This^ haha. Though I'm inclined to agree. I'd like to have a JP handy and could settle in most other areas. The little Yamaha THR series amps are killer for practice as are the latest iPad apps like what Positive Grid offers.Probably my guitar. I can't play guitar without my guitar.
It would definitely be my pedalboard. It's pretty much the core of my sound that I've been working on for a while to get it right. Still need a few things, but my 3 drive pedals, tape delay and strymon BlueSky is a staple that works through any amp you give me and most likely any guitar you put in my hand. Of course having a good guitar is intrinsical so you don't have to fight playing it.
Probably my guitar. I can't play guitar without my guitar.
Seriously though, and this might sound dumb, my guitar pick. I cannot play well without a pick that I really dig. I'm not someone who can just grab any old pick and be happy. I get too distracted by how it feels "wrong". Been loving the Dava jazz tip poly gel picks lately.
