The new VersaTune ($199 Street) is a rackmount design that, with it's easy-to-read LED display accompanied by a large note readout, offers excellent visibility under any lighting condition. The VersaTune features such amenities as dual inputs and outputs (with both on the rear panel as well), and the ability to switch between inputs via front panel switch.
The VersaTune's LED readout is very stable, which makes tuning a breeze, and unit includes a library of 100 different tunings, which you select with the up/down keys on the front panel. Tunings are displayed in the backlit display on the right, along with indications for how to tune each string to achieve that particular tuning - be it dropped, open, or any of the tunings available for dobro, banjo, dulcimer, mandolin, 7-string guitar, 6-string bass, and myriad others, including ethnic instruments.
The VersaTune features a tough metal housing and an internal power supply, so you can connect it directly to a wall socket without the need for an adapter. All in all, an excellent tuner for rack gear aficionados. - Art Thompson
