Description
J. Rockett Audio Designs built this pedal alongside session legend Tim Pierce to capture the character of his go-to amp, the Naylor SD60. The overdrive side delivers a smooth, warm grit with plenty of punch behind it — the kind of drive that lets sustained lead lines breathe and sing rather than fight for space in the mix.
The second half of the circuit is a dedicated power amp section, voiced after the fat, loud push of a tube power stage running 5881 tubes. Run it on its own as a solo boost, or cascade it into the OD side for a thicker, more amp-like push at the front of your chain. Because both sides work independently or together, this single enclosure covers two very different jobs on a pedalboard.
Controls are laid out for quick tone-shaping on either side:
- Drive — sets grit/overdrive amount on the OD side, and shapes grit when cascaded with the boost
- Level — sets OD volume alone or contributes to overall volume when cascaded
- Bass — dials in low-end fatness for the OD side or the cascaded signal
- Tone — controls brightness/presence for the OD side or the cascaded signal
- P. Amp Switch — engages the power amp section alone or cascades it with the OD
- P. Amp Knob — sets boost volume alone or contributes to cascaded output
- On/Off — engages the pedal
Even set at unity gain, the power amp section adds amp-like density to your tone, making it a handy always-on utility as well as a solo-boost tool.
Like all J. Rockett Audio Designs pedals, it runs on a standard 9V BOSS-style adapter (5.5mm x 2.1mm, center-negative) or a single 9V battery, with the battery automatically bypassed when external power is connected.
