Between flanger, phaser, and chorus. I know some people swear by putting phaser or flanger in front of their dirt. But for me, with an MXR Micro Flanger, it was just too subtle in front of my dirt pedals. I just obtained an MXR Phase 95, and currently have after dirt with my flanger. They’re both going into front of amp, which I do have on the dirty channel, but with low gain. And my chorus is in the loop along with delay and tremolo.
Thanks @WholeLottaButtStuff (do you play bass? lots of bottom end there). I noticed the phaser is much more prominent than the flanger, both before and after dirt. Could just be from my choice of pedals! I found the flanger way too subtle before dirt. The phaser was still noticeable before dirt, and I could work with it (like if I were in a band and covering a song I’d want to order more like what the original player did), but just for at home noodling right now I like it slapping harder after. I think if I ever get back into a band I’m going to have to go for a loop switcher so I can setup playlist banks.
I do play both bass and guitar… but I’ve never actually used phaser with bass, so I can’t really comment on what would work best it.
When I comes to bass effects, I like filter type effects, but that’s pretty much it.
