В гугле - How do you rack pedals, how does this work?
Самый содердательный пост:
There are definitely other options out there, but this is the way I recently did it:
I already had all the pedals and a nifty little 1-space sliding rack drawer/shelf, so to complete the rig I bought a used Voodoo Labs (Digital Music Corp) Ground Control and GCX Switching unit from a fellow Gear Page member and a 6-space, Anvil-type shock rack on eBay, altogether about a $500 investment. I bought a shock rack because it's wider than a standard rack, and at 18" high, would also serve as an amp stand.
While the Ground Control comes with it's own power supply, it can also be powered by the GCX, so when used together there is only a single MIDI cable on the floor. The GCX has 8 loops to connect pedals to; if you need more you can control up to 3 more GCX units with the Ground Control.
Each GCX loop has In, Out, Send & Return jacks. You can route the In and Out signals anyway you want, and use the Send/Return jacks to connect your pedals to the individual loops, which may take a little pre-planning to get the optimal configuration. You can also configure a loop to be a Momentary Switch; I use one as a Tap Tempo input with a delay unit.
Once you've figured out the desired signal path, it's really rather simple to connect everything together. You'll need a lot of patch cords, though, of various lengths (I used George L Cables) but you don't need any MIDI knowledge. I'm very pleased with the way everything works. The only downside is, fully loaded (GCX, pedals & power supply), the road case weighs a ton.
