*หมด*BOSS TM-7 Guitar Monitor (MADE IN JAPAN)

The TM-7 also has a "center canceler", which effectively removes or erases the audio signals which originate from the center of the sound field. Most commonly these centrally-located signals are the guitar solos and the vocals. Using this feature you can rehearse your solos without any obstruction from the existing solo or vocals. The TM-7 allows you to mix in your choice of external effects using the built-in effects loop (with a stereo return). You can also use the stereo mini headphone jack to practice without distrubing others.
