Featuring a nuanced attack control developed from years of feedback, a builtin effects loop with pre/post gain and a near-indestructible 14 Ga. steel chassis, the Amptweaker Tight Drive is the final answer in the quest for a versatile overdrive. Based on hundreds of feedbacks from Amptweaker customers based on what they want in a pedal, this little tank's unique attack control takes the sound from chunky blues riff to full-on metal buzzsaw with the roll of a knob. Perfect for classic rock, stoner rock, and psychedelia.
