thank you!

you’re welcome, man. just ask if you encounter difficulties...

hi VeeVeeVee!

1. the cable lenght for the jumpers is about 8cm.
2. the rack case I got from germany, it’s a chinese custom made one. the rack drawers are also from germany, from adam hall (I suppose they are also chinese made)
3. yes, this is the way of doing it. I first solder the connector that goes in the GCX and then pull the cable thru the rack from the pedal on the drawer to the lateral wall of the rack then to the GCX and add some more just to be sure there won’t be extra tension on the cable. pay attention to the margins of the sides of the drawers - they cut like a knife and will destroy cables that slide along them...
4. sorry, don’t know the weight. it was pretty heavy but this was of no concern to my client - he always has techs that carry it on and off stage.

don’t exactly get what you are saying about securing the pedals. I suppose you use some velcro to fix the pedals on the drawers! if not, you should...
if you mean the drawers sliding out when you shift the rack, the simplest solution (if the drawers don’t have a locking system) is to mount a piece of foam on the inner side of the front cover that closes the rack. this way it will press on the drawers and not let them slide...

man, it depends... you can have ground noise in some configurations and sometimes using the gcx buffered input can help (it connects the circuit to the gcx ground). you just have to try...

that’s because I used the input buffer on the first gcx and the input signal comes at the rear of the unit, so it must be wired to the front to go to the buffered input.

sorry labana, have no time to do a schematic for the routing, but all is very simple - all the pedals are in series. plus the midi circuit, which controls the 2 gcx, the lehle switcher on the pedalboard, the whammy and the delay. the main concern was the ground loop noises and this was solved by using transformers to galvanic separate the gcx units from the rest of the circuit.

hi guys! it seems that the only way to resolve some of those issues is by galvanic separation at the input and output of the problematic units. this means you have to use some kind of audio transformer that separates the ground of the units in relation to the ground of the other circuits. it works flawlessly!

this one was in a concert hall, but I also perform in clubs and bigger open-air stages.

thank you!

and please, don't use those unsoldered cables if you want quality...

oh *, john, you mean he screwed the pedals on the shelf???? that's a no no!
