1 DCBirdMan 2 weeks ago I know just enough to be dangerous... I freely admit. Last summer a friend built me something along the lines of the Rivera-era Champ II... 12 watts, maybe Princeton power. Solid state rectifier. It was built on a Vibro Champ chassis. Looks and sounds great although a few more tone tweaks are going to be made. It's going thru a C10R. So I was wondering if a Fender reverb circuit could be added (stuffed) on. Not much room left on this chassis. Would need a pan (would have to be short 10" one -- do they sound any good?) another tube.. (or is it two?) and a driver transformer-- I think those are little guys like a choke. If this were possible I would sacrifice the dogmeat master volume this thing has, no prob there. So why go thru all this when you can just stick a $75 used Holy Grail on top and have pretty good reverb..(although it gets pretty crashy past halfway up). Not sure, really -- I just like pushing the envelope with Tedious and Demented Projects, I think. I think the answer is no -- not enough room -- but still would like to know what the assembled Council of Experts thinks.
