« Good router/switcher for our rack »Published on 04/01/11 at 02:28
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.
