I need cheap but nice, warm reverb. I like ambient, but I need more space for fingerstyle on telecaster.
Which one do You recommend?
Or maybe something different?
Take your whole rig to the music store. I'm not a fan of the center, but they have the widest selection. Try all the pedals and decide which one you like the best. Try not to use anything of theirs other than the reverb pedals including cables, guitars etc. Don't be afraid to try pedals out of your price range just so you can hear the difference between them and the ones you can afford. It helps in the decision making process.
My favorite reverb is the fender amp reverb. I think most pedals are trying to get back to that. I also like electro harmonix reverb. Doubt they're cheap tho.
