It is the GS 112. I mentioned it as an alternative to a 15 in speaker. Alain, if you are still monitoring this thread, I have found this speaker gives me more than I got from a Bag End 115 SD. It has an attenuator, and weighs less than half than any 15 I've owned. On larger gigs I elevate it and it is pounding out funk on a large scale. It is the first speaker that has fulfilled all my requirements. Weight, tone, volume,attenuation, size,multi-jacks for input.
