The Tone City Mandragora is an overdrive pedal inspired by a very popular 4-knob boutique overdrive pedal from the USA, named after a city in Michigan. The Mandragora is perfect for everything from blues to classic rock. It's very responsive, and reacts well to the playing dynamics and style. The Pre control adds sweet harmonic richness. The Mandragora has controls for pre, volume, tone, gain, and a true bypass footswitch.
