In the past, I have always played tube heads with built-in spring reverb (Carvin X100b, Rivera KR100 to name a few). After switching to my Soldano Decatone for the last few months, I just couldn't bear not having reverb any longer so I went out this past weekend and bought a Boss RV-5 pedal. I use it last in my pedal chain but before the input to the amp. I can dial in a good reverb sound on the clean channel, and then as soon as I switch to a lead/distortion channel, the reverb sounds like complete butt. It's all "gongy" and rattly. It's like when you have a spring reverb amp and you move it around when the power is on - TIMES TEN. JONG GONG BANG SPRANG DING CRONG BONG... Is that normal? I mean, is that why they make effects loops? Is it always going to sound like crap when I put the pedal in front? Am I screwed with just about any reverb pedal?
