All about modern commercial stompbox circuits from Electro Harmonix over MXR, Boss and Ibanez into the nineties.

Ibanez - RC-99 Rotary Chorus  [schematic]

Postby Dirk_Hendrik » 19 Dec 2007, 16:17

For component values I cannot make confirmations as all is on quick notes and some scans made over a year ago. As for the schematic I could check and re-check for possible errors. However, whatever I will do, AG will pick out a few more. Let's say I'm lazy and will just wait :lol:

Thanks for the schematic...

Hmm... But I am lazy too.... :lol: and didn´t already trace it... I even haven´t had one in my hands or seen some guts... so this time you have to look for yourself for errors... :lol:

No prob ;)

I'll try to dump the PCB layout online next week. That will give the ones who do have a Christmas holiday something on their hands.

ther than that,
I did build that PCB with the component values displayed here. If I have made errors at the time it doesn't mean the thing doesn't worlk.

Note needs to be taken that a lot of this schematic could just be taken from the Ibanez SC10 chorus. They're definitely cousins.

The clock circuit around the MN3102 is identical to the CS5.

The "big difference" is only the use of a compander instead of pre/de-emphasis like in the SC10 or CS5.

It´s a chorus.... there is not much new to invent.... except a good sounding name...: "Rotary Chorus"

Locobox also had a "Rotary Phaser".... And I also couldn´t find anything "rotating"... :roll:

Nice, that's one I've always liked. I agree there's nothing "rotating" in it, but just a nice chorus (and I don't usually like'em at all).

This is true. If you are ok with that, DH?
Just let me know and I'll move it there.

Well, since I put the layouts together with the stuff the project is quite "do-able" for the more experienced pedalpushers. I'd say, go right ahead :wink:

Did anyone actually do a clone of this one????? Looks like a great pedal thinking about doing one for myself. Dirk you do the best schematics i have ever seen in forums.

if anybody has built this chorus - can I substitute the 2 SA 1015 with an BC 558B? Can anybody give values to calibration??
I will have/built this chorus :wink:
How can give some gutshoots?

Yes you can.

Yes. I have built this one years back.

Hey Dirk is there a track side pic of this somewhere i could get my hands on or is there possibly one on the way. Would be interesting to see some guts shots of the original on this one but i haven't come across any on the net. cheers
