The Tone City Mandragora is a low-gain to medium-gain overdrive effects pedal, inspired by a very popular 4-knob boutique overdrive pedal from the USA, named after a city in Michigan. The pedal works equally well in front of a clean or already overdriven amp and offers two individual tone controls to shape the tone of your setup. The Pre control combines gain and tone adjustments to add a sweet harmonic richness while the Tone control covers a wider frequency range to shift the overall sound of the pedal.
