Hello everyone:

I have a 3 channel Dual Rectifier.

I want to hookup my Dual rectifier to my GCX Audio switcher, TC Electronics G-major2, and Ground control pro.

I want to control all of my amps switching with the GCX and ground control pro while using my g-major 2 for all of my effects so I can design banks with specific amp switching and effects.

Basic setup, no stomp boxes just these things.

I have it hooked up this way:

I have a midi cable running from my ground control pro to the GCX to power the ground control pro (it's powered on) I have another Midi cable running from the GCX to the Midi in on the gmajor.

I have followed all instructions and my GCP acknowledges my GCX.

I ran 4 cables from loops 1-4 the "out" hole to the back of the dual rectifier in their respective jacks channel 1 2 3 and solo.

Am I missing something ????

Thanks in advance! Josh

The connections you describe appear correct. Is the amp not responding when activating any one of GCX Loops 1-3, or enabling GCX Loop 4?

Basically, whats the problem you are experiencing here?

I can now switch channels on the dual rectifier using the setup I mentioned and I can get sound from my gmajor2 if I add two additional cables from my fx loop to the g major and back to my return on my effects loops.

However... Now when I switch channels on the dual rec I hear a popping sound. The GCX is changing loops accordingly but the pop is
Obnoxious which makes me think maybe I should just use a Mesa footswitch and forget about switching amp channels w the GCX and the GCP, that pop cannot be normal or good for the Mesa...?

Thoughts?

Try using speaker cables for the channel and solo switching connections to the amp rather than instrument cables.

I hope that helps!

Do you say this bc instrument cables are unbalanced and speaker cable are balanced? Why would that fix the pop? Just curious.. I will try speaker cables.

This is the correct way to make your audio connections. The MIDI cables only carry MIDI control info.


Did the amp pop when using the Mesa footswitch? I've been playing Rectos for almost 12 years now, and they are notorious for popping a few times, and it is worse at lower volumes.

What I do with my Roadster Dual Recto is cycle through all the channels while still in standby, ending on your Orange Channel before coming out of standby (via a Voodoo Labs Control Switcher, virtually the same as using a GCX). This eliminated all pops from the amp at gig volumes.

Also, for all things Mesa Boogie be sure to visit the "Boogie Board" at http://www.forum.grailtone.com. There is a lot of great info there, even on this subject.

Hope this helps.

Speaker cables are not balanced. The difference is that the conductors in the speaker cable are much heavier (thicker).

Audio cables (both balanced and unbalanced) are shielded, speaker cables are not.

Balanced just means that the shield ground is isolated from the audio ground.

Thanks for the advice guys.

I decided after trying to learn to midi map my effects from the g-major 2 to the ground control pro that amp switching w the GCX is not the way to go for me. I like the idea of just using a footswitch to change amp channels. That being said there is really no point for me to keep the GCX I just bought bc I switched to the G-major 2 to run all my effects and do not intend on adding in stomp pedals. So basically I have 8 loops in my rack I will not use. So I listed the 375-400 dollar piece of gear on eBay today, and I plan on just buying a Mesa footswitch 100.00.. It's just easier for me, and the pop is almost non existent w a footswitch compared to the GCX..
Now my next hurdle is learning to make my control pro control my g-major 2 properly. I have read both manuals and have all my effects for my set list created and saved, I just need to learn to midi map everything.
I figured it would be a piece of cake but I am having a * of a time with it! haha
