I can tell a difference, the modded one has a better well, everything to it. I kinda want to buy one just for old times sake. Or maybe man up and go for a DS-2. But any who before I go off topic, I liked it.

best person to ask would be mike, he recently modded both his ds-1 and his sd-1.

BOSS DS-1 Distortion Mods By Keeley Effects The SEEING EYE MOD

These are the mods that we have come up with. Mostly they try to give the pedal a more high fidelity sound and make it a little more tube like by use on one LED in the clipping section instead of two (commonly seen as a mod). We use metal film caps available from www.digi-key.com

C1, C5, C12change to 0.1uF metal film (104) C2, C8, C9, C14 change to 1uF metal film (105) C7 220pf silver mica or monolithic

In the DS-Ultra mod we change C11 to a 0.047uF metal film or better and lower R13 to 2.4Kohm. As well as changing C3 and C13 to 0.1Uf metal film or better.

D5 change to 3mm red led (the power LED that we take out!) In the D-Ultra mod we switch in another LED in series with D4.

R39 20K R14 1.5K R35 2.4K if you change the power LED to a 5mm Yellow LED

Add 47pf cap across clipping diodes, see second picture little green dot in the center. 7/64 drill bit needed to drill out 3mm LED for the SEEING EYE PART!

1) Take out the clipping diodes
2) Put them in the bin
3) Then put the pedal in the bin too
4) Buy RAT2.

thanks for the help guys, actually mike, your mod is what i liked.
so i might try that out, and whoever gave me the link to mikes thread about his mod, thanks

oh, one more thing, how much do these mods usually cost?

Not all that much in parts, it's the time and effort that it takes.

mike, ive noticed that you make some pedals for people who ask
how much do you usually charge them?

It depends what you're after really, shoot me a PM if you're interested in having something built.
