Overview

The Boss DS-1 has a very heavy metal timbre to start with. Keeley's many modifications take the distortion pedal 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 essential for a high-gain pedal.

The Keeley modded DS-1 distortion pedal has a lower noise level than the 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.

It goes without saying that the note definition has been improved. The final result is an awesome distortion pedal that provides more gain and volume while losing no note definition. Perfect for driving Marshall stacks and other high-powered gear. The DS-1 effect pedal has been modified to have asymmetrical clipping, which gives you second-order harmonic distortion. In addition to lending a very musical sound, the Boss distortion pedal produces an octave-type effect at very high saturation levels.

The Boss distortion 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's part of the circuit that clips the signal and gives it that full, distorted sound. The heavier you play, the brighter the LED illuminates, providing more distortion. The Extra LED increases the volume output of the pedal a bit, great for using the Boss DS-1 as a preamp to push the amp or to fine tune a low distortion sound on the DS-1 pedal.

The Boss DS-1 distortion pedal's 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.

This Boss distortion pedal has a mode switch to dictate the different tones you use. With the switch positioned up, you have the Seeing Eye operation mode. With the DS-1 distortion pedal's switch down you have the Ultra mode.

Fantastic Pedal

By Taylor

from Santee, Ca

Comments about Keeley Modded Boss DS-1 Ultra Distortion Guitar Effects Pedal:

This was my first guitar pedal, and must i say it was worth the investment. It offers a variety of tone mainly for modern rock, but still test out its range. It was an user friendly, very easy to use. It's light, and i take it everywhere when i know i'm going to play.

AMAZING Distortion

By tim

from saline, michigan

Comments about Keeley Modded Boss DS-1 Ultra Distortion Guitar Effects Pedal:

If you want to spend a little extra from the original boss DS-1, it is definately worth it to get this. Amazing distortion that can play any kind of rock or metal you want. It can give a nice crunch to your distortion which most other pedals or amps cant. There is almost no noise or feedback from this and if you have a good enough guitar you wont need a noise suppressor. So actually youll save money from other distortion pedals that usually require a noise suppressor to sound good. This is definately one of the best distortion pedals out there.

Crunchy

By PRK

from Los Angeles, CA

Comments about Keeley Modded Boss DS-1 Ultra Distortion Guitar Effects Pedal:

This pedal is really good for high gain classic or modern rock. You can't really get a clean tone in case that's what you were looking for. Chords sound really crunchy, overall sound quality is great. The metal zone by comparison has a distortion that sounds so over the top it's actually really lame, like it's only for death metal. The ds-1 is also great for both rhythm and lead, whereas the metal zone sounds really fizzy when playing single notes. Flexible tone control with a lot of treble, very high output.

steve vai owns one

By chet

Comments about Keeley Modded Boss DS-1 Ultra Distortion Guitar Effects Pedal:

Steve Vai first introduced me to the world of Keeley electronics. This DS1 is just amazing. I ran it through my Marshall half stack with a Les Paul or my Strat, you cannot go wrong but you need to make adjustments.

My first pedal

By Jameka McClearin

from Atlanta, Ga

Comments about Keeley Modded Boss DS-1 Ultra Distortion Guitar Effects Pedal:

This is the first guitar pedal that I purchased when I started on the guitar. It was very easy to use and the sound quality was great. I used this at all of our shows even to this day and I have had this pedal for about three years and its still going strong. It is very convenient because of the battery or plug option. It is an awesome pedal and a must have for all levels of experience.

DS-1 to perfection

By Christopher

from Paramount, California

Comments about Keeley Modded Boss DS-1 Ultra Distortion Guitar Effects Pedal:

The first pedal i ever bought was a DS-1 pedal. The second i played it you could fell the power it was capable of. The distortion it was capable of was crazy i didn't think you could improve on the pedal but i was wrong. This new modded version provides cleaner sound and sick distortion. The moment i got this pedal i gave away my old one to a friend and never looked back. So if i was you i would buy this pedal over any other.

Great Pedal

By Al Glenn

from Sherborn, MA

Comments about Keeley Modded Boss DS-1 Ultra Distortion Guitar Effects Pedal:

i have had several distortion pedals made by BOSS and each time i get a new model, it seems to just keep getting better. the only downside is that you cannot leave these plugged in when you arnt using them or the battery will die very quickly. but it is great if distortion is your thing and also can deliver a pretty nice bluesy sound if thats what your looking for
