Generally very happy with the 6165 Stereo Pan Pedal: Guitar > Input A on 6165. 6165 Outputs to 2 amps in pan mode. Both amps are grounded. One amp will hum loudly no matter what position the pedal is in. Thoughts? Possible solutions? Thanks!

Ground conflicts can happen even if two amps are plugged into the same ground. Ideally they should be plugged into the same outlet via a power strip/extension board, but even then the circuits may not play nicely together. So, the trick is to lift the ground on one amp and allow the other to do the job of being the noise and safety ground for both amps (which is made via the instrument jacks). Just make sure that if only one amp is in use that its individual connection to ground is reestablished. See this great video from Taylor guitars about this...

Ground lift (i.e., "cheater plug" for one of the amps) works perfectly. Thanks!
