I received my BluGuitar Amp1 a couple of days ago. And I have looked forward to it. The youtube clips where very convinsing, and the JTM45 sounded amazing.
I have plugged it in on a cabinet with V30 speaker, as adviced by Thomas. But the sounds where not my thing. The clean-, vintage- and classic channel had to much high frequencies. I compared it mostly with a fender supersonic 60, which is a very treble amp. The high frequencies hurt to my ears. Funny is that lowering the mids had most effect on this, more than lowering the treble. I also attached it to the speaker of a combo to be sure it was not the cabinet. Same sound.
The sound of the vintage channel gets much better when you open the gain. It rolls off lots of spiky highs.
But I like my amps for much headroom, very clean. And my drives are from pedals. The headroom of the clean and vintage channels is not enough, it compresses the OD's, I loose to much of the dynamics that I have with a 50+ tube amp.
The concept is great, I was loving the idea to have such a small top, combined with a nanocab, for gigging, jam sessions etc.
But, as I prefer a good sound over light travelling, I will send it back.
Btw. I did not really like the small knobs on the side, difficult to set them. On the other hand, the idea is that this is a one time setup, and you leave it there. But when you are searching for a good sound for initial setup it is not that handy.
