Hi Everyone
I have a problem with my 601 combo.I got it used off ebay and Ive had it for a 2 months now.I played a loud drummer setting last nite and this strange vibrating metalic sound is comming from my amp when the speaker is in the combo cab,I plugged into my ext cab,changed speakers ...all the test and it only happens when the speaker is in the combo cab.So im turning the combo into a head and I want to unplug my reverb cause i never use it and I want to know if anything bad will happen if I just unplug the reverb from inside the amp head.And has anyone ever heard of this problem before..

First thing to check is the tubes - a metallic rattling is usually a microphonic tube, as tubes get worn pretty quick in loud combo amps. It's most likely a power tube (since those have a larger plate structure and heat up more), though it could be preamp as well (especially with long-plate 12AX7s).
Second would be pretty much anything in the amp that could rattle. Basically go through and tighten up all the screws. This sounds like a tube problem, though.
But neither of these answers address your question, which is whether or not it's OK to leave the reverb disconnected. I looked over the schematic and the reverb appears to be solid state, so you should have no trouble there. Even with a tube reverb, I don't think there'd be a problem.
HOWEVER, why in God's name would you convert this amp into a head? You asked about disconnecting the reverb, which implies that you are either cutting down the cabinet or building a new one. If you're cutting down the cab, you're obliterating the resale on what was a $1500 amp. If you're building a new cab, that's ok. It begs the question, though, why wouldn't you just sell this amp and buy a head? You've only owned it 60 days, so there's no sentimentality. Just clean it up, sell it, and buy a nice pre-made head!

Well to tell ya the truth I only bought the amp for the clean ch. I dont like the distortion from the amp, Its just not that good for me. I use some nice distortion/od pedals. I put new power tubes in and no luck. I never thought preamp tube. Ill check it out....I like the idea of a small compact 60 watt tube amp head that weighs 32 lbs...
