Ratings and Reviews for  GSS Twin Sumo stereo bass & guitar power amp

This amp is wonderful. Able to power my stereo 2x12 with ease. Very clear and transparent. The size of the unit is perfect and can fit into my rack with ease. A very slick look and very simple which I love. Currently getting a video together for the people at GSS so that more people can see how great this product is. Stoked to be a user of GSS products!

It's a fantastic amplifier, heavy enough to be reassuring without being cumbersome, really quiet in use, even when turned up loud. It's great having the flexibility to run it either as a stereo amp, or a single channel amp and not have to worry about needing a load connected to the other output. The sound is really clean, very full, especially with a valve preamp in front of it, but unlike some power amps I've tried, it doesn't seem to be lacking in the mids. Overall it's excellent.
