1st impressions:
I had this in line with my BB+ so I could to do some comparisons. For reference, this BB+ has 2 boosts- the red yields tight low end response and is more aggressive, the blue is a bit fatter and yields a more natural tone, retaining more low end. I usually hang on Red for most stuff, I like Blue for some leads
First I set it up the Maxon with the tube off and slight drive, as I normally would to juice a hi gain head. First thing I noticed is that I need to crank that volume all the way up and it still is a bit less than the red at 1oclock. No matter, it sounds great. But I think I prefer BB+ Red, not sure if it is because I am so used to it. It seems more hi fi, but maybe because it is brighter? I tweak to the Maxon tone knob presents lots of usable tones. i can actually envision playing this tone knob in extreme positions and enjoy it. Tone up and gets close to Red Tone; down and it gets warmer, but not muddy.
If this was it, I may return it due to redundency, and i like the BB+ better. But back the amp off a bit into a lower gain setting (which is still quite hi), and dial in the tube and it gets some really cool saturated sustain. Very inspirational for leads. I actually liek it most when I stack it after the BB+ Red, then lots of Maxon tube into the DMoll channel 2 gain around 11oclock. very cool. So cool it's a keeper, the 'feel' is wonderful....more to follow
