BA662 Clown (BA662 clone with DC offset trim)

This is a modified version of Guest's excellent BA662 clone with the DC offset trimmer and resistor (aka declick mod) so you can drop it right in, trim off the thump and enjoy your BA662ness. Boards are $1.55 for 3 and parts come to all of $8.

Nice. What's the impact of the trim? Slower?

Trims off the DC offset so you dont get the VCA thump

Interesting. Just listened to some example and I hear what you're talking about.

Do you have a BOM? Otherwise will track down the Open Music Labs. Curious what trimmer you're using though.

Thanks!
