The Obelisk Vintage Drive is an op-amp overdrive voiced to achieve the legendary ?brown sound? tone of the 1960s and 70s. It uses a 4-position rotary control for three different parameters: tone control frequency, tonestack bypass, and a treble cut at the end of the circuit that ?warms up? the tone and provides a midrange emphasis.
This kit contains the PCB and all necessary parts. The enclosure can be selected, please select 4 knobs, up to 20mm diameter, for 6,3mm shaft separately.
