The Tim Pierce Signature OD / Boost was designed to emulate one of Tim's favorite amps, the Naylor SD60. This is a very smooth, warm, punchy drive made to really shine with singing leads. The Power Amp section is fat and loud with nothing but punch, designed to emulate the sound of a full blown tube power amp using 5881's. Both sides can be used separately or cascaded together, giving you a distinct 2 in 1 pedal. True Bypass. Power: 9 V Negative tip not included, 9 V battery. Dimensions: 13,9 x 8,2 x 8,2 cm. Weight: 0,81 kg.
