The classic tone of the ’70s, the low pass ladder filter defined “the synthesizer sound”. The MOTM-490 captures all of the subtle characteristics of the original; growling bass, searing leads and overdrive. Can be used as a VCO above A440. Filters any external audio signal.

• Classic 24dB/Oct LPF Ladder Filter
• Based on the Moog 904A modular sound
• Three Audio Inputs
• Distinctive Overdrive Sound
