The complete BBD clock archive
- Fender3D
- Cap Cooler
Hello guys,
I hope this is the proper board for this thread
I noticed this great forum lacks the main info about BBD based pedals...
CLOCK.
Heck, we can search for every fuzz face's single node voltage, we have constant requests about "what voltage here and/or there" in workbench board...
but we have few or no info about BBD based pedals clocks.
I think we need an exaustive clocks archive if we wanna properly clone BBD based pedals.
I think max. and min. clock measured @ BBD pins and power supply used should be enough to nail THAT sound or, at least, to estimate delay time.
Please add your suggestions and/or tips.
Thanks.
This might be an example:
MXR Micro flanger:
I powered it with a stabilized power supply @ 9.6V
max clock freq at SAD's pin 1 is 850KHz (@ min rate)
min clock freq at SAD's pin 1 is 133KHz (@ min rate)
I hope this is the proper board for this thread

How easy it would be to add the P/N of the chip to the summing up.

Isn´t normally meant with "P/N" the Part Number (e.g. SAD1024; MN3007) instead of the pin number of the clock driver ?
Just asking....

Ibanez UE400 - first version (1980?) with distortion (not overdrive) and compressor section with CA3080 OTA :
Flanger/Stereo Chorus section with NE571, MN3007, MN3101 :
min. clock 40-45kHz (WIDTH = CCW, SPEED = CCW, FEEDBACK = CCW)
Chorus and Flanger clock is the same

Rockman X100 chorus doubler
LFO 1.7 Hz
Triangle
Stock is 50.6 to 51.6 khz (ratio 1.02)
We modded to 48.9 to 59 kHz (ratio 1.2)
Video has chorus going into the echo reverb built into the X100, so you are not hearing the effect of chorus alone
Thanks to Pedro Yi for the hard work of opening X100, modding it, measuring it, making Video.
