The XOR'CIST Bill Of Materials (BOM)
•
* These are current limiting resistors for the rate indicator
LED's and the modulation indicator LED. Use the appropriate
value for your LED type. I use 15K resistors in my fully
assembled builds (with superbright LED's).
•
The gate trimpot sets the decay of the ringmodulation carrier
frequency gate. Set the blend fully clockwise and adjust the
trimmer to match the sustain of short notes.
•
The sens trimpot sets the input string sensitivity and a balance
between gate and sustain.
•
The DIP switch has two functions. It can toggle on/off the LFO
gate and set the momentary switch action as either latching or
momentary.
•
Not included in the BOM:
◦
1x bypass LED
◦
1x CLR (current limiting resistor) for the bypass LED
◦
Also not included in the BOM but also good to have:
enclosure, input and output jacks, LED bezels, DC jack,
3PDT bypass switch, knobs.
