Has anyone tried one of these for low volume gigs ? I've had a Yorkville 60 watt amp w/10 inch speaker as my small room/back-up amp for many years. It's starting to rattle & may be on it's last legs. The GK 110/112 sure look like a good replacement, probably much better. A direct comparison between the Yorkville & GK would be great, but any thoughts about either of these two GKs would be welcome. The Yorkville is simply a very portable little workhorse. Thanks
