The Pearl FG-01 was a lesser known contemporary of some of the 1980's compact flanger pedals
like the Boss BF-2 or DOD FX-75. Design-wise it is familiar and you will find similar circuit blocks
used in the BF-2 and the MXR.
The FG-01 utilized the MN3207/MN3102 BBD/Clock pair. The Kingmaker project allows you to use
the original chips or the MN3007/MN3101.
• RATE - Modulation speed.
• MANUAL - The MANUAL control has some effect on most DEPTH settings. With the DEPTH
full CCW, the MANUAL control produces ringmod tones. As DEPTH is turned up the MANUAL
control will change the center frequency of the flanger in its normal operation.
• DEPTH - Modulation intensity.
• FDBK - Modulation feedback amount.
• BIAS - This trimmer sets the voltage input bias of the BBD.
• T1 - This trimmer sets the frequency range of the clock.
• T2 - This trimmer sets the max DEPTH setting.
• T3 - This trimmer sets the maximum amount of audio signal that is fed back through the circuit.
Terms of Use: You are free to use purchased Kingmaker circuit boards for both DIY and small commercial operations. You may not
offer Kingmaker 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
