Boss CH-1: Depth Mod?

[Bucksears]

Per the schematic above, has anyone ever increased the value of C10 (across pins 5 & 7 on the MN3101) to add more depth?
This is apparently a popular mod for the (analog) CE-5, so in theory, the same could apply here. I've always heard that the CH-1 sounds amazing, but is more subtle than others.

I have upcoming etchable, single-side layouts for the analog CE-5 and CH-1; they have the switching portion of the circuit omitted. Once they are done/built/confirmed, I'll share the layouts with anyone interested. They are designed for a 125-B enclosure.

Hey. I have not made the change you suggested in the CE-1 but I have in pretty much every other chorus that I have made. I love putting this capacitor on a swtich to get low, medium and high depths.

hello,

i modded my CH-1, vibrato, depth, etc. I found the mods on facebook's boss modding group.

I'm happy with the results. Only one issue i couldnt fix, it was already there in the stock version : some white noises when the EQ is on high values.

It's a great chorus, i still use MXR stereo chorus more, but CH-1 is not bad at all.

It's suggested in the Wampler mods book that you change the value to 100 or 200pf on the CH1

I downloaded the book years ago from his site when he made it available and have just uploaded them to my drive again the CH1, CE2 and CE3 mods are in part 2 in case you don't have them:
