    good as expected from Marshall

  • Trevor Llewellyn


    This is a fantastic amp. Valve amps sound much better thany any other type in my opinion. This 20W Marshall is a great companion for the 40W Fender Hot Rod Deluxe IV I got from GAK which also has a superb sound. Marshall best for distortion and Fender best for clean though both are great for both.

  • Mark Willis


    Star rating of a Marshall combo depends if you like that "Marshall sound". I do and this amp does deliver it, from clean, through gritty, to over-driven screamer. Switching to 10W setting retains the sound quality and makes it usable at home without disturbing the neighbours too much. Responds well to guitar volume setting and single coil/humbucker switching. The rear aux-in is useful for jamming and practising with other music sources. Comes with foot switch for selecting clean or ultra-gain channels and FX loop on/off. It's a Marshall, it's got valves, what's not to like?
