I've been using one of these for about 18 months, I did have fault problems to start with, Marshall sent me a new one, but since then it's been fine, I use it with a 1 x 15 extention cab, (not a Marshall) which gives it a lot more bottom end grunt, and I think I must be in a minority of one cause I use the modern channel but I do use a zoom 506II to add a touch of distortion, really happy with it, get the sound I want with loads of head room
