Yup, doing that now. Update to come. Man I hope this works. Fingers crossed. lol :lol: :LOL:
 
No dice. Same result. Changed every tube in the MOD50 with tubes I know are good. I'm at a loss here.
 
Damn man only thought I have is fuses. even if they look good they can be bad sometimes. I have no other Ideas, Sorry man!!!!!! WOW !!!!!!
 
For those of you who are following this thread, I think I have it fixed now, sort of. I got the MOD50 and the M4 working now, but they don't play together the way they did before. Before I had to have the master on the M4 almost dimed to be level with the MOD50. Now it's at noon and does just fine. I think this may be attributed to swapping the cable between my cab and amp for a better speaker cable. Who knows though. Also, my A/B box would only give me weak signal out of A side and great signal out of B side. However, if I turned both A and B on together, I get a good signal out of both A or B. Very weird. I'll get that figured out some other time though to determine if the pedal has a shot jack or what.

Also, the tremendous buzz was attributed to a dimmer switch in my basement. Thank you Bruce Egnater for asking if I had a dimmer. Totally didn't even think of that.

I'm going to break everything down here in a bit and hook it all back up and make sure everything is still kosher. It friggin better be because I have a show tonight and I don't need anymore aggravation.
 
You can go out of the feed on the back of your GCX into an empty loop and out of that send use it as an A/B box. I use a 1/4 mono-2 1/4mono jacks and have 3 A/B/C for 3 amps on or off in any or all combinations. That gives you better control with the GCP.
 
That's not a bad idea. I'm still having issues with my MOD50 though, so I have to get that solved first. Last night I hooked everything up exactly how it was at home and the MOD50 gave a dead very low volume signal. M4 worked great though. I can't figure it out. Today I changed the loops on the GCX just to make sure that wasn't the issue and put the MOD50 through the loop I was using for the M4 and vice versa. The M4 still works and the MOD50 still doesn't. I'm going to try new cables later today just to be 100% positive it's not a cable (although I'm 99.999% positive at this point that it's not). Because the switching is working and the signal is getting to the M4, I know it's not the GCX. If new cables doesn't solve the problem then the only conclusion I can come to is a problem with the MOD50. What's weird is that I plug direct into the MOD50 and put a patch cable on the serial loop and it works fine. I've never done this much head scratching. lol
 
I would've had the back off the MOD50 by now...all that cable re-rigging gets really old...LOL

GL man!
 
I've already tried changing ALL the tubes. No luck there. It's just mind blowing to me.
 
Its like taking your car to the mechanic..."does this and makes this noise"....but not around the mechanic..... :lol: :LOL:

Using the GCX as a A/B switcher will eliminate the A/B box, thats one issue gone.

So head and cab work fine when Guitar->Head->Cab? but not going through the GCX with the M4. :confused:
 
Update. Took all cables out and replaced every cable that wasn't brand new. Now it's working, but it was working before off and on. I'm going to move it around the house and then take it to practice this week as well. If it works in all situations and locations, I'll equate everything to a temperamental cable. It is possible this is the issue because in my old rack I never unplugged the head at all. Now with the cables going to the head being moved around a lot, if there is a cable issue that was intermittent, this could have never showed up until now. We'll see....

get a rack case with the head in it like Brad (RareGuitar) had. would make it easier to set up and less wear and tear on cables. ^ space rack/head isnt all that large and will serve as protecting your head as well.
 
Ya know, it could also have been the fact that you never unplugged cables from the head that caused the problem. It's not uncommon for corrosion to form in jacks and inputs when a cable is physically connected for a long time. Humidity combines with dust to create a film on contacts that begins to corrode. Because the cable is not removed and pushed back in, the corrosion builds up. Passing an electric current, especially DC helps it along--galvanic corrosion. Don't know if that played any part in your troubles, but I see it frequently with some of the older equipment I deal with in my job. Contact cleaner sprayed in the jack and a cable inserted and removed several times usually breaks up the corrosion.
