I've had the Blue Rock for many practices and several gigs now, so thought I'd give some more feedback.
I have a standard setting now to get the deep reggae tone, all 12 o'clock apart from bass, which is 3 o'clock this gives me a very similar tone to the almighty previous benchmark Avalon U5 into Crest CA9. The Crest had HUGE bottom end, and the Rock needs that bit of boost to equal that - possibly the difference between enormous transformers and class D?
I'm very pleased to conclude that the Blue Rock has clarity, definition and bollocks at band volumes. No sign of falling out of love with it - if anything I love it more the more I play it.
To be fair, most if not all of my gigs go through the PA, so my band volume amp-only experience comes from practices.
I've had several compliments from soundguys though.
No real test of the drive section as it's not relevant for my band (any distortion I use is synth-flavoured from pedals) but nice to know I have it anyway.
My master sits on 12 o'clock and that is very loud indeed.
I have a slight irrational dislike that I have to tweak the bass control to achieve my ideal tone (ie it's not baked in flat) but I suppose it's like a car's default seat position - you set it how you want it then leave it.
Overall, I'm bloody loving it.
