I did a major technical modification of this student model Yamaha GA-10 amplifier and the improvement in sound quality, tone, and loudness is huge. It now cranks out 105 decibels of tone. A complete preamp, cabinet and speaker replacement. Playing a 2013 Gibson Les Paul Tribute model guitar with no pedal or effects just guitar into amp. Recorded on the Yamaha AW-1600. Enjoy!
