Hi DrGonz78

Amp made/assembled July '95.

No; neither tech even mentioned filter caps. As said before by Roly and Enzo, they advised checking for solder cracks. In reading other info here and elsewhere...it is likely, after 17yrs, they're a done thing. However, I will check with meter (after discharging).

Do you think that the filter caps are now looking like the culprit/s?
Most advice out there is just to replace ones that are this old anyway.

And one more thing to add;

When strumming, and the signal distorts (when expecting 'clean') and drops, there is a buzz, particularly when strumming hard on the lower (bass) strings.

Cheers. 8|

Thanks Roly and Enzo  :dbtu: for your suggestions - really appreciate your help so far.
What I have tested to date;

• Input  -wiggled cable jack in input. No difference.(No loose solder points/contact points?)
• 'Whack it' test - vol up with no reverb, No audible noise but the smack of me fist! (SO, possibly no loose connections?)
• Guitar direct in Efx Return - No difference. (points to power amp section?)
• Cable connecting/between Efx send and return - No difference.

So, by the above, it seems like the power amp section - what do you think?

Do you masters :tu: have any suggestions how I should proceed from here?
Any thoughts greatly appreciated!

AND...Merry Christmas! :cheesy:

Thanks everyone for your suggestions...I will try them in a couple of days and post result. Cheers  :dbtu:

Hi All - I have a Fender Performer 650 bought used. Love the amp, LOUD, great clean and using the overdrive.

Recently, the signal drops on strumming guitar harder (or jumps in level), while also being distorted (but on the clean channel). Presently it is unusable.

Frustratingly, I have taken it to two repair outfits; one flushed out the pots, said it was repaired (NOT! - which I discovered that night at sound-check!) while the next one tinkered with it for three weeks and then in the end I got them to agree they weren't able to detect problem.

Any trouble shooting tips would be greatly appreciated as this has been going on for over five weeks - I have replaced components, mod'd pedals and guitar electronics. If this can be solved I will make a decision whether to repair myself or get someone else to do it, but with more knowledge this time.

Thanks in advance!
