All user reviews of 4/5 for the Voodoo Lab GCX Audio Switcher

Used between 2005 and 2008 primarily to reduce the amount deployments cables on stage (only need to connect the guitar jack and take MIDI cable). I have the older model, before this is done (probably acquired) by voodoo labs.

I had nobels before, and I tested the line 6 less well, the sound is much altered with the bypass of the GCX.

What is significant is the transparency of sound looper and the fact that the switch does not create a "click" or other noise artifact. At home or in the studio means a slight alteration of the sound from a direct wiring to other instruments that play is therefore undetectable enough.
Installed with patch cables the right size, good quality and colors with logic something readable understand and own is obtained in a rack. Easy to take several months later when changing hardware.

Being able to switch channels on the amp along with the effects that changes its clean (all cuts at the same time).
Be careful though with echo / reverberations and delays, the looper does not support the release of the signal as it cut the loop so it may not sound very natural. This is the main limitation of this type of gear I think. It forced him to have full effect of delay, reverb etc. effects in the same module (a TC electronics for me) which is the only way to have smooth transitions between sounds.

At the time not much better on the market for the price, the hardware is reliable and meets my equipment around so yes I do it again this choice.

I used it with a pedal behringer twelve o'clock (I did not use all the loops so the little ctrl managed exchange enough) and patch cables GEORGEL (modular regrooved, highly transparent sound level, ideal for a looper) .

The main hardship About the setting of the South, it's not very ergonomic and the absence (at the time anyway) software to do this made the tedious process.

The GCX is a good quality router, there are better options available but they are way more expensive.

The GCX has 8 loops, each one has a input-output and a send-return. This will allow you to do more than just looping/racking pedals or fx. The loops can also be used as switches e.g. to switch channels on your amp. You can also use them to a/b between amps or preamps.

The way to connect your GCX highly depends on how you want to use it, however, the manual is very well written and clear so you shouldn't have a problem hooking it up. On the front panel, you have 2 inputs that can be used as feed thrus. There are a couple of different versions available, some older GCXs had a guitar input, this one could only be used front-to-back. The input on the right has a buffer, which you may or may not like, if you don't, you can plug straight into loop1 or use the other feed thru. If you want to use it to loop pedals, you will need a number of short cables to patch from 1 loop to the other. Some people are modding their GCX internally so they don't need the short cables but this way, you can no longer use the loops for switching or a/b-functions. I always ran mine with pedals sitting on a shelf, 6-7 of them and this worked flawlessly.

The GCX only responds to Midi CC commands so you will need a midi-controller that can send sufficient CCs and preferably has instant access switches. You don’t have to buy the Ground Control pro but the 2 units were made for each other. I used the GCX with a Rocktron All Access and that works fine too.

Price/quality wise, the GCX is really good. Not to many options out there so choose the one you want, the GCX gets recommended and is used by a lot of people.
