How can you not love this.

Comments about Voodoo Lab GCX Guitar Audio Switcher:

This thing is awesome. It works flawlessy pulling out pedals out of the loop. Doesent drain any tone and adds true bypass to all your pedals. Its a must have.
This things built to last. plus comes with a 5 year warranty.
Its a bit expensive but it solves a huge issue that i myself and many other guitar players face. So its well worth the money. Plus it seems of good quality.

Incredible for integrating a complex set up

By tom-J1AjT

from Undisclosed

Comments about Voodoo Lab GCX Guitar Audio Switcher:

In the end I rely heavily on this unit, and have been completly satisfied. It has met all my needs and enabled me to streamline my rig greatly. Voodoo labs smaller pedal version of this unit may be a better value for individuals that don't need as many loops. I hope that one day voodoo labs offers a second version of the GCX that supplies power, is color coated for trouble shooting, and offers channel linking.
8 independent loops allow effects an processors to be switched out in real time, perform channel switching, or rout between preamps. I use loop one as a kill switch (and to tune silently, via the second out put of the buffered input). loops 2 &3 for each channel of a dbx compressor; switching between lead and rhythm compression. Loop 4 for a boss octave effect (which does load down the signal slightly when bypassed). Loop 7&8 are used to switch between presence 1&2 and volume 1&2 on an engl 540/50. All this plus multieffect processors are controlled via the ground control pro with an easy setup time and flawless integration.
I do wish that the loops were color coded for quich trouble shooting (i used colorful electric tape). I would have liked to have seen a swich to link channels to avoid using jumper cables. And a Built in power supply could prove valuable to people more pedal oriented then me.
I have also used this unit to switch between inputs of a dual rec and a Peavy JSX, as well as swich function on the dual rec flawlessly.
I have had absolutely no problems with this unit in 4 years of use. Voodoo labs tech support is incredible and they demonstrate a myriad of complex set ups on their website.
Even with repeated pluging and unplugging of cords i have yet tohave a jack go bad. The power supply is robust but fits on a monster power conditioner easily.
Since the Jacks are gold I used mogami gold cables for better conductence and intend to have the rest of my input and output jacks switched to gold later.
The only reson that this unit does not get a ten in this department is i wished that they would have included a way to link channels instead of having to use a jumper cable via a switch. I also would like to have seen a some form of powersupply built in like on the TC electronics G-system.
For its price & features it is an awsome value and outstanding tool for complex or even just simpilifying a rig that already uses MIDI.

Pro Quality Rigs no matter what you own!!

By xx_God_of_Rock_xx

from SJ, CA

Comments about Voodoo Lab GCX Guitar Audio Switcher:

A buddy of mine has one of these plus the ground control pro. GC Pro + GCX = Awesome!!! He has a JVM head as well as a Carvin V3 head and the GCX controls all the channels on Both amps seamlessly. He also a a rack drawer full of various pedals (overdrives, Chorus, Delay, reverb, etc...) And you can switch those in and out on the fly as well. The Ground Control can also be programmed to have any combination of FX and amp Channels in seconds. Just select the channel, and Loops you want active, then go in and write it to memory...That Easy!!! I plan on getting one of these as soon as possible so that I can create my own custom rig with real amps and effects!!!

solid quality good unit

By Mr. magic2000

from new jersey

Comments about Voodoo Lab GCX Guitar Audio Switcher:

Paired with the ground control pro this unit can control everything but the kitchen sink (could probably do that too if you hook it up to one of the loops). Be prepared to buy alot of patch cables to connect the signal path to all your units. Also realize that the buffered signal will change the nature of your gain structure slightly. There is a passive signal path offered as well however there is a drop in signal if you are going through a bunch of stuff (ie the buffered path) This company builds equipment with solid quality and very good designs. I highly recommend this unit in combination with the ground control pro.

Comments about Voodoo Lab GCX Guitar Audio Switcher:

I have been playing in bands with my dad since I was 14....I'm 33 now.I play in two bands these days. One band is an original music band that I play Bass in, and I play guitar in a popular local South Lousisana cover band.My guitar rig is a Hughes & Kettner half-stack and a Gibson SG. I had previously used lots of stompboxes and the the two channels of a Boss Line Selector for all my effects...old school way, i guess, butWAY too much footwork. I still had to switch the amp channel too on a seperate foot switch...not to mention the Wah!!! The Audio Switcher and it's Ground Control Pro allows me to still use all my favorite stompboxes and switch them via MIDI, and I can switch amp channels too! The GCX ties it ALL in to one funtional, easy to use rack mountable set-up and one footcontroller does basically EVERYTHING!!!! I only rated 4.5 on features cause it didn't have an expression pedal.I looked into the G Force, but the price was a bit outta the range I can afford in this economy. For almost $2000 less, I got an adaptable MIDI switching unit that fits my rig like a glove! It more than suits all my needs!Now you see why many professional musicians use this as the centerpiece of their own rigs!I don't know why you'd build your guitar rig without it!!


Gcx Switcher

By Bailey-tlF3L

from Phoenix, AZ

Comments about Voodoo Lab GCX Guitar Audio Switcher:

This unit works extremely well for running effects and multiple amps. Use of the ground control pro is highly recommended. The only drawback I found was when you run two amps digital music suggests that you use a y cable, which lowers the impedence. Result is a loss in tone and a lot less volume. I suggest using an active splitter or a passive splitter that can transform impedence levels properly. I had to build my own.


The Best Thing Since Cold Beer!!!

By Killingelmo1

from shreveport, LA

Comments about Voodoo Lab GCX Guitar Audio Switcher:

The VooDoo Labs GCX is the greatest invention since the creation of cold beer! This piece of equipment allows a musician to change the effects in his rack and also the channel on his amp head with the push of a button. Literally, if you purchase the Ground Control Pro you can change everything that is MIDI controlled with one button. The GCX is easy to use and is very strait forward. I have never been happier with a piece of equipment. This GCX and Ground Control is not just for people that have all rack mounted equipment; a rack is required (obviously) to house the GCX, but it can be used to turn on and off stomp boxes and also an A/B switcher for two amplifiers. As a matter of fact, the only thing the GCX and Ground Control Pro can not do is???get you a cold beer! So, if you are like me and want to have all of your; effects, amp selection, stomp boxes, whammy pedal or any thing else available with the push of a button go pick up the GCX and Ground Control Pro as soon as possible!
