How to set up foot switch in order

Personally I recommend the following set up:

Distortion>Effects>Compression/Noisegates/Sustain

This will ensure that the signal won't have any odd hiccups due to an odd pedal setup. But if you play around with different orders, you can end up with some very interested sounds.

Heres common order for all pedals tuners, wah, compressors, drive pedals, modulations, time based effects.
Some people like splitting the chain of at the modulation and time effects and run them through the effects loops.
Im betting your going to be using that ds1 pedal a lot more than your metal zone?

I'd start with:
Guitar-Distortion-MetalZone-Chorus-Compressor-Amp

If I use my compressor more for sustain than 'squish' I usually prefer it last in the chain... unless I'm using a delay. Then is sustained the other effects more naturally to my ear.
Then again. Sometimes I'm not looking for a 'more natural' tone.

I like to put the compressor pedal first, so I get a nice fat signal to send through the rest of the chain for processing.

Personally, I like to have all "tone effects", such as wahs, distortions and equalizers in front of "time effects" such as phasers, chorus, flangers and delays. See my set up in the photo. Guitar input is from right to left, starting with the wah pedal.
