GuitarPCB released the Sonic Tonic v2 in February 2023, a revised version of its circuit board based on the BBE Sonic Maximizer¹.

The maker says the circuit "restores clarity, definition, and dynamic range to your music" and "works by correcting phase relationships, restoring harmonic content, and increasing perceived loudness"¹. Those are the maker's claims for the design.

The board measures 2.10" x 1.53" and carries two potentiometers, marked HIGH B50k and LOW B50k, along with a TL072 (IC1) and a TL074 (IC2)¹. The parts list specifies a 1N5817 diode at D1, and D2 is a status LED that the maker says can be either a bi-color common anode or a standard on/off type¹. The document also includes a wiring diagram and a drill template¹.

The v2 changes are listed by the maker as:

The listed changes are an added (D1) 1N5817 circuit protection diode, on-board potentiometers and a better cosmetic layout¹. No price or availability date is given in the document¹.
