The Hotone Soul Press II is a 4-in-1 effects pedal, offering versatile functionality as a volume, expression, wah, and volume/wah pedal. This updated version features real-time tread-plate position indication, and 'Tone' and 'Q' controls, allowing players to shape their wah tone. True bypass ensures a pure signal, and the pedal can be powered by 9V DC or battery. The Soul Press II builds on the success of the original Soul Press, offering a more ergonomic design, with multiple input/output options.
