bass amp trouble

[zeglover]

started to play my bass guitar again after a long while of not playing it. i get a horrible hissing sound coming from my amp, i am pritty sure that it is the amp as i have 2 basses and i get it with both. i is more noticeable my active bass.

the level of hissing changes with the amount of treble i use ether on the guitar and on the amp.

but i can nearly cut out the hissing by tutching the lead that connects guitar and amp.

never used to do this.

any ideas

stu

ps the amp has been stored in my room so it hasn't been stored in a damp garage or shed

Sounds like you have a faulty lead. Do you have a spare to try?

First of all, ignore the amount of treble.

When you switch on your amp, and BEFORE, you plug either guitar in, is it hissing?

If the answer is no, then it probably isn't the amp.

If you then plug in either of your two guitars and then thats when the hissing starts, it suggests that your lead may be faulty. Especially as you say it stops if you touch the lead. Try a new lead - and try with both guitars.

but If its hissing before you plug your guitars in, it could be the amp that's faulty.
