Mine was an impulse buy on Ebay- for £99.00 and was a month old -I have the box & tags that came with it. Mine now has a couple of GE vs in it which reduced the volume slightly but I swear sweetened the tone.This came about because I'd taken the amp to my amp tech guy who has become a friend and I was merely showing it to him and he said something like" I wonder what it'll be like with these in it...." and so we tried and we both noticed the difference. The amp was already great sounding but was even better after. I thoroughly recommend these amps- plenty loud enough for rehearsals- very portable and as I said earlier, I have even been able to use them for small gigs. In fact I am tempted to try sticking a mic in front one of these days.
As sgmypod says, they take pedals extremely well. With my Trex Tremster ( another Ebay bargain) you get a lovely buttery warm tone. I stuck my spare Jekyll & hyde in front of it too and was very happy with the tone. I will be using it to record with soon I hope.
