I just brought home the ZW-44...HOOooLY ****!! This thing rocks out hard!! I'm very excited over the crunchy, creamy, chunky, harmonically driven tone, I just heard come out of my Recto.
I kept my regular settings and lowered the gain to 1 oclock and kicked in the ZW-44 and it definitely boosted me up to a new level. I wouldn't use it all the time becuase I'd get sick of the tone, but if you've got a F-30, I'd say this pedal would definitely pout a smile on your face. Just make sure you don't run it on clean, crank the distortion as much as you can without getting muddy and then pump in the 44!!
Only recommedation is to get a Noise Gate or supressor, because this pedal is pretty hot and noisy!!
Go for it!!
