Overview
The Pearl FG-01 was a lesser known contemporary of some of the 1980’s compact anger pedals
like the Boss BF-2 or DOD FX-75. Design-wise it is familiar and you will nd 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.
Controls
• RATE - Modulation speed.
• MANUAL - The MANUAL control has some eect 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 anger 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
oer Kingmaker PCBs for resale or as part of a “kit” in a commercial fashion. Peer to peer re-sale is ne, 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 benet.

Notes Kingmaker
madbeanpedals
The Kingmaker allows for two dierent versions of the BBD and clock.
MN3007 BBD and MN3101 clock
You can use NOS chips for both or the NOS MN3101 and Xvive remake of the 3007 (there are no current
production remakes of the MN3101 clock).
3207 BBD and 3102 clock
Any manufacturer of these can be used and even mixed with one another. You can use MN3207, MN3102,
v3207, v3102, BL3207 or BL3102. I used the BL versions for my build. The only caveat is you cannot use
the 3102 clock with an MN3QA007 or a 3207 BBD with an MN3101 clock.
The Kingmaker PCB has two jumpers you need to set according to which BBD and clock you are using.
The jumper spots are located next to R22 and R23. You can solder the jumpers directly to the PCB or use
sockets (in case you ever want to try the other combo later).
Quickstart Calibration
Potentiometers
SPEED and MANUAL @25%
DEPTH and FDBK @ 50%
Trimmers
T3 @ 0% (full CCW)
T2 @ 25%
BIAS, T1 @ 50%
With the eect on and audio feed through the circuit you should hear some anging with the settings above.
Adjust the BIAS trimmer until you get the cleanest audio output possible. It should be right around the 50%
mark but you may have to tweak the position slightly.
T1 adjusts the clock frequency range. As you turn CCW, the LFO will become stronger but more
asymmetrical. When turned CW, the anging eect will shallow out. I found the right setting to be just about
50%, luckily.
Turning T2 CW will increase the range of the DEPTH control. However, I found it worked best at around 25%
to keep in balance with the FDBK and MANUAL controls.
T3 acts as a limit on the FDBK control. With T3 CCW, turn FDBK all the way up. Leave DEPTH at full and
SPEED about 1/3rd or so. Slowly adjust T3 clockwise until you get self-oscillation. Back T3 o just a bit to
eliminate it. Now your FDBK control has the most range possible without oscillation.

The input and output jacks are placed together to keep them as far away from the LFO/
Speed knob as possible.
