Caesar Chorus Bass Mod

[Anthonyj]

I Couldn't find this so I figured I would add it. please tell me if I was wrong.

I was on Aion Fx's site and came across the Azure chorus thinking it might be fun since it was based on the CE-2. In the instructions he mentions that between the CE-2 and CE-2b the only difference other than a Mix knob is a single capacitor value. I remembered that I already built and use the Ceasar Chorus which is a Juilia which itself is based on the CE-2. Both of the schematics lined up, so it was easy to find what to change.

The change is C17 from 33nf to 12nf.

This change will limit the low-end frequencies that are modulated in the circuit and keep the bass from disappearing when the pedal is engaged.

I built a little board around a SPDT switch I had laying around to change the values back and forth to mess with it.

COOL!

Thanks for the tip.

Not only do the schematics match up, so does the REFDES: Aion C17 = PPCB C17 !

Easy-peasy.




Which do you prefer the 33n or 12n...
BASS?
GUITAR?

So far I prefer the 12n as it keep the low end intact for my bass, I haven't tried it on guitar yet.

Thanks Anthonyj.

I'm thinking of whether or not I'll put C17 on a toggle; I don't really play guitar much, mainly using it on bass — but if there's a substantial enough difference.

I've got a brown Boss CE-2B, and while the guitar sounds good through it, I've never had the opportunity to A/B it with the guitar version.
