Explanation of Weird Title. Younger players new to the game may want to wait this one out. Not that they have to. If they've already found an effect pedal that meets the criteria go right ahead and join in. Most long term guitarists who like to use effect pedals, over time, come to recognize specific models by specific brand they would never want to be without. This doesn't mean they won't have other examples of that effect they use now and then. It just means they've found one they would never have unavailable to them. A true must have fully working in good condition example that's always ready to be utilized. Whether you own 5 pedals or 50 pedals ..... if someone offered you a lifetime supply of a specific effect type, in a specific version / incarnation made by a specific brand or builder that you already currently own and never want to be without, (because what it does is integral to your own special tone or whatever), what would you ask for a lifetime supply of? I know many guitarists who own pedals they would never want to be without. Eric Johnson's specific Fuzz Face version he's used forever. During his short life Jimi's reliance on his specific univibe. David Gilmour's need for the availability of a specific Binson Echorec. Is their a Chorus effect lover out there who's found the exact chorus pedal they would never want to be without? A Flanger or Phaser user who's found his personal best of the best? A guitarist who relies on a specific effect pedals Smooth Gain or Crunch for their personal rhythm or lead gain tone? God's gift to you in the form of a Wah WAh, Harmonizer, Octave, Tremolo, Vibrato, Reverb, Delay / Echo, etc., etc.. If you've experimented enough and played enough and gone through X number of effect pedal examples to have found the one that you cannot imagine not having on your pedal board ....... What is it? What would you ask for a lifetime supply of? If you have more than one effect type you've settled on go ahead and list them. I'm personally set on a handful I would never want to go without but I've been playing for 60 years come October of 2021. That's why I mentioned the young players up front. There's still a lot in their future that I could ever imagine. Then again ..... if you think you're set ..... list them.
