GCX no fx sound... just clean guitar sound...

Post by poptart »

I'm in the process of re-doing my rig.. I checked to see if the problem was bad cables.. all of them were good.. my only guess is that there's a problem with the GCX..

When controlling with the Liquid Foot, the front lights light up when called up and I can hear clean guitar sound but the delay effect does not come out... I tried hooking up the delays to my other GCX and everything works well... so the delay works... What could be the problem?

Thanks!
Helena

Found the problem! (so I hope.....)

the GCX that had this problem was the GCX #3. I had the #3 chip installed that I got from Voodoo Lab.. when I changed back to the original chip, the delays worked!

I guess I'll call Voodoo Lab on monday to see if I can get a replacement chip #3?

I think what you mean is that you would want a replacement #1 chip... the standard chip that originally was in the GCX. Give us a call or write to info@voodoolab.com for ordering the chip you need.

By the way, the #3 chip will only change the Control Change messages that the GCX responds to. Control Change messages 64-71(Latching) 96-103(Momentary) on MIDI Channel 16 is what you should program your controller to send if you have the #3 chip installed.

Thanks John! It works now!! :-) the problem was that I was using the 96-103.. as soon as I changed to 64-71 everything worked!!
