I have a Hammond CV organ w/ Leslie 122 and I'd like to add a stomp box effects loop box. I'm not sure where to make the connections. I am including the preamplifier schematic and also a diagram of the rheostat expression pedal box. The preamp does have a high level input where I have already connected a Swichcraft 12A shorting jack for inputting at instrument level. I'm looking for ideas as to where to best place the loop connections and what if any circuit is necessary (I think its just a couple of ¼ jacks). Maybe after the volume pedal box (rheostat) but prior to the preamp input? Some have suggested taping into the tone control (seen on the schematic). Any suggestions?
