SICK metal amp!!!
The SLO 30 with a boost out front is anything but loose/flubby. IMHO it's killer for thrashy stuff but with a thicker grinding tone. With gain set at 1-2 on the lead ch and a boost, it's thrash heaven. Tight, somewhat dry, and grinding midrange. Or take the gain up to 3-4 and it's significantly saturated/compressed but with PLENTY of clarity...no mush whatsoever. Key to these amps is the presence. I run it at 10 or 11, otherwise it's a bit dark. At that level with treble & midrange to taste, it's the perfect brightness with tons of articulation.
I had seven amps here a few months back, and the SLO30 and a Wizard are all that remain. It's just a flat out killer amp. I had it listed several times but yanked it after plugging back in, and that was next to a Wizard KT150. Not on the same level, but worthy of sharing the same space in it's own right.
I may list the SLO30 again, but that's only because I recently got hit with a huge bill for some home repairs.
