All Tube Amp Head for Electric Guitar

Latest User Reviews
Best all valve head in it's class.
Sounds mega and don't let that 15w output let you think for a moment that it won't be loud enough for you. This thing roars plenty loud and I even have it going through an attenuator to keep the neighbours happy.
Quite happy with this. This amp has a great clean channel and a lot of versatility with it's "Boost" and "Push" options, making it a great pedal platform. The Distortion channel is also decent, although it can be quite fizzy (especially with lots of gain) and it comes out quite bass heavy on the harley benton 2x12 with v30's I'm running it through. I find it really needs a tube screamer style pedal to get the mids and highs to cut through well (I am using a power soak which may be increasing that, and apparently you can put a patch lead in the FX loop and use the send level knob to reduce volume). Build quality feels solid too.
I may change the tubes at some stage to see if that cleans up the fizz but with more mild gain settings it still has pretty thick distortion and most of the fizz cleans up. Overall a great amp for the money (considering I paid 1/2 what a second hand Mesa Mini Rectifier costs here, and I'm pretty sure this is a clone of that) and potentially really great with a tube change.
