So I bought a Peavey Combo 300 and when I tried it out I was happy with it, albeit it was quite but the guy dropped it off early hours and I didn't want to disturb the household. Just turned the pre/post gain up and it's making no change in volume... Am I missing something or do I get in touch with the guy and tell him it's poopie and I want a refund.

Peavey Combo 300 TOO QUIET?!
- Thread starter Remy Yeldrem

What else have you tried? Are you going into the low gain or high gain input? What are the rest of the knobs set at? Have you tried your bass with another known working amp to make sure it's working properly? Are you using a good signal cable (and not a speaker cable)?
Troubleshooting requires quickly making a list of what the problem ISN'T before diving into what it could be.

I've been playing the bass all week in a variety of amps, and it's sounded fine. Just plugged into my Blackstar and it's sweet. I've plugged into both low and high input and set all the knobs at a variety of settings but no joy :/
Think it could be an electrical issue?
Tone, yes! The EQ controls work perfectly, but the volume doesn't change at all.
Interesting. Have you tried both push and pull positions on the pre and post gain knobs? And do they turn like they should?
Push and pull? And they turn smoothly, doesn't feel like they're too loose or anything like that.
Both knobs on my 130 can pop in and out. For punch and bright. Hard to imagine a problem with these sturdy eighties peavey pots
Pull the knobs out. They should "click" in and out. If I recall, one is a bright switch and the other is a bass boost?
There may be some crud in the pots. Pull/push them in and out and turn them 0-10 a few times.
I bought one many years ago when my wife and I did a hotel circuit.
Liked it so much I bought her a KB300. Fast forward to club and non-
lounge venues. Not nearly enough (160w) power. Least for me.
Regardless of the EQ boosts. Gallien Krueger 400RBIII and 700RBII these days.

Try the old short instrument cable in the effects send/return (preamp out/ power amp in). Sometimes this works magic on old amps.
I have a 400RB and a 700RBii. Will keep my Peavey TNT 130 combo though. Great amp. I’m sure the 300 is more of the same
Does it work in the other direction? Can you turn it down? Looking to see if the pots work at all.
Try an experiment- put pre gain at zero and post gain all the way up. Slowly dial up pre gain and see where it maxes out.
Without hearing for ourselves or seeing exact settings in real time it's a little hard to troubleshoot but it is possible you have it maxed out. This might help determine what the problem is.
I had one. They are very loud. If yours isn't you need to have it repaired.
I had one, loved it, sold it because I went to a multi cab GK rig...its one that got away...
Ping Peavey about it...they have pretty good customer service...they may be able to help you out. Mine had a cap fail and they helped me ID which it was and what to replace it with. Solid amp...its probably something simple.

Working properly, that amp will be a danger to any children or small animals within 100 yards.
You mention another amp. Does that other have an effects loop? Try the pre out from your other into the power amp in on the Peavey; does the Peavey respond to any volume or gain knob from either amp? (since you haven't specified if the other is master vol or not) Also Try the same thing in the other direction, the pre out from the Peavey to the power section of the other.
My assumption, since the EQ works and you get some volume, it's likely something is dirty or corroded in the power section. I wouldn't first assume its a knob but it is possible. Of my 2 Combo 300's, one needs a jumper in the effects loop to hear anything at all (as opposed to your issue), so while I hope it is a simple fix I think that would not be the primary fix here. A can of deoxit never hurts with these old guys and I hope you share in my experience that it's one of the few tools actually needed with these unstoppable amps.
Good luck and do yourself a huge favour don't leave the pre or post too high, (maybe 2 or 3) in any of your testing, once you find the issue you could make yourself deaf.
