The Amptweaker TightBoost is a versatile boost pedal designed to drive your amp harder with a clean boost. It features a Tight control for adjusting the amp's attack from smooth to aggressive, and a Mid boost control to add a 'Parked Wah' tone. The TightBoost uses the same distortion methods as the TightDrive overdrive, offering a warm, tube-like breakup when driven hard. It's ideal for a solo boost or overdriving other effects.
