i like Zim(&tacos) asked:
have a JCM 900 50w 4502 combo 2×12 and the front input jack is out. Very little signal coming through. The FX loop input in the rear of the head CRANKS though. All the tubes are lit up orange, preamp tubes included. HLP PLZ?
Cables are A-OK and my SG has a dirty vol. pot but thats about it. I can plug the rest of my rig into the fx loop and get a great sound thru my TS-9. I’ll try workin the 1/4″ in and out. thX!

Well, I think that sounds normal as far as the tubes go. If the fx input works, but you don’t get sound from the input jack…. and you’re sure its not the cable, not the guitar, and not the volume, and it is plugged in… and you still get some signal (intermittently? or just quiet?)… then it’s most likely a dirty input jack or a bad soldering joint.
You can try to fix it if its the first…. plug in and unplug the cable in the input jack a couple dozen times. Seriously. If its a dirty jack, that should fix it.
If that doesn’t fix it, it’s probably a bad soldering joint, you should have an amp tech take a look at it.
