Just found out this existed, anyone got any info, gut shots or a schematic for it?

In one of the old folded metal cases from the first LPB-1s etc.

Part of my vintage Electro-Harmonix Curiosity  :)

It's likely the same as the reissue.  I provided them with a schematic of the vintage unit a while back.  I drew it out from my original unit.

Do you still have that schematic? I wouldn't mind a copy if you could provide it.

Just curiosity, don't think i'll be buying the reissue.

I don't see it at the moment.  I'll dig around and see if it pops up.

Thanks!

Ha, eat your heart out Smokey, had no idea the 386 was that early a chip, figured it was going to be a transistor based power amp.
