Last Friday I picked up a Mesa Mark IV combo and a PRS CE24 and I had a little leftover so I ordered a Fulltone OCD. Anyway it worked great and today I plugged my guitar straight in and I'm not getting any sound just a very loud buzzing noise. I tried different leads and then tried it on my old amp and it worked so I know its not my guitar or leads. What could this possibly be? I had it retubed when I bought it. I'm probably going to take it back to the shop tomorrow and see what they say.
damn everyone is getting mark iv's. thank god im selling mine i cant stand it.

blown speaker?
