For those of you with amps without reverb, and are unhappy with analog/digital version stomp box versions, check out the Little Kahuna by Billy Zoom, at www.BillyZoom.com. It is a nice, hand- wired piece of tube gear, with great reverb, and the best tremolo available. It costs a little more than Fender's 63 reissue reverb unit....but is better built, and sounds better.
I've had one for a week, and couldn't be happier.
