The Positive Grid BT4 Bluetooth MIDI pedalboard gives you wireless control of your software-based guitar effects and synthesizer presets. The BT Editor app lets you customize this rugged controller with your own presets for any music app that supports CoreMIDI.

It has four footswitches for controlling effect on/off, preset change, bank change, loop on/off and more and you can control your effect parameters by hooking up an optional footswitch thanks to the customizable nature of the BT4. While it's ideal for guitarists, the BT4 is equally at home switching keyboard presets or even navigating digital scores.

Like all Positive Grid stompboxes, BT4 is made with high-quality audio components and rugged metal construction.
