Devi Ever Electric Brown
Here's a unique little circuit from Devi. Plenty of gain on tap to go from just a boost, to an overdrive, to fuzzy the more your turn up the volume control. The Pregain control acts more like a tone control, panning between 2 capacitors. The first transistor stage is kind of like an Electra Distortion, and then I don't quite understand the 2nd transistor, but it works and it sounds good.
verified!
ReplyDeletei suppose emitter of upper transistor should be connected to ground... am i right?
ReplyDeleteI would have thought that too, but from what I can tell, it's not.
DeleteThis producing tone-sound richer than Purple Plexi 800.
ReplyDeleteAnd your PCB layout was perfectly good!
This beauty grounding reduce noise very much!
Thank's Bro
pregain 2 to in???? wheres in
ReplyDeleteis 2 in
DeleteVolume 1 and volume 3 are changed no? That way the pot will work reversed. In fact I have built this one and at least for me it was reversed. Also, the pregain is really giving you more gain - not sure how or why. Maybe it is changing the input inpedance?
ReplyDeleteIn my version the pregain also works reversed. Did I make a mistake?
Check out the General Layout Notes tab for the correct numbering of pot lugs.
DeleteHi, thanks for this layout. Can I use a 2n5088?
ReplyDeleteIt'd probably be ok.
DeleteBc550c is ok,more gain.
DeleteMy doesnt even sound like overdrive, more like tone coloring boost but its not boosting to much...
