I'm realizing I never returned to post my Spark results. Bottom line: much prefer the Fulltone Fat Boost 1. Despite the hype/advertising, the Spark had a "compressed" sound/feel to me whereas the Fat Boost sounds/feels more "open." Not a knock per se on the Spark - it may be perfect for your app - but wasn't what I was seeking. At this point, having A-B'd in person the Fat Boost 1 with several good boost pedals (or pedals that can be used for a boost), including the Earth Drive, I'm confident the Fat Boost 1 is for me and will not be searching further in this vein.
When we Go to Heaven, will Jer ask whether we were the perfect Jerry ... or whether we were the perfect us?
What does Jerry tone mean to you? Copying Jerry slavishly? Honoring Jer's music no particular way but our own?
We're each of us unique. And also the same. Can we open our hearts and minds to both?
