So I now have one of these little things.
Firstly, it is very pretty, like a tiny Marshall Bluesbreaker. Its very simple, single channel, volume, treble, middle and bass. The 10" Celestion in it suprises you, a lot of noise comes out of this thing including a lot of bass! Under 4 its the usual valve clean, over that it gets crunch, way over that it gets dirty. This thing is suprisingly loud too, think it may even be giggable..
Downsides so far, tube rattle. Has 2 12ax7s and a single EL84, and I think the cheap chinese EL84 is rattling like a cheap watch. Will contact Mr Valve tomorrow and see if he has a NOS Mullard, if not just a replacement Sovtek and see if that resolves the issue.
