JFET Mini Booster


When you want a clean booster that adds amp-like chime to anything placed after it, there’s only one semiconductor you need to reach for—the JFET. Thankfully for you, we’ve taken the architecture of our JFET preamp we use on many pedals and placed it into this, the JFET Mini Booster.

If you’re already in love with the sound of your amp—or you want to be—the JFET Mini Booster is just what the doctor ordered. It contains a rich, high-end sparkle that’s as dynamic as the day is long.

The circuit structure is designed such that minor changes in surrounding gear make for big tonal changes. You can try running the JFET Mini Booster in any position that needs a bit of a tonal lift to great results.
