I'm in the middle of adding reverb right now on my CV. I have a MKIV unit from an M-3 that I'm putting right into the console. The amp is on a very small, square chassis. It has it's own power supply using a 6X4 rectifier and a 6GW8 triode/pentode two stage amp. I've modified the power supply to provide the B+ for my pre-amp in lieu of a tone cabinet. Now, I'm going to insert the reverb line into the signal stream just like the vibrato is. I'll use a swith to bypass the reverb completely when it's not wanted. The output of the first section of the preamp found at the vibrato line will feed both the vibrato line and reverb amp input. The output from the vibrato line and reverb amp will feed the input of the second section of the preamp. What I'm working on now is the impedances and signal levels for the reverb amp. I'll keep you all posted. As far as overdrive is concerned, I have a theory I'm going to try out once I have the reverb worked out. The input of the second preamp section is a 6J7 pentode connected in super triode configuration. I'm going to experiment with the voltage levels on the different grid elements to see if I can drive the stage into class B clipping while maintaining the same volume level. One thing George Hiatt was talking about is adding a little bit of "dirt" at lower gain levels. I think it can be done. I'll keep you posted on this one, too.

Anyone know how to add reverb to a Hammond BV connected to a Leslie 122?
The preamp isn't like a B3. Also, how can I make it overdrive a little more?
It has some growl but a little more would be nice.Thanks...
