Frequently Asked Questions

The MKII has more headroom, preventing it from getting muddy at higher gain settings, and the click-free footswitch is a welcome upgrade for live performance.
While it excels in heavier genres, the mix control allows for blending with a clean signal, making it adaptable, though it’s not a primary clean boost pedal.
A high-quality, regulated 9V DC power supply with a 2.1mm center-negative barrel connector is essential to avoid noise or instability.
