Hiyas!

My rig (listed in my signature) has always worked wonderfully for my goofing around with surf rock. However I purchased a volume pedal to help attenuate a little (aka keep wife from killing me) when I experiment with my EQ and overdrive.

That said, now when I tap into the fender reverb, I get a high pitched hum, sort of like I get from my Strat when not using 2 pickups. It only does it with the Reverb"on".

Is this a dirty power thing or am I missing a fundamental rule of chaining pedals somewhere?

tuner->overdrive->EQ->volume pedal->reverb->amp->???-> profit!!!

HI

I am not real familiar with your setup, but I will offer my $.02. First, even reverb units built into amps will have some noise when cranked all the way. Also, reverb is best used after any tone shaping, and should be the last effect in the chain. I think most amps put them after the power section and before the speaker, or just prior to the power amp section. Many times when recording, reverb is added when mixing, and does not come from the amp at all.

I think you should try lowering the levels on your pedals that are before the reverb, I think you are overdriving the reverb unit input a bit. If this does no work, lower the level on the reverb.

Another issue could be a bad cable in there somewhere

I hope this helps

I think I fixed it, but not sure how. I disassembled the signal loop and plugged it all back in the same way. Its a head scratcher.

Sounds like a cable problem or dirty jack. If it is an older amp use contact cleaner in the jacks and work a plug in and out.
