Amp Doctor! Please advice.

Hi,

I just bought a Roland JC120 last week. Its very loud! Have good shimmering cleans, as u would a JC, & respose well with pedals.

There r some problems, though.
- the vibrato & chorus doesn't work. i think it needs an IC replacement.
- there is a 'thud' sound, whenever U switch it on.
- there r still audible sound, from your guitar, even when the vol knob is turned to '0'.
- it eats the internal 3.15A fuses like peanuts.

Anybody out there who could diagnose this?
