Independent shopping perspective

Gain and Master Volume work with a four-band EQ, while the Scooped and Boost switches add further tonal changes. Connect an external audio player through AUX for play-along sessions, or use headphones for private practice. Its unbalanced preamp output can also send the preamp signal to a PA system or mixer for rehearsal or performance.
