I commonly do this between my Bongo (active) and my passive Jazz5 or the Peavey Fury. My amp has a passive/active switch on it (not sure what the gain cut is). My signal chain is my Line6 G50 -> Korg Pitchblack -> Sansamp Programmable BDI -> amp. If I push the active/passive button without muting, I get a slight pop. I can overcome this by having the wireless off during the change if I remember. But......I've found that the active/passive button is more or less signal change than I need. Not the best way to handle things. I can program the Sansamp for a higher level with the passive but the Jazz and Fury have different outputs and I don't have enough programs. Generally I can play with the volume pots but all this seems to be too much to mess with during an instrument change. I want to unplug/plug and play. I am thinking of adding a volume pedal to my board. Is this a good solution or no better than spinning the pots? What do you guys do in this type of situation?
