With pumpkin spice in the chill of the fall air and winter approaching, you need a tone that's warm and inviting. The Cardigan is our platform for compact tube preamps, sized like our other pedals. It runs on a center-negative tip 9–12V power supply (minimum 400mA), with an internal DC-to-DC converter generating 100V for the audio circuit, delivering rich, high-quality tone that will keep you warm all winter. Perfect for adding compression and warmth to solid state amps, used as an amp-sim for ampless rigs, or stacking with other effects. Bring your favorite preamp tube to your pedalboard without compromise.
