Could someone please advise how I connect up a chorus pedal and a footswitch for the overdrive on a Fender Rumble V500? Will my bass run into the chorus pedal, which then connects into the amp? with the overdrive footswitch separately connected up via send/return loop? (the overdrive is built in to the amp, not a seperate effects pedal) OR do I run both switches in sequence via the send/return loop? So how many leads will I require? I will be adding to the effects pedals - tuner, compressor, delay etc Bit naive, I know, but info I've read on-line so far is confusing.... Thanks !
