MUTANT BASSDRUM
Analog Bassdrum & Distortion >> 13HP | 30mm DEEP | +55mA, -45mA
>> EURORACK FORMAT MODULE
>> ALSO AVAILABLE AS A DIY PROJECT

FEATURES Analogue bassdrum circuitry capable of vanilla TR-808 soundsBuilt in voltage controlled distortion (batteryACID distortion)Distortion accepts external inputs when not being used with kick drum (great for acid synth leads)Voltage control of distortion amountVoltage control of decay from short kicks to long "ooooooooomphs"Voltage control of pitch (approximates v/oct response, but not musically tuned)Non-invasive analogue optocouplers used for voltage control, thus, completely vintage sounds can still be had if that's what you're after!Completely redesigned, hi-fi signal chain spares no expense by replacing cheap transistor amplifiers with low noise opamp equivalentsYou can dial in super hot, modular level output levels (up to 20Vp-p!)
