Product Description

Product Description

The BOSS "TU" line is synonymous with reliable, roadworthy and accurate tuning. Today, the world's most famous tuner prefix gets "clipped-on" with the debut of the TU-10. Reinventing the traditional image of clip-on tuners, the TU-10 offers a stylish design and robust body with high-performance features derived from other BOSS tuners, such as Ace-Pitch, flat tuning up to five semitones, and Stream mode. A unique feature - the "true color" LCD - provides a full, multi-color visual experience not seen before in other clip-on tuners. In addition, the reflection-display function dramatically improves visibility.

From the Manufacturer

TU-3 Chromatic Tuner Bringing the legendary stomp pedal quality and ruggedness to the tuner world.

Housed in a tank-tough BOSS stompbox body, the TU-3 features a smooth 21-segment LED meter with a High-Brightness mode that cuts through the harshest outdoor glare. Choose between Chromatic or Guitar/Bass tuning modes, and enjoy visual pinpoint tuning verification with the Accu-Pitch Sign function. • 21-segment LED meter with brightness control • High-Brightness mode enhances meter visibility outdoors • Accurate to +/- one cent • Accu-Pitch Sign function provides visual verification when tuning is complete • Chromatic and Guitar/Bass mode (tune by string number, with support for 7-string guitars and 6-string basses) • Flat tuning is supported with Guitar Flat mode, which allows for “drop” tunings up to six semitones below standard pitch • Tuner automatically mutes when the tuner is on

Choice of two display modes to let you know if your in tune!

Choice of two display modes to let you know if your in tune!
Everything I read says you have to have a tuner pedal on your board. So I picked this one based on other reviews. I'm a beginner intermediate player, but I understand the value of being in tune, and the aggravation you feel when what your playing just doesnt sound right. Just plug your guitar cord into the pedal and you can get yourself tuned up to exactly where your supposed to be within a minute or two... depending on the quality of the guitar and your string tuners.I have no compalint other than my $19.00 metronome and SPARK amp have tuner capabilities included. However not quite to the exact precision of the BOSS TU-3. This also has a bright display mode which can even be seen in daylight, and modes for step up and down tuning, as well as a stop scrolling lights which stop when your string is in tune, or a green light which lets you know when your in tune. If your serious about playing guitar, and you have the extra money to set out, don't hesitate. You won't be sorry.
