I purchased this amp from the Gear4Music B stock on eBay. Knowing it had issues with vibration noises.
After a couple of hours tracking down some of the vibration to a loose baffle board inside the cabinet. I glued it in place and reassembled the amp.
I also found the speaker grill was vibrating, it had 6 screws in it, I doubled them up to 12 screws. This stopped that all the noisy vibrations.
The sound from the amp is excellent now, it handles my Bass guitar and a microphone via mixer with ease. The voice sound is clear and the Bass is well defined and not muddy.
Also, it handles our drummers electronic kit very well too.
