I have problems with my feedback.

Guitar with mini humbuckers >bad monkey>artec true bypass noise gate>rg50tc with a delay in the EFX loop.

50 watts tube, master volume on about 5-6, channel volume on about 6 and gain set on around 4, EQ is all fairly middle ground, slightly boosted bass.

Usually I'll be standing no more than 3-4 ft from my amp, but if I walk across the opposite side of the room, I still get feedback. If I turn the volume completely down on the guitar, still get feedback. Mute all the strings, still get feedback. Power tubes have just been replaced.

Also, my amp on about half volume is around the same volume as the other guitarist's 75 watt solid state amp on the same volume setting, surely something is amiss there?

So my next thought is wax potting the humbuckers? Or shielding the cavities?

Tube amps are usually around twice as loud as SS amps of the same wattage, so that part of your inquiry is normal (What is your second guitarist doing with a 75W SS amp anyway?).

As for your immediate problem, shielding might help, but if you can't find a solution, just avoid those areas of the room where you're getting feedback and you should be okay. I'm sure someone else will be able to help you more than I can, though.

Tube elitism fail.


Sounds like your pickups are microphonic.

This is not right. I suspect you're talking about hum/buzz, not feedback.

Feedback is oscillation/screeching/howling. It's caused by the amplified sound from the amp re-entering the pickups, being amplified even more until it overshadows any new signal the strings are creating. If you turn the volume on the guitar completely down, there is no way for that to continue.

^I have nothing against SS amps, but IMO the higher wattage solid states don't sound very good at all, especially compared to their lower wattage versions.

what?

That makes about zero sense... Higher wattage=less clipping=better tone...

Trust me, I don't understand it either. It is definitely feedback, though. I have a feeling my pots might be slightly problematic; if I have the amp low and turn the volume down I get no sound, but occasionally if I turn the volume down on the guitar with the amp loud, I can still get a sound from the pickups. I think that problem is on this guitar, might be mistaken. I'll check that in a bit.

But yeah, if I turn my volume down completely, I still get a high pitched screeching howling sound, the only way to stop it is to start playing.

I agree, his tone makes me wanna cry.

There isn't anywhere else in the room where I don't have the problem, which is the problem. It happens no matter how far from the amp I am.

All the solid state amps I've heard (admittedly, there isn't much of a selection here) sound better in the lower watt (up to about 30) versions than the high wattage ones. I don't know about the reasons behind it, but it's a pattern I've seen (or heard, I guess).

EDIT: On topic, I think there's a ghost in TS's amp. You shouldn't be hearing feedback if your volume is at zero.

Look man, you need to stop this. This SS -vs- Tube bullshit has no business in a thread where a user is trying to debug a problem with his guitar/amp.

Consider that matter a closed issue in this thread.

Yeah, I'd have to guess there is something a bit flaky about the connection to the ground side of your volume pot.

There is a limit to how much gain you can use before any guitar will feedback. Maybe your pickups need potting in addition to you repairing the connections in your guitar and/or replacing the volume pot. But you might need to use less gain and more master volume.

Interesting. Meh, to each his own i guess

Yeah... The possibilities include but probably aren't limited to:
Bad cable
microphonic tube
too much gain
bad ground
microphonic pickup
broken solder joint in guitar.
