GK 115, great bass amp. Fairly lightweight for the size. There is a slight hiss when you have the tweeter turned on, but from what I have read, all these amps do that and it isn't at all noticeable when you play. The only time I had the tweeter on was when I was playing to a track and had a track playing through the amp.
I believe this is 200 Watts. Great sounding amp! $150 obo.
