Be careful! As mentioned in a pedal post I was in a while back, those pedals multiply like rabbits! Never get one even close to damp or poof! You have a dozen over night!
Or you can buy one big huge monster Flemmish Giant Rabbit called a Helix.
I played through one a few times. They open up a Pandora's box of possibilities!
If you play alone get an I-Rig and run it through an I-phone (garage band or Ampli-tube) into your Marshall. That will open another door as well at minimal cost.
Number one rule! Have fun!
