Sound: I currently use a 5 string bass with it and it has no problems with handling low notes. The EQ works brilliantly and gives you a nice variety of tonal options and turning up the presence helps you cut through the mix a little if you're practicing with a band.
Unfortunately it struggles to maintain tonal clarity if you turn the master volume anywhere near 3 quarters max, fortunately for me it manages to be loud and clear enough to be used for practice (even with the noisiest of drummers). This makes it adequate for practice, during a live scenario however the distortion from having to turn up the volume completely destroys the tone. // 6
Reliability & Durability: It seems to be solid enough, I haven't come across any problems with it in the 3 years I've used it. The sound quality hasn't diminished during this time despite being used regularly for practice, as an amp for my electric drum kit and for a few months (reluctantly) gigged with. // 10
Overall Impression: Overall it's a fair little practice amp, nothing mind-blowing but at the same time it's not crap either. It's perfect for its purpose however it's just shy of being viable to use for even the smallest of gigs. The main bonus for me is that it's easy to carry around, it's no fun lugging an 87LB amp around just for practice. // 7
