Hey guys- I traded out a my Gibson GA 15 RV for a vintage Leslie and picked up another from someone local for $350. Both are in excellent shape. Have you guys played through these things? Not very pracitical (the wooden cabinet on both is HUGE) but they sound AWESOME. DEFINITELY NOT AT ALL like any pedal I've tried... Amazingly 3-D. The first one only has the rotating speaker on the bottom, and no tubes. The footswitch allows you to use the speaker from your amp cab or the Leslie. I hook this one up to my '57 Twin, and it sounds SO MUCH warmer....it will remain hooked up to the Twin permanently I think. The sound makes me melt. The other one is tube driven, with the power amp inside the cab and a giant footpedal with the preamp inside it. I think you have to plug directly into the pedal. Is there away to use the preamp from another amp with this Leslie? I think it's a model 147. It has the rotating tweeter horns on the top and the counter rotating woofer ont he bottom of the cabinet. Does anyone with experience with these know if I can set the footpedal to take a signal from another amp, and if so, how? Any info is greatly appreciated!
