Take your music to new lows with the BT13 Bass Xtender! A not so secret weapon of elite bass players since 1982, the Xtender allows you to instantly drop the tuning of your low string and then back again with the flip of a lever. The BT13 is a direct replacement for the stock tuner featured on modern MusicMan® basses.
- Drop a Major 2nd (E-D) and if your strings have standard thickness cores, you can go as low as a 4th (E-B)
- DoubleStop feature gives you a tuning position between the high and low for a total of three tunings on one string
- Uses a modern MusicMan® tuning machine for perfect fit and to maintain the stock look of your instrument
- Mounting hardware included
