Intro[Top]
Ever since I got my ds-1 I hated it. It quite frankly, sounded like crap. I became interested in the properties of circuit bending the DS-1 through guitar geek but found that many of them had broken links to sound samples and pictures that didn't work. I eventually found a post from Indyguitarist (website can be found here: http://www.indyguitarist.com/) with a picture of how to wire the bends permanently. This is a great first project as it is easy to do and simple to reverse.

Bends[Top]
There are about four different bends, but five are listed. This is because A seems to be exactly the same as E, but it has been listed as two different mods before so there may be a difference. The first thing you need to do is solder a wire to the 'base position'. This wire is where all the variations are soldered to (see reference diagram.)

Putting a mod on a switch[Top]
You will need an SPDT (I think an SPST may work also) to wire this up.

Simply wire the two wires that would usually connect to two matching terminals and leave one terminal open and there you go!

Sound clips[Top]
Sound clips of the mods can be found here, but I suggest trying them all yourself to find which works best with your setup. I personally like variation D which is installed on my DS-1 at the moment.
Variation A
Variation B
Variation C - Couldn't record a clip, it has a cool fading effect, but didn't hold the notes long enough to make a good recording with my setup
Variation D
Variation E

Conclusion[Top]
These mods are a lot of fun to play with, but for my kind of music they have limited use. Another problem they have is that when the distortion pot is all the way up and the mod is engaged, it tends to void the bypass somewhat and lets the signal leak through. In a future project, I will be making a bypass box loop so you could use that to get around this problem. I think these mods are best used for feedback at the end of a set where you can get down to the pedal and move the dist knob to give a really cool effect.
