Overview

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.

Controls

•  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.

Technical assistance

 for your build(s) is available via the 

madbeanpedals forum

. Please go there rather than emailing me for 

assistance on builds. This is because (1) I’m not always available to respond via email in a timely and continuous manner, and (2) 

posting technical problems and solutions in the forum creates a record from which other members may benefit.
