I have 2 amps, a Digitech GSP1101 preamp with cab emulation to board and 2 gcx audio switchers from voodoo labs as well as a ground control pro pedal. I may already have what I need but I am not sure if it is all I need for my odd application.....
I need to play both amps at once or
I need to play one amp and reamp to the other via my laptop (I am already familiar with reamping)or
I need to reamp 1 from laptop signal to both amps
or play the 2 amps myself and reamp from the laptop to my digitech GSP1101
I want all of these options but can make due without using the Digitech if I have to.
I have been racking my brain trying different routings with no luck and alot of ground hum lol. If anyone has a gcx worksheet that explains the way to route this scenario I would be ever so gratefull and will send you a crappy cd of my band to add to your problems lol.
(gcx) 2 amps + gsp1101 played by 1 gtr & reamp same time
Re: (gcx) 2 amps + gsp1101 played by 1 gtr & reamp same time
This is a little tricky I suppose. You will need some isolation transformers in order to get everything to play nicely together. Is everything ultimately driven by the same guitar?

Re: (gcx) 2 amps + gsp1101 played by 1 gtr & reamp same time
I don't need to route the gsp1101 to my amp as its output only goes to my monitors and foh. We can treat it as a seperate amp called (c).
Either 1 guitar to 3 outputs (amps a / b / c)
reamp to 3 outputs. (amps a / b / c)
guitar to amp a. / reamp to amp b & c
guitar to amp a & b / reamp to c
guitar to amp a & c / reamp to b
Either 1 guitar to 3 outputs (amps a / b / c)
reamp to 3 outputs. (amps a / b / c)
guitar to amp a. / reamp to amp b & c
guitar to amp a & b / reamp to c
guitar to amp a & c / reamp to b
Re: (gcx) 2 amps + gsp1101 played by 1 gtr & reamp same time
Here is a setup to try out. This will require two 3 way split cables, or two daisy chain cables.
Run the Guitar to the Guitar In on the front of the GCX, then run a daisy chain cable from the Guitar Out to the Inputs of three GCX Loops.
Run the output of the Laptop to the front panel Feedthru on the GCX, then run a second daisy chain cable from the rear panel Feedthru to the Returns of the same three GCX Loops.
Run the outputs of these three GCX loops to your three "amplifiers".
This should let you select the source signal independently for each amplifier. Follow the above connections and let us know what happens.

Re: (gcx) 2 amps + gsp1101 played by 1 gtr & reamp same time
I will try it thanks. I am not sure what a daisy chain cable is? Are y cords the same thing? Will I need iso transformers like the lehle p split? If so how many? I have an ebtech hum eliminator if that will work. Thanks for your time and help.
Re: (gcx) 2 amps + gsp1101 played by 1 gtr & reamp same time
You need a way to split a single output into three different inputs, a 3 way splitter or a daisy chain cable would be suitable. These are custom made cables and will not be found hanging on the wall in any music store.
As I mentioned before, you will likely need to use Isolation transformers, however we are starting without them in order to have a better idea of where they will be needed once this is assembled. Likely you will be able to get away with using the Hum Eliminator before the inputs of both of the real amplifiers but I opted to keep things as simple as possible for testing purposes.

Re: (gcx) 2 amps + gsp1101 played by 1 gtr & reamp same time
Can I use 2 mono (1 male - 2 female) per side One plugged into on half of each y cord to get 3 outputs to the 3 gcx channels? Where can I buy these daisy chain cables? I only see power and computer daisy chain cables online. Would 2 aby boxes work? I have a rapco ab-100 that acts as an aby. Thanks
Re: (gcx) 2 amps + gsp1101 played by 1 gtr & reamp same time
You can link two Y cables or two A/B/Y boxes in "Y" Mode for testing purposes, but a daisy chain cable is ultimately what you will want to use once this is being set up for actual road use.
Again, a 3 way split or daisy chain cable is going to have to be custom made, you will not find a picture of one...
...except for right here!!!
A local shop that does electronic repairs, or any friend that is handy with a soldering iron would likely be able to whip this up quite easily for you once the time comes. Likely any number of the online custom cable makers will be able to do this too, but you will have to contact them with your request as it is unlikely to be popular enough to warrant any mention of it on their respective websites.

Re: (gcx) 2 amps + gsp1101 played by 1 gtr & reamp same time
Thanks so much. I just made a trip to guitar center so I will have this working within a few hours. One question: Do you have a picture of the cable where they connect without the sleeve? I could make this cable myself but need to see how its soldered. I would think the positives just get twisted and soldered but not sure if the neutrik ends I have will accomodate the size of the wire when combined? Thanks again.
Re: (gcx) 2 amps + gsp1101 played by 1 gtr & reamp same time
Ok. it works!
The routing is perfect but the hum is unbearable. I tried the ebtechs and I thought they would help but did not get rid of the hum and may have contributed? The hum eliminator seemed to be working in the setup I had before with 1 input into the gcx front buffered input then out of the back as a Y. The hum eliminator sucks tone and signal big time. When running it on the reamped channel it almost cuts the gain in half. (Little or no hum with gtr to 3 amps only)
In attempts to minimize or kill the buzzing I tried both of my stereo hum eliminators at the same time:
(out of the 2 gcx outputs into a/b of the hum eliminator then out to the 2 amps)
&
(from the feed thru backside into the side a of the hum eliminator)
(from the guitar out backside into side b of the hum eliminator)
I also have another gcx (older buffered on both inputs) I did notice more hum trying the 2nd gcx inputs with corresponding backside outs although I suspect if I use the older inputs the buffer would help my signal. Less hum when using the same gcx units front inputs ( laptop = feed thru in) (gtr signal = gtr in)
The hum is less when one of the laptop y cord sleeve jacks metal touched the guitar signal jack of the guitars signal near the ebtech? The hum gets way worse when I touch any gtr plug sleeve on the backside of the rack that has to do with the signals with my fingers though.
The 3 guitar split has little to no buzz when played together (1 guitar - 3 amps)
When the laptop signal is introduced is when the buzzing starts
I tried 2 different types of y cords and y adaptors (type without cable - one unit with 1 male 2 female holes) and a few regular mono 1 male 2 female y cords) NOT MUCH DIFFERENCE BETWEEN THEM except the y cords would touch other cords and the hum would be less sometimes until the cable moved? (UNRELIABLE)
I tried putting the hum eliminator before the gcx front inputs on either and both of the signals with no difference made except a more static like hum at the same unbearable volume.
In summary:
I see I need something to get rid of the hum from the laptop rig (which also includes a mixer / power amp / compressor / profire2626 interface etc) Would a Lehle p split or more than one work? If so where should I put it / them in the signal chain? Thanks a million John WE ARE ALMOST THERE!
