Peavey 115 max bass amp

#2
Could you be a little more precise about the problem? Are you saying that if you plug something into the aux input it will play through the speaker, but when you plug your bass into the 1/4" input the amp doesn't produce any sound? Also could when said you switched leads, did you mean you tried another cable from your bass to your amp?

Hello I have a CD player going into the aux input socket,and there is sound coming through my earphones,but nothing from my bass, just a buzzing sound,I've swapped guitar leads but nothing

First, is the voltage switch on the back set to the correct line voltage, and are you plugged into a properly grounded wall outlet via an unmodified IEC line cord? Probably not the issue, but having power setting correct and power provided properly is always a precursor for me.

Second, has the amp ever worked correctly for you, with that bass, either through the headphones or built-in 15" speaker? If yes, when and how were you connected? Is it possible you have a 1/4" speaker cable and not an instrument cable (an easy mistake if you have lots of cables)?

Hello ,yes I've just checked the switch it is set to 230,with a factory seal cover,the amp has worked well but there was a slight buzz from my lead,..the only other thing I can think of is a few weeks ago I put a slightly rusty Jack plug into the effects socket ,just to see if it would fit ..the amp was switched off

I am assuming you have checked the battery in your bass and that the output jack on the bass is okay. If you have another instrument you could try plugging that in. I'm also assuming 230 Volt power is what you have where you are located - if not, move the switch to the other position.

I would do two things at this point. First, place a known good instrument/effects cable (short as possible) with clean (not rusty!!) 1/4" jacks into the effects loop, and leave it there. Now open up the end jacks on your instrument cable and verify that there are no broken connections, better yet use cable tester or multi-meter to check for shorts/intermittent connections. Once these are verified good try the amp again.

Hi I've not checked the battery yet...the voltage where I am is 240...if I move the switch back it goes down to 115...I haven't got another effects cable ,having lost the original that came with the amp..

Since your supply power is 240, leave the switch in the the position it's in! No problem there!!!

Battery in the bass would be a first place to look before going nuts with other troubleshooting. You can also simply insert you good instrument cable in the effects loop input multiple times to sort of break loose any rust that may have become lodged in the switching parts and may be causing the problem you're having. Just plug in the good, clean cable and unplug it four or five times...you don't have to do anything violent. This will often help correct the problem if that's where it is.
