The Yamaha THR10 Modeling Combo Amp is an off-stage amp. It pretty much boasts real tube amp tone and dynamics, great sound at low volume, genuine hi-fi quality stereo playback and full recording capabilities. The THR10 was developed with Yamaha’s award-winning AV division to offer true hi-fi stereo sound and a new experience in guitar amplifiers. All in all it looks like a pretty awesome beast. And most of the rating on the website seems positive so I guess it’s a worthy investment.
