I haven't played either amp. I did play with a guy who used the DG-80 and it sounded good, but was pretty susceptible to outside noise (stage, lights, etc.) I have always had great luck with Yamaha quality. I have an old 1975 FG150 Accoustic, a 1995(?) LD-10E Acoustic/Electric and an SY-22 Keyboard. The guitars play great and stay in tune. I have had no problems with any of their gear. I haven't used their electric guitars or amplifiers, so I don't have any info there.
