Hey guys! I’m new to the forums, and the proud recent owner of my first EHX effect, a Cathedral stereo reverb. I’ve been very pleased with it, but there’s just one problem I can’t seem to fix. When I engage the pedal, I get a noticeable volume drop.

First, some info on how my chain is set up. I have two chains, one from my guitar to my amp, and another for the FX loop.

Guitar > tuner > wah > overdrive > phaser > noise gate > amp

FX loop: 10 band EQ > Cathedral > stereo out to amps FX loops (two amps)

Everything is wonderful except for the drop in volume when I engage the Cathedral. So far I’ve tried:

– Cathedral in the normal chain instead of the FX loop
– Running mono (on the specified mono input and output)
– Noise gate on/off
– FX loop at + and – decibel settings on amps’ rear panels
– FX loop mix turned up/down on both amps
– Every setting on the Cathedral in every mode turned up/down (wet/dry mix, damping, etc.)
– EQ on and off, and taken out of the chain completely (leaving the Cathedral as the only effect in the loop)
– Two different power supplies
– Different cables
– Less/more gain/volume/master on the amps

No matter what I tried, I always got a noticeable drop in volume when the Cathedral was engaged in any mode, and volume would immediately come back up when I switched it off. The effect itself still sounds great aside from that. The main issue I run into is that when I switch it back off, suddenly my amp is roaring loud again and it really ruins the flow of a song.

Any troubleshooting suggestions I may have missed? Is this a common problem? I’ve never had volume drop off with any of my other pedals, so this is my first time trying to troubleshoot the issue.
