No I didn't move any wires. I bought a Boss ME-33 multieffect to run through the effects loop, and the effects are good but the tone just sounds off after using it the past couple weeks, and sometimes my Amp gain doesn't completely switch off when switching from the distorted channel to clean. I read on another site that the effects loop tube may be bad, since this controls the overall gain on the amp but I'm not sure.

Re: Crate VC6212 Amp
Yes the tube could be what is called microphonic. In other words it behaves like a mic and feeds some signal back into the amp. These are usually 12ax7 tubes and are not expensive. Start with replacing that tube.
Keep us posted.

You put the pedal where???? The guitar goes through the pedal. This is NOT to be used in an external effects loop of an amp. The signal levels are wrong as the effects loop is LINE LEVEL and the pedal is for instrument signal levels. Move the pedal to before the inout of your amp as it is designed to be used.
I had a Crate G120C XL COmbo amp that was only outputting very quietly. I checked all pots. They were operating as they should be. I checked the speakers outs, the footswitch and its connections and both guitar inputs ..all operational. Problem: turns out when you plug an effect into the effects loop, there is an internal switch that lets the rest of the circuitry know an effect is there and routs the correct internal signal to it. As soon as I plugged in a pedal, Voila!!!! Full volume was completely resorted, no problem at all. So at this point I can either limp along with a pedal in the loop that isn't even doing anything, or I can go inside and repair the switch OR bypass it (short it out) so the loop is no longer functional.
There are other situations that can cause the same symptoms, but this is what was happening in this particular case. Amp cost me $50, sold it for $225. Nice. Got me another one-- almost same low price.
Usually the loop in is used with an EXTERNAL effects module where the audio signal is "looped" out through the external effect module and then back to the power amp to drive the speaker in the cabinet. The LOOP IN jack would receive signal from the EFFECTS module OUT jack.
The source to go TO the effects module INPUT may come from a jack such as preamp out, or sometimes the same loop jack if it usess the TRS (Tip-Ring-Sleeve) connection method.
If you do not have an external effects module, all this is a moot point in your case.
150 watts should be easily handled by four Peavey speakers in the connection you described.. If the Peavey's are 8 ohms, then your total load was 8 ohms for the series/parallel arrangement which is well within the 2 ohm drive capability of the Crate according to specs.
I question if you really mean the speakers were in series? This requires a special cable to do this. Now if you mean they were "daisy chained" like the amp went to one speaker and another cable connected that speaker to another, then you REALLY had ALL speakers in parallel electrically which would be at the 2 ohm low limit of the amp... In either case, with only 1/4 of the 150 Watts to each, the speakers should NOT have been damaged. The amp MAY have been damaged. Try each speaker individually at a REASONABLE level to test.
If you plug into the effects loop out jack,OFTEN the connection to the internal power amp is broken so you might have to arrange a special cable as a wye to go back into the power amp as well as your external amp. In any case pwere ALL interconnected amps, etc from the same power source/receptacle for system safety.
This is a guess: I suspect the bypass switch on that effects loop jack is causing a problem. These jacks cause a lot of problems. The switch passes the signal through if there is no plug for an effects in the jack.
You can SOMETIMES tighten up the contact to restore the jack. You have to disassemble teh unit to get at it of course.
if the multitrack doesnt have built in effects you need to but an extrenal vocal effects processor that you can wire up to it. try lexicon products, they offer really good realistic vocal effects rack units.
