

I didn't love it until I got one that our man TremoloKing had hot-rodded. Wowie zowie. It sorta picks up where my FD2 leaves off.

"Hi. The modded DS-1 came today and I LOVE it! Can I post a review of it for you on a web site somewhere? A lot of players would flip over this pedal. Thanks for doing great work."

-- Jordan S

"Our very own Tremoloking does a Boss DS1 mod. I just got mine about a week ago and would like to present a review here. 

Firstly, Ron is a heck of a great guy to work with and he really knows his stuff. But you probably already guessed that from his posts on TFF. 

I bought a brand new, modded DS1 directly from him (at a very reasonable price). I did not previously own a stock DS1. Nor have I ever owned or heard (other than online clips) various other modded DS1s (Keeley, analogman) So, this is just a review of the pedal on its own merits. 

My gear: Fender Tele with Kinman p'ups into a SFDR. I also use a Fulldrive 2 and a Crybaby. That's about it right now. I was looking for something to pick up where the FD2 left off and give me some true distortion. My band plays all original comedic rock and sometimes we need to spoof hard rock/metal type stuff. A Tele and Deluxe Reverb really isn't the thing for that but the DS1 got me in the ballpark. 

Ron's DS1 has got gobs of thick, lucious distortion in there. The tone control is extremely useful as well and it seems to interact nicely with the distortion control. I can dial in some warm, mellow stuff, edgy crunch, or singing violin leads. My amp is voiced with a mid heavy A channel so when I switch to that side it sounds like a TS9 on steroids. 

I bought it for the heavier distortion type stuff but the pedal also sounds very good rolled back a bit. It seems to cover overdrive territory very well. 

I've had other distortion stompboxes before and they seemed to be plagued by a nasty buzzing tone as you dial in more drive. This one isn't. The sound coming through is very pure. It still sounds like my Telecaster, only much nastier. The guitar shines through. 

Get yourself one.
"

My amp tech Ron Burati makes a modded DS-1 distortion that I think sounds great. I have one in my pedal board and I like it a lot.

"I like it A LOT better than the Reverend OD as a second pedal. It's very transparent.

"Hello Ron, I got the pedal today. I like the tone and the gain. It is nice and warm.

-- Ken C on his modded VOX Valvetone

------------------------------------------------------------------------------------------------------------

"The pedal is awesome! I loaned it to my friend to try a month ago and he won't give it back! I told him to get his own

-- Peter S on his DS-1 MB2

------------------------------------------------------------------------------------------------------------

"Hey there. I got the pedals today. Thanks again. I plugged the DS-1 through my Pro Reverb and it sounds great. I love how it can actually sound like a slightly dirty amp to a raging monster.  And yes, the bottom end is all there.
