Guitar Tuner Guide All you need to know about guitar tuners!

The Peterson VS-R StroboRack is a professional rack-mount tuner featuring Peterson’s legendary "Virtual Strobe" tuning technology. With 1/10-cent accuracy it is up to 30 times better than the accuracy of regular needle/LED tuners. The StroboRack is the most accurate rack tuner on the market today!

Virtual Strobe Accuracy
The advantage of Virtual Strobe Technology is that no in tune/out of tune decision is ever made electronically-a process inherently subject to inaccuracy. Instead, your eye interprets the motion of the strobe display pattern as an indication of tuning error relative to the target pitch. This strobe method provides the high level of resolution, with unprecedented accuracy in tuning. It also enables the utilization of the subtleties of altered temperaments and Sweeteners™ - these are included as presets in Peterson Strobe tuners. It is this precision that also allows user-programmed tunings with up to 1/10th cent resolution settings to be achieved.

Peterson Sweetened Tuning Library
The StroboRack’s tuning library contains 34 tempered and exclusive Peterson Sweetened™ tunings, including:
GTR & BAS presets
Presets for:
acoustic guitar
DADGAD
12-string guitar
baritone guitar
E9th, C6th & Universal steel guitar
Dobro and resonator guitar
Electric violin
...as well as tuning and intonation offsets for Buzz Feiten Tuning System equipped guitars.
User-defined presets also allow the user to tie an instrument's Sweetener to a drop/capo setting in order to create a uniquely-named preset for instant recall from the front panel.

Build
The StroboRack’s enclosure is a uniquely cast piece that makes the chassis incredibly strong and impervious to the rigors of the road. All jack sockets are by Neutrik, guaranteeing optimal connection quality and long-lasting durability. The StroboRack supports use of a rear-mounted detachable BNC rack light for patching in gear under low-light conditions. Remote mute control is available with standard third-party pedals. (BNC rack light and mute pedal not included.)

Display
Even in the darkest of situations, the large, easy-to-see display allows hassle-free tuning from far away.The display's contrast is optimized for tuning in very bright environments as well, for stage or outdoor use. Easily replace the backlit StroboRack logo on the display by programming your band name, your hit song name, or anything you want your audience to read when you aren't in tuning mode.

SR-EX Pro Expander
The optional StroboRack expansion module allows users to add balanced, stereo and mono input/output jacks to an existing StroboRack, enabling use with stereo, hybrid and balanced instrument signals. An on-board, independent active DI, and footswitch-selectable channel outputs and presets make the StroboRack the logical choice for professional live & studio use.
