Guitar for me. And ironically it was also Green Day's 'When I Come Around' that really got me into it. Specifically the Woodstock '94 performance.
Jackson Dinky is my go to electric. Even has flames on the fretboard
Also have a cheap black electric I bought for working in camp, don't even know the brand. I never play it.
A couple acoustic guitars too, Washburn and a Yamaha.
I'm self taught (along with the help of Guitar World in the 90's and now UltimateGuitar) and am decent enough. Started doing vocals simultaneously a few years ago and wow is that ever hard. But through practice I've gotten pretty decent.
I like to do an acoustic rendition of Square Hammer but it seems my group of friends dont really know who Ghost is
