So, I used the amp a few times over the past few weeks, in a rehearsal and two live situations.
The D and G strings tended to dominate - that was a deliberate choice on my part, as I wanted those notes to cut through. When the guitarist complained about the
volume, it was easy to change my technique and cut back on the treble. All in all, the smaller cab seems to give a tighter, more aggressive sound than the Ashdown cab and head that I am more used to.
I still don't know what the Aural Enchancer does - but the rest of the amp does a job, and has a small footprint.
For the £20 that you paid, you can either use it as a cheap combo amp, or convert it into a bird box big enough to frighten the neighbours ("yeah, mate, eagles used to nest in the area back in the 1850s, and the council want to reintroduce them as part of the rewilding project....")
PS the cooling fins on the back are necessary. I don't play many songs in a set, but have found that the fins get warm. If I was going to use it for a one hour set, I would perhaps put a little PC fan on a bracket to mitigate the warmth.
