The TONE-BURST™ Boost/Overdrive offers a virtually transparent gain range usually associated with “clean” boost pedals. However, the TONE-BURST has enough gain to boost your guitar to the threshold of clip and slightly beyond, making it far more useful for a variety of applications. It’s incredibly powerful for adding boost, drive and/or EQ to any guitar and amp combination. Whether using it as a utility to boost the output of single coils to match a humbucker or as a subtle overdrive when a standard overdrive may be too much, the TONE-BURST is an incredibly useful and expressive pedal that makes the best things sound even better!
