I'm finding delay -> reverb works best as well. I just got both pedals the last few days so it's all new to me.
I got a Biyang AD-8 delay - 2 chip model (600ms - 1100ms) and goes from echoplex / slapback to bottomless pit. Gets a great Led Zep 2 vibe
Just got the BOSS FRV'63 -1 reverb. very cool, but I need to learn how to dial it in still
Thanks
