I have two Acoustic image amp/speaker system. One has one channel and the other has two. I want to send a signal from my bass into the first amp and then send that same signal slightly delayed into the second amp for a fatter sound. What delay pedal/device would be the best for this and what is the best way to connect it. Would sending the original and slightly delayed signal into the two channels on my two channel amp give the same effect as with using the two separate amps? Thanks for any info !!
