Okay so I'm looking at this amp right here http://dallas.craigslist.org/msg/315980911.html what are your thoughts on this amp? Does anyone else know about the change of the name from GC to VC for SS/tube? As for the sound, how does this compare to an actual AC30, I've read around here and on other sites that it's a bit quieter, not quite Vox but very good in its own respect. Also, what do these usually go for used (for those of you who may even have this amp). Any other thoughts are more than welcome.
