Hy guys
I am facing an issue with my vocal/guitar AMP+speaker.
when i bought it a year back even on full volume its sound was natural no fuzz or distortion when guitar or vocals are done through it.......
now it fuzzes on high volume.... i use digitech processor so it changes my tone a little bit on both guitar and vocals waiting for response.......
Regards

Do you have a different speaker that you could try with it? I had an amp that started making a weird (but cool)  sub octave fuzz sound and it turned out the speaker was bad. Hope this helps.
If it sounds good, USE IT!

I pluged my studio headphone a little back in the output jack to check whether its the speaker...... headphones fuzzed too....
in the picture i uploaded it cannot be seen but there are capacitors and transistor in this amp......... how to check them?

Do you have basic knowledge of electronics? If not, it would be best to talk to a friend who knows of it and is willing to help, or take it to a trusted tech. "Fuzz" could be many things, from the power transformer to a single bad resistor. It's very rarely a "look and shoot" kind of thing (speaking as a tech who sees weird, new issues everyday).

Agree and add: you seem to be looking for "bad parts" but that is just one aspect of the problem.

If amp sounds good at low/mid levels but distorts at high level, that's normal.

If 1 year ago you could set the volume control higher without problem, it's possible (in fact I'm quite certain) that your audio processos adds some gain *and*  boosts extreme los and highs, both being a challenge for your present amp and speaker.

Both add up to push amp further into clipping you don't like.
