Not a lot out there on this one, but stumbled across the schematic over on FSB. Apparently it's another Marshall-in-a-box type. Sounds pretty good. Should fit nicely in a 1590B. The 1uF and 2.2uF caps are tantalum in the original but eletrolytics could be used as well. Original 1S1588 clipping diodes could easily be replaced with 1N4148s if need be.
Hi! thanks for your amazing site, you´re the man! any replacements for 4580?
ReplyDeleteThe 4580 looks like another general purpose part. You should be able to try any dual op amp... 4558, TL072, and similar.
DeleteFrom what I'm reading, though, it looks like interwebz people think the 4580 is an improvement and sounds "smoother" or "more modern" than most common ICs.
Anybody else have any experience?
Thanks mate!
DeleteMark this one verified. I used a 4558 and 1n4148's.
ReplyDeleteCool. Thanks for verifying!

ReplyDeleteI made this pedal but I have little gain ... how can I increase it?
ReplyDeleteUse a higher value pot for the gain control. A250k is where I'd start.
