From an Online Blog:
This amp is absolutely fantastic, it really is something special.

The build quality is top notch, very high quality parts and it shows. Nothing loose, no sharp edges or uneven parts or tolex and this is a 2015.

Every dial is smooth and responsive, just the right amount of feel when turning them, not loose or too tight, just perfect. All of the EQ knobs have a wide sweep and change their individual frequencies substantially and the Bottom knob on the back can add a ton of low end but not muddy up the tone.

There is a tiny bit of transformer hum when it's on but there is no other noise and the hum is very minimal. With the gain and volume up high I don't get any noise from my speakers other than slight hiss from the volume and gain, and this is at very high volume. There are no other noises being generated. I read a review that said there were "radio noises" coming from the speakers when using a lot of gain and volume, maybe that dude had something else going on but this amp performs exactly like you would expect.

Chanel 2, hot input, 80s mode, B2 switch, EQ to taste with the gain at about 1:00 and it is a flat out screamer of an amp. Perfect 80s gain, tight and harmonic. No boost needed and nothing coloring the sound, just pure rich goodness with every riff.

The 70s mode can be just as gain heavy as 80s mode but with much less compression and much more open and raw. The amp does so well on it's own without a boost it's just plain out sick. The B2 switch adds so much to the gain stage but doesn't overdo it. It's like turning the gain all the way up but nice and smooth and with the flip of a switch it's all there.

These amps are so under the radar it's crazy. Maybe it's because of the switching names (80s, 70s, B1, B2, etc.) or the Input names (Hot and Plexi) but I can pull so much out of this thing and I've only played around on 80s and 70s modes and in the Hot input, so much more left to discover.

I also think that not being able to switch between the inputs may put some people off but I'm not gigging this and just playing in the studio I dial in my sound and let it rip and brother does it rip!

Just a high quality, beautiful hand wired, screaming beast of an amp from an artistic mastermind amp builder. Loving it.
