Chip, thanks for your additions.
I actually just last night saw you had a mod on your site for making the mg delay actually zero. Very cool. I had posted a comment but since we are here... Is it really as simple as swapping out the one resistor for another? That's all that'd entailed? I'm still a bit new to schematics but comfortable learning.
I will check out these other mods too. Thanks very much. Extended bass is enticing.
And yeah, losing the MG->VCA sucks. I was actually thinking there might be a way to get it pre effects board somehow. But that sounds rather adventurous :)
