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?

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
