Boss CS-1 Momentary to On/Off LED mod?

[zoki]

Hey Folks!  Been looking all over the web and these forums for a mod I read about but can't find anywhere - found the unity gain mod which is great but would love to have the LED stay on when the circuit is engaged.  Any help is greatly appreciated : )

Component numbers below are for the DS-1 ET-28 C/D circuit board. The component numbers for CS-1 are different (Q4=Q6 for example).
The factory mod is as follows:
1. Reroute the blue lead from the LED to the collector of Q4
2. Replace C22, 1/50 or 0.47/50 with .01uf mylar capacitor
3. Replace C18 and C19 ,470pf with 220pf.

I have some gut shots of a modded CS-1 if that would be helpful LMK

Fantastic - that's just what I'm looking for!  Thanks Ironman, I think that's enough to get me rolling in the right direction but I'll reply again here if I get hung up.

New guy here with the same exact pedal and want to do the same exact mod!  Would definitely appreciate a gut shot of your modded CS-1 so I can get the LED to stay on when the pedal is engaged!

Thanks!

Hey Dr. Jimmy,

I haven't done the mod yet - was working on the pedal for a friend and did a unity gain mod and gave him back the pedal to spend some time with - will post pics though if I get my hands back on the pedal for the mod!
