I have a Line 6 Echo Park that I pretty much love. Its crazy versatile and just plain sounds good, does everything I want. The only problem is the buzz. Ideally I'd like to run my chain: bass -> Joyo OCD -> Boss ODB-3 -> Echo Park -> Zoom B3 -> amp but if I put the Line 6 before the B3 it buzzes enough to really bother me. Placed after the B3 its dead quiet but then I can't use it when using the looper on the B3. The Zoom has a noise gate built in but its mediocre at best and really chokes the signal. Any ideas or tips? Thanks.
