Features TRUE BYPASS/BUFFER/BUFFER MONITOR modes

On the FLOW TUNE, you can switch between TB(True bypass), BF(BUFFER), and BFM(BUFFER MONITOR), according to your tastes and environment.

Why is BUFFER Mode Important?

The FLOW TUNE not only features a true bypass for outputting the sound exactly as it was inputted, but now includes built-in BUFFER/BUFFER MONITOR modes.

Most electric guitars use passive pickups with a high impedance output. When using a cable, there is a perceivable loss of tone, usually high frequencies, after about 6 m (around 18 feet) and this problem gets worse the longer your cable. A buffer boosts the signal over long cables to avoid loss of tone, keeping it clean and clear – even when your pedal is off.

The BUFFER enhances the sound quality in bypass mode, so that you can still maintain superior audio quality even when using a long cable to connect to the tuner, or when inserting the tuner into a complex effects board. And with the BUFFER MONITOR mode, you can even monitor all the notes you play in real time.

Fits Any Board

Compact size and steady weight, easy to fit the pedalboard with Velcro. Additionally, the specially-designed footswitch offers comfortable pressing feedback.
