Fender RI Reverb mods

Fender

<<<<<<
I'm going to buy a stand-alone reverb unit soon, and was
wondering if anyone has any experience with any types. I played through
one of the Fender ('63?) Reissue Reverb tube units,
>>>>>>

I just reworked a couple of these.

Out of the box they are OK, and a fairly decent imitation of the original.

But, the tubes are cheapies and the overall sound isn't quite what a real
one sounds like.

Fortunately, you can swap out the tubes with NOS 12AT7, 12AX7 and 6K6GT.
That will make a huge difference in sound. You can also change the 250pf
cap on the volume board to 390pf or 470pf to open up the sound a bit more
and make it less brittle sounding.

The tubes will cost you about $25-$30. The cap is cheap, but you have to
open it up to solder in a new one.
