Visit many good tones, but live in the versatile ambience of the Spurgeon Reverb V2. The Spurgeon Reverb V2 covers all sorts for ground – from classic spring to washy plate and hall tones – with the flick of a switch. Along with the traditional Mix, Tone, and Decay controls, the Spurgeon V2 features a Regen knob, which feeds the higher frequencies back into the circuit for subtle modulation to enormous oscillation.
