looking for advice with Neovibe components

[sammy]

Hi everyone,
Sorry for the dumb ass question, but I’m still learning and I'm not sure about component substitution

I ordered a PCB for a NeoVibe from General Guitar Gadgets and I'm in the process of sourcing the components.

The schematics mention a DB102 Bridge Rectifier, but I can only get hold of a DB104. I assume for what I'm doing that shouldn’t matter?

Also, I can only get 2N3904 trannies instead of 2n5088 ones.
I assume substituting all the 35088's for 3904's shouldn't matter either?

Your advice would be appreciated
Thanks in advance
Sam

Any four-pin rectifier bridge that will fit in the holes on the PCB will work there. The DB104 I looked at will. Be sure to get it the right way round in the holes.

That will certainly work. The only place where it may be dicey is for Q11 and Q12, in the LFO. These need to be a certain maximum gain. However, I have built these out of all 2N3904s and had them work fine.

As a final bit of advice, go join the diystompboxes.com forum. There is a regular and ongoing discussion of building effects there, including regular requests from neovibe builders. I (and I laid out the neovibe PCB for GGG) go there more regularly than I check here. And there's a lot of history for such questions.
