Peavey 6505 prone to feedback?

[Rumble]

I've got a stock 6506 head and cab. I can't seem to get any volume without massive amounts of feedback. Is this normal for this amp? My pre-gain is usually around half and presence and resonance are close to full on. As soon as my post-gain gets up to about 2, the nightmare begins. This is regardless of guitar and normal/high gain input.

My friends' Marshall valvestate didn't have any problems in the same, smallish room.

Any thoughts?

Welcome to the world of high gain tube amps.

become a master of guitar muting or get some noise gate device i spose

ISP Decimator

Problem solved.

 

[hogan666]

got the same problem.
Hate it, but good to know I'm not alone

Cheers

Heard a lot about ISP, but it isn't available in Germany.

If you can't get a hold of an ISP Decimator, go for the Boss NS-2. It's also cheaper.

first off i'd say turn your pre-gain down to about 3.5-4 (honestly that's all you should need with the 5150) you may have to bring up the volume a bit, to compensate for less gain

also try bringing the resonance down to around 5 and the presence around 7

that's about where i keep mine set, and i have no problem taming the feedback

I guess 'need' is all relative but this 3.5-4 seems pretty low to me. I concur w/ the gate suggestions and would add the obvious 'move away from the amp.'

3.5 - 4 is low on the Rhythm Channel, but it's more than enough on the Lead Channel.

 

[Genius Gone Insane]

Just to make sure, what kind of pickups are you using? Shitty pickups can do that...

+1

on the rhtyhm channel i usually have it around 5-6 with a boost

on the lead channel having it above 4 is A LOT of gain tho (don't let the low number fool you) i understand some people may like it that way, in which case a noise gate probably will be your best solution

I run my pre gain on the lead channel at around 6.5 on my 6505+. Sure, I could run it lower, but I just don't like the thinner tone. The tone seems thicker and more robust with the added gain. If I could achieve the thickness at a lower gain setting I would, but I just don't think the amp sounds as good with the pre gain that low.

On the other hand, running the pre gain around 6-7 on the rhythm channel sounds as thick as the lead at the same setting, only less gain. I don't get it. I need to get a boost for the rhythm channel, as I really think I'd like that channel more.

just keep the fucking gain down, dammit. gain whores.....

i rarely use the lead channel for rhythm work, i just happen to prefer the boosted crunch channel. however, if i do so, i NEVER turn the gain past 10:00. i run it at 10:00 using a slight boost for LEADS, so go figure....

and btw, did i mention that i get ZERO feedback problems?!

Haha, I run the gain on my amp all the way up, and don't get any feedback issues - ah the wonders of crappy hybrid amps...

the 6505+ has less gain than original 6505 (or their 5150 counterparts, if you wanna be technical) that's about equivalent to having the gain around 4-4.5 if it were the shared eq version

 

[sorceron]

yea the ns-2 is a good investment for sure with this amp. i get less feedback using 81's though

 

[Death Is Certain]

With the pre gain at about noon I don't get any bad feedback, what pickups are you using? Get quick with your volume knob or get quick with switching back and forth between channels. Unless you're facing your amp and you have really hot passive pickups, then I don't see how this could be happening.

 

[Rumble]

I use a Les Paul, but it happens with any guitar you plug in. It doesn't just sneak up either, it tries to feedback before after and between every note.
I tried lowering the gain but I still have problems.

You may have a microphonic preamp tube. Try switching the 12AX7s around (especially in V1) and see if it goes away, for a short term fix. If it does, you may want to replace your preamp tubes...
