Since boosts have come up, if I'm able to run it where i like it i don't use an OD. Just a wah and phase 90 out front. I do like a little ambience from time to time so I've been experimenting with either my Dunlop Echoplex and Preamp copy out front or my TCE Flashback X4 Delay in the loop. I'm getting to where I more prefer the X4 in the loop. Keeps the front end cleaner.
