Erica Synths DIY Bassline is a fully analogue synth voice module for ultimate acid basslines. It features highly stable AS3340-based VCO with three wave-forms, a filter inspired by Erica Synths Acidbox and a unique feature - transistor based suboscillator.
Accent provides more expression to the bassline by adding volume and slightly opening the VCF.
  • Full analogue circuit
  • Great 1V/oct tracking
  • Simultaneous Triangle, Square and Master outputs
  • Accent
  • Transistor-based suboscillator
  • VCF and VCA decay envelopes 
  • External VCO FM and VCF cutoff CV inputs

 This is a comparably complex DIY project for experienced builders. We do not recommend this for beginners and ones without proper soldering and testing equipment.
