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
