Re: Which first-chorus/distortion
I like to run the wah, then the OD's from highest gain to lowest gain, then the modulation FX....even better if the last one in the chain is stereo, so you can run out to 2 amps.
It's partially unimportant to me, because I rarely use OD gain when using modulation FX....except maybe delay. I like that stuff for clean tones mostly anyway.
