Hello

Thanks for your reply Enzo. It's not a "complaint". As you can hear on the linked recording the noise makes the amp unusable. I'm trying to repair it. It IS the amp. I've tried it in different places before posting.

The controls do affect the noise as you can hear on the linked recording. Gain, Volume, Bass, Middle, and Treble, and each position of the amp simulation knob. This happens on BOTH channels with the FX return knob down to zero.

SO, my guess is the noise is produced somewhere else than the FX circuit OR if it is produced by the effect circuit it reaches elsewhere somehow.

You may be right and maybe it's digital hash but, just out of curiosity, COULD it be a PSU noise? I'm not sure but I think this amp works with a bipolar PSU and I'm not very acquainted with these. Could it be a source of noise if some component is dead?

Anyway I'll check the DSP card as you suggest
Also, I can't find a damn schem of this amp. Any one?
Cheers

Hi phatt

With all due respect my guitar is not the problem. The noise comes from the amp. I'm not very acquainted with SS amps and can't locate the source of the problem.

Any ideas please?

Hi gbono

Thanks for your reply. The noise change is partially due to the guitar itself (single coils) when its moved around and partially by the amp preset selector. The noise itself seems constant to me. What changes is the EQ depending on what amp model DSP preset is selected.

I have this Fender FM212 DSP that I haven't used for a long while. I switched it on yesterday and it makes a weird noise that I have linked here:

Any ideas? Of course it's an SS amp.
Thanks for the help

Sorry, if I may sound silly, but I can't find the protel website. I'm trying to get hold of Autotrack. Any links please?
Thanks in advance
