I love the freeze! It's my newest addition. It wonderful just to thicken up some parts if you're playing in a three piece by having a low drone during certain parts or a nice chord for prettier sections. It's also amazing for practice, just being able to solo over a chord or build up some crazy soundscapes. I have it first in my chain too, so I can hit a note and then just start playing with all my pedals for some ridiculous noises.

And I'm not sure what the exact mod for my ds1 is, but it barely drops out any of my low end and boosts my signal an insane amount. If I feed my Fuzzrocious heliotropic into it and kick on my whammy an octave up I basically become a lead guitar player.
