The 2023 version of the Current Lover has a new layout and new functionality. Whereas the
previous versions were limited to 9 or 12v operation and the MN3007 BBD, the 2023 ed. allows for
up to 18v operation (15v regulated) and a choice of MN3007, MN3207 or v3207 BBDs. Other minor
circuit tweaks have been made.
RATE - Flanger speed.
RANGE - In Auto mode, this is the flanger depth control. In Matrix mode, it controls the notch
point of the filter.
FDBK - Sets the amount of signal sent back to the flanger circuit input.
VOL - Effect output volume.
FILTER - This switch toggles between automatic (left pos.) and manual (right pos.) modes for
the flanger.
BIAS - This trimmer sets the bias point of the BBD.
CLOCK - Sets the clock range from the LFO to the BBD.
LIMIT - This trimmer is used to limit the FDBK control so it doesn't go into self-oscillation.
Terms of Use:
You are free to use purchased CurrentLover circuit boards for both DIY and small commercial operations. You may not
offer CurrentLover PCBs for resale or as part of a "kit" in a commercial fashion. Peer to peer re-sale is fine, though.
