Not sure what's causing a clanky noise when I crank it but since I've bought it for like stupid cheap I really don't want to brag about it. Might fix it up one day but probably will go for a new amp instead.
I've used this amp for about a year now, and it kicks out some pretty good tone considering the fact that its solid state and has a small speaker. Overdrive channel is nice, but wont get the distortion you'd hear from a nice Orange tube amp. The amp can keep up with a drummer as long as they don't slam on their drums, but with a larger band it will definetly be drowned in all the sound. A bright clean tone can be brought out of the amp with some tweaking on the EQ knobs (I have mine set with the Mids at 9 o'clock, the bass at 11 o'clock, and the treble around 1 or 2 o'clock). Driving it with a pedal, it can achieve heavier distortion and still sound good. Overall, I have really enjoyed the amp and what it offers.
