Hello,
I offer for sale guitar active onboard preamp EQ-Boost (Based on VSC-3): https://analogworkshop.eu/products/eq-boost-external-potentiometers/

This is the same EQ-Boost preamplifier, which is already well known, but this time it was equipped with an output for external potentiometers. Thanks to this solution, the equalizer control can be led to the front panel of the guitar, or even use this module to build a stompbox preamplifier

  • Low noise op-amp on board,
  • Handmade, high quality, each preamp tested,
  • Power: 9V battery (the battery is not included),
  • 3EQ: 150Hz, 600Hz, 7,5kHz
  • Low current consumption
  • High input impedance,
  • Low noise,
  • Small size: 39 x 34 x 8 mm
  • Easy installation on guitar,
  • Included: manual (pdf), battery connector, 6.3mm stereo jack (socket),
