Phase 90 pedal - in front of amp or in effects loop??

I have no experience w/ effects loops as I have only used amps w/o them, but I have noticed that unlike most other effects I use (which in my case are just delay, Trem, and "Fake Leslie"), I found my Phase 90 did sound better before my OD pedals. Don't know if this helps...

 

Agreed. I run mine in front of the amp and before the OD & distortion.

 

Personally I like to have any modulation pedals, whether they be flange/chorus/phaser directly after the distortion and before anything else like delay or reverb. The phase 90 is an interesting case though cause depending on which version you have it may unintentionally produce a fairly big volume boost. I know that mine does this and it can be sort of a problem at times, but luckily I'm using the phaser mostly for solos where the boost can help.

 

The tonal difference between putting a pedal in the effects loop and putting it into the front of the amp has never been worth the extra hassle of cabling and setup for me. It might be worth it if you're running a delay pedal into a dimed dual rectifier and the amp is eating the echo. Other than that, try it yourself and see. Trust your ear.

 

Effects loops are for wimps.

I run my Foxx Foot Phase before dirt.
