"Besides doing beautiful work on my bass, I have sent countless students to Mark to buy their first basses. Mark orders the basses but then does his magic set up job....making the basses play evenly and with a beautiful action....perfect for young students, first time upright players, or any one for that matter. His 'tune-ups" and repair work are reasonable and he stands behind every bass he sells. I'm glad he is around."
