Keeley DS-1 Ultra Mod

ds-1

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 oradded is of the highest quality. Metal film resistors are used for a low noise floor; this isreally needed for a high gain pedal. You will notice your new Keeley modded DS-1 has alower noise level than a stock pedal! Metal film and poly capacitors are used in the couplingsections to provide the true midrange and high frequency transparency your guitar toneneeds while increasing the bass response of the pedal. It goes without saying that the notedefinition has been improved. The final result is a pedal that provides more gain and volumewhile 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 2ndorder harmonic distortion. This has a very musicalsound. At very high saturation levels it almostbecomes an octave type of sound effect.

Much More Tone

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 infact fun to watch but it is actually part of the secret weapon in our reworking of this pedal. The LED is part of the circuitthat 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 switchDOWN 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 getmore natural tube amp distortion. Recommended starting point: Try setting the Tone Control at about 10 o’ c lock andthe Level and Distortion controls at 12 o’ c lock noon. Most modern amps are a little bright sounding so this mightsound really good for a starting point. I have to admit, my favorite sound with this pedal is a crisp yet really heavysound driving a tube amp. To set it the way I prefer, turn the Tone Control to noon and then set the Distortion andLevel control to about 2-3 o’ c lock. Stand back and enjoy!
