I am not sure if this is common, But i know it isn't Serious.

Almost ALL of the patch jack inputs in the front of the guitar feel Loose/takes quite a lot of moving the patch cord to get sound, also my hi gain input is VERY crackly when i run the Overdrive Channel.

It is a used Amp that i recently purchased second-hand, the date of manufacturing is waay back in '05-06ish.

I'm not sure of how to fix this problem myself, as i have yet to try and fix it due to the worry of electrocuting myself/ruining the amp, but i really don't wanna pay $100 just to have some mook at my local guitar shop fix it in 10 minutes.

Advice/youtube video links appreciated. thanks

sounds like the input jacks themselves need to be tightend down and you may also have some cold (bad) solder joints where the wires connect to the jack.


if you are careful you won't electrocute yourself if you want to take a stab at some of this yourself. otherwise, you need to take it to a tech of find a electrical savvy friend.


what I would do is post in the Only Valveking Thread.

You have to move the jack around to get it to sound proper? Crackling when you are doing this? If so 311 was correct with the input jack/s as the culprit.

They'll be PCB mounted jacks. You gotta be especially careful tightening them up because you don't want it tugging on the board. You really need to get in the back so you can hold them as you do it. If the connections to the board are faulty it will mean removing the whole board. This is why we all hate PCB mounted jacks and pots.
You'll want to clean the jacks too but no point until you've tightened them up.

didn't know they were PCB mounted

makes sense I guess

shit i owned one and never noticed

don't keep jiggling if that is the case


unplug it, take the tubes out, unhook the reverb (red and white wires), unhook the speakers, unscrew the 4 main screws and slide the chassis out. don't touch anything on the inside outside of the jack. The green PCB and the jack won't hurt you.

seriously, read through the first few posts of the VK thread and post in there. take pics when you have the chassis out.

if it still crackles after this exercise then you may have a bad preamp tube. get some contact cleaner and spray all the tube pins with it before putting the tubes back in
