Hey guys

I have an Ibanez Jem that I run through a boss Ds-1 noise suppressor into an MXR distortion pedal (cranked), this in turn leads to my amp which is set on OD2 with treb,bass and gain at 3 (not oclock) and pres and mid at 4.

Here's the problem:
The amp is constantly hissing, making a kind of static/ white noise. This increases when I turn the gain up.

Any advice?

EDIT: Amp is a Marshall AVT275

I always thought that DS-1's were crappy noise suprresors...

ISP decimator?

Does it do it without any effects in the line? If it does, there's gotta be something wrong inside the amp. How long have you had it? Have you tried replacing the tubes?

I'd suspect a noisy tube. Those tubes can get pretty noisy, especially in high gain amps. Swap a few around (keeping track of the one you suspect) and see if the hiss changes.

Oh, my friend is having the same problem--he has that noise suppresor and it's really doing nothing for his hissing.


Try re-arranging everything.

Whoooops.

I think he might have been talking about the NS-2.

1. buy monster cables, these are better insulated and should give less noise.
2. ISP decimator could further reduce noise
3. Change your preamp tubes around or replace them alltogether.
4. move your amp away from other electronical equipment to reduce interferance
5. clean the pots and input jack
6. stand further away from your amp, and face in different directions to see if it helps

these are all possible solutions, I suggest you try them. If all else fails, get a technician to check your amp and perhaps try different pedals

Sorry, meant NS-2

One of my cables is a monster.

How much does a decimator cost?
