As someone who has owned a number of valve amps, this amp amazing, the cleans are as clear and warm as a fender twin and the od2 channel has as much growl as any marshall head I've used.
For anyone who uses a loop but hates how changing from clean to overdrive distorts everything recorded, that doesn't happen with this, whatever channel you record in, the overdubs stay the same even as you change from clean to overdrive and continue to record.
The included foot switch works as a channel switcher as well as the control for the loop function.
The effects are what's to be expected, reverb, delay and modulation, and three variations of each.
The isf dial is really as good as it claims ( which I was skeptical about at first) but it really does get that classic rock sound right up to the modern full bottoam end metal sound.
All that and it's quite small and very light!
5 stars all round.
