MUCH MORE TONE
Thanks for your purchase! I am sure you will be very pleased with the tone of your new
DS-ULTRA Distortion pedal. The Boss DS-1 has a very heavy metal timbre to start with.
The many modifications take it to a full metal jacket sound. Every component changed or
added is of the highest quality. Metal film resistors are used for a low noise floor; this is
really needed for a high gain pedal. You will notice your new Keeley modded DS-1 has a
lower noise level than a stock pedal! Metal film and poly capacitors are used in the coupling
sections to provide the true midrange and high frequency transparency your guitar tone
needs while increasing the bass response of the pedal. It goes without saying that the note
definition has been improved. The final result is a pedal that provides more gain and volume
while losing no note definition. Perfect for driving Marshall stacks and other high-powered
gear. This pedal has been modified to have asymmetrical clipping. This mod gives you 2nd
order harmonic distortion. This has a very musical
sound. At very high saturation levels it almost
becomes an octave type of sound effect.
Your pedal has been modified to have the Seeing Eye LED. There is an LED
located in the “O” of the word TONE. This LED is not just a visual effect. It is in
fact fun to watch but it is actually part of the secret weapon in our reworking of this pedal. The LED is part of the circuit
that clips the signal and gives it that full, distorted sound. You can see that as you play heavier the LED burns brighter,
providing more distortion. As the note fades the LED fades too. Play softly or roll back the volume control to clean up
your guitar signal and the LED won’t light or might barely come on.

Your unit has a MODE SWITCH. With the switch UP you have the Seeing Eye mode of operation. With the switch
DOWN you have the Ultra mode. The Ultra mode has an even fatter, more robust tone. This is designed to give you
the “Wall of Marshall Amplifiers” tone. This is perfect for beefing up a Strat or pushing an amp hard so that you get
more natural tube amp distortion. Recommended starting point: Try setting the Tone Control at about 10 o’clock and
the Level and Distortion controls at 12 o’clock noon. Most modern amps are a little bright sounding so this might
sound really good for a starting point. I have to admit, my favorite sound with this pedal is a crisp yet really heavy
sound driving a tube amp. To set it the way I prefer, turn the Tone Control to noon and then set the Distortion and
Level control to about 2-3 o’clock. Stand back and enjoy!

The entire Keeley team thanks you for your business. You’re keeping the good tones alive! If you like this product, there’s
more where it came from! Have you checked out some of our other modifications? The Boss BD-2 is one of the best OD
tones out there; it can give you a slight break-up or an all-out tonal assault, practically bordering on fuzz! Other popular
mods include our Ibanez TS-9 Mod Plus, the Vox Mello Wah, and the Boss DD-3, which gives you three delay tones:
digital (stock w/ improvements), moderate analog, and all-out analog, all while still remaining in the digital realm. But
we don’t stop there. Many guitarists have embraced the Keeley Compressor, which stands above all others in terms of
transparency, sound quality, and ease of use! Other custom pedals include the cleanest boost on the market, the Katana
Boost, the smartest fuzz available, the Fuzz Head, and our popular take on the classic Rangemaster, the Java Boost!
