Gallien Krueger amp needs looking at in London. PLease Help

[Guest BassKS]

Hi Guys,

I need this one looked at if poss. I was told it needs to go to Beyer Dynamic in Brighton!!! I dont drive and its definitely not worth doing all that trip for crackly pots if someone more local is able to fix them.


Thanks

If it's just crackly pots then the chances are you can fix it yourself with a screwdriver and a can of switch cleaner a damn sight quicker and cheaper than lugging your amp around and paying someone to do it for you.

Do it yourself with a can of WD40.

yup, you guys is right. I also feel that there is a bit of a "snore" coming from the cabs, a hint that they might have blown/ripped/ and may need repairing. Im kind of thinking if its worth servicing at 100 odd quid or just buy a new one. GAS has a lot to do with it.

Well if you have a ripped cone then get some tissue paper - make a small patch to cover the tear and use Copydex to glue it down.
Build up a few layers (front and back) over the tear.

The Copydex dries like rubber and is very flexible - it soaks into the tissue paper and gives you an airtight rubber patch over and around the tear.

To test if a driver is blown, remove the front grille, lay a plate face down in the cone and gently push it down.
The cone should push down and spring back freely - if you hear or feel a 'grating' then the voice coil is probably melted.

Whatever you do, don't spray WD40 into pots to stop them crackling, always use proper electrical/switch cleaner,

Ive been having the same problems with my GK 1001RB-II. Is the solution really as easy as that?

Ive never even looked inside an amp before, but I dont know anyone close by who does amp repairs. If its something simple then im sure I could have a go myself.

Yep.
There are a few things that could cause that 'crackle' but the first thing any sensible amp tech will do is give it a blast of switch cleaner to see if that fixes the problem before moving onto deeper diagnosis.

This guy serviced my G-K 800RB a few years back. Did a good job. http://www.guitaraid.co.uk/
