boss SD1 help.

[s_mcsleazy]

so lately ive been helping my friend find a boss sd1 for modding. however, when i was looking through my storage. i found an sd1 circuit. however, it's missing the pots and the jacks. so i have 3 questions.

1. numbers at the top of the circuit. does anyone know where they go?
2. can it be converted to true bypass or should i keep it as buffered?
3. any mods anyone can suggest?

I don't move in pedal modding circles, but it seems to me that there is no clear answer to the general bypass question. Anything can be converted to true bypass. But buffers have important uses; however you may not like the result when they are helping preserve higher end, or you may not like it when direct bypass stops them doing that. It depends on your tastes and signal chain (eg wireless vs cabled).

The SD1 may have some specific issues that could benefit from direct bypass. But hopefully without clicking or other side effects.

You can easily simulate what a change to direct bypass will sound like, just by switching out the whole pedal (from the actual signal chain that will be used) .. assuming it's stock buffered bypass. So with a long cable to the amp if that's what you actually use. You could even add a simple switch to change from a simple straight direct bypass connection back to stock buffered bypass.
