Wondering if someone knows the answer to this before I take everything apart for trial-and-error investigation. Signal chain is Boss tuner-->MXR compressor-->Empress para eq-->Strymon Mobius-->Keeley Caverns reverb/delay-->JHS Morning glory drive-->TC Electronics looper-->A/B switch-->amps. The Keeley is new to me. When I switch it on, it makes a hideous noise. If I switch on the Mobius, the noise stops. My assumption is that the Mobius does something in bypass mode that bothers the Keeley. The Mobius and other Strymon pedals have previously played nice with other reverb/delay pedals.
