Hello Gentleman,

It does sound like a tube problem. Not just swapping the tubes but also make sure the tubes are sitting properly & no bent leads on the bottom of the tubes or broken pieces left in the socket. I must say that I have never had any luck sending a pedal to EHX’s repair depot. They do not seem to really do more than take your money & then send the pedal back. I would suggest finding someone local who can take a look at it. My Luthier fixed my micro synth that came back from EHX’s repair guys & they had soldered a lead to the wrong spot on the back of the pedal. My Luthier opened the thing up & spotted the problem immediately, which made me feel pretty stupid as I had spent money to get the thing fixed, which took several weeks to get back not working, then drove 2 hours to my Luthier’s shop to have him fix it in 5 minutes.

Glad to hear it. What you described is a very common problem that indicated the tube(s) is failing. Also, odd popping noises or noise that seems to swell & fade. Enjoy the pedal, it is one of my favorites & if you check on my youtube channel you can see my pedalboard with the English Muffin. Just do a search for Folkstone57. I’ll be adding some new ones soon now that my new pedalboard is almost finished.
