I posted this in another thread that I started, but here is another review after some more time with it. It was also great to sit back and listen to Poon play it. He possesses a nice touch and is also a good player.
From the other thread.
I have now played with this amp on 8 gigs in 10 days, ranging from large clubs(300-500) to dive bars. It definitely continues to deliver. Using this head with my 4ohm SA410, and 4ohm SVT810, I have some different opinions. However, once again, I am confirming that it is a good tone right out of the box. Similarly to the LMII, the amp sound changes with each different cabinet (No Brainer.) However, I found that the common characteristics are headroom and a richness in the low mids. This goes across the board whether I am using a 112 or the 810. Now with the 810, this thing is just so loud. I was really, really loud with the gain at 1:00 volume at 12:00 and master at 8:30. 9:00 began to shake the walls and drown every body out. This was with the EQ set relatively flat. In other words, this puppy has the potential to quake. Where it was missing directly compared to my DB750 were some lower harmonic overtones that the Aggie is known for, but with the 810, it wasn't by much. Cranking the gain a little more and low mids, it came pretty close to the really warmed tones of the DB750 with a little bit of drive from my Sans amp BDDI, it was 90% there towards an SVT tone. AT FOUR FRIGGIN POUNDS!!!!!
So, I reiterate that this amp is versatile, sparkly when necessary and warm when needed. Depending on my mood and speaker combination, I've found the sweet spot for me is adding a little bit of low mid, or cutting some high mids ever so slightly with the bass a little past noon, and treble right at noon. Once again, the knob design allows me to remember my settings. For example, "x" amount of clicks before or past noon.
Through the 410 rig, it definitely needs a little more ooomph and push to make it sing, but it can still get there with relative ease. I'd like to try it through other 410's.
Also, through my gigging reports, I have yet to feel this amp even break a sweat even after pushing 4ohms for 4 hours straight.
FWIW, I have intermittently used other amps, so I really do feel these are not "honeymoon" type reviews.
