DS-1 Ultra Mod

Description
The Keeley Modded BOSS DS-1 Guitar Effect Offers the Finest in Marshall-Amp Tone-In-A-Box!!! Perfect for tones like AC/DC, VAN HALEN, STEVE VAI.

JUST TALKED WITH STEVE VAI at the NAMM Show this weekend (01/2005)! He told me that he still loves the couple of DS-Ultras he has!

* With the diode Toggle Switch you have the DS-ULTRA! Huge tube like tone, switch back and you have the classic Seeing Eye Mod (SEM) version of the pedal for high gain, tube like distortion!

* Extra mods to increase the distortion range at maximum settings.

* Mods to correct the bass response and give you a fuller, more powerful tone. Perfect for Strats now with this mod!

* Comes with Cool Knobs!

* Toggle Switch Up - Our Standard Seeing Eye Mod.

* Toggle Down - Adds another LED to the clipping circuit for a Large Fat Tone.

The Extra LED increases the volume output of the pedal a bit, great for using the DS-1 as a pre-amp to push the amp or to fine tune a low distortion sound on the unit. The way we engineer the mod, it has increased 2nd order harmonics and tube-like qualities.

I had the pleasure of working with Steve Vai and DAVE WEINER (thanks SO much, Sir!) recently. He sent me 2 Boss DS-1s to modify for him. Somehow he got his hands on my DS-1 and dug it. He sent me his pedals, and while working on them, and while listening to his Live in an Ultra World, I came up with another version. So, I now offer the DS-1 Ultra Mod, which are the exact specs of the pedal that Steve had me create for him. The Ultra has a similar feel to the Seeing Eye mod, but with some noticeable upgrades. It also has the added flexibility of going from SEM to ULTRA with just a switch!

Here is sample of the Guitar Tab for the third clip, Prestige Ibanez into a DS-1, transcribed by Jeffrey Adams...

From a customer the other day watching Steve Vai..."There's a GREAT shot of your DS-ULTRA pedal in his new DVD Live at the Astoria that he clicks on during "The Animal."..."





Warren Mendonsa's writes...

"I prefer the ultra mode because of the increased fatness and response. The increased level boost is way cool! I've got the level and tone knobs at 9 o'clock and the drive knob maxed. I made a clip of it through the clean channel of the Mark IV. The amp was fully clean and all the drive's from the pedal. The guitar was a stock MIA standard strat."

???How widespread are the users of the DS-Ultra pedal?!?!?! How much can you do with these pedals?!?!?!?

Check out this email!!!

Hi Robert....

.....I feel I've owed you an email for a while now. Wanted to write to tell you just how great the mods are on the BD and the DS... I used both pedals extensively on the Simon and Garfunkel tour (which was a great experience), and, of course, continue to use 'em on the playing I do here in New York. Both pedals sound fantastic. They simply could not sound better, and have become an integral part of my set-up. On any given gig, I can get 3 different overdrive sounds of total integrity. I set each pedal with just a mild amount of distortion (just slightly at, or over the minimum), and with a very slight boost in volume. Each produces its own beautiful sound. Then, when used together, I get 'sound 3,' which I love as well. And they are quiet enough to do this...! Just great results, always. And, perhaps most importantly, my guitar still sounds like my guitar... When I A/B sounds with the pedals 'on' vs. 'off,' all of the tone of my instrument is still present, with very high integrity... Try doing that with a stock pedal!!!...

.....Next, the other day in the mail, I received a surprise. Package from Keeley. Opened it to find a top of the line Java Boost inside. Can't quite figure this out, because it was addressed to me, but I didn't order it, 'tho I secretly have been 'coveting' this item. I've yet to plug it in, 'cause I don't know if it is really 'mine'.!....Was this a mistake, or a gift from a friend? ( I generally try to help out, and do favors for, my friends....and some of them will go out of their was to say 'thanks'....). So, what gives???...it is serial # JB483.....CV7003 OC44. Pls let me know.

....At any rate, getting ready for the next leg of the S&G tour. We start rehearsing in a month, and then play concerts throughout June and July. Hope you've been getting some clients from me. People are impressed with the mods, and I'm not shy about telling them all about Keeley, and pointing them in your direction.....gonna check through my stuff and see if there's anything I'd like you to work on for me before the start of the tour.....in the meantime, the Java Boost?!?!??! (I did call your place about this the other day.) Hope all is well there.....

Your friend,

Larry Saltzman
