Guitar based music, like guitarists, is/are fading away. I'm thinking there'll be lots of gear for sale soon as the boomers die, and few millennials are interested; with few exceptions, this "classic" "vintage" gear is going to sell for pennies on the dollar. I have a few guitars I hope will stay in the family after I'm gone but it won't matter at that point. I'm sure I won't get half what I paid for my gear back.
I made the switch to modelers several years ago, I still have a few tube amps but they're a PITA to sell. I revamped my guitar and bass rigs last year (Boss GT-100, GT-001, GP-10 and SY-300 for guitar; Zoom B1on for bass).
Between the lack of interest in guitar / guitar based music compared to '50s - early / mid '90s, and digital modeling I think the music equipment industry has to see a smaller future...right now they are capitalizing on the boomers, gen-x'ers, and a small number of millennials who care about guitar, especially electric guitar. I think electric guitar virtuosity and technical prowess are dead / dying arts, these skills are valued by few tweens, teens, 20 somethings compared to the past, and the current music reflects this, especially pop music.
Now, add the digital modeling to this current situation I think tube amps sales will decline after the boomers. Who still makes tubes? How much demand is needed to keep them making tubes? At what point will the price of new tubes get so expensive they're no longer affordable?
This ain't the 20th century anymore, that was the guitar's century
I just got a new pointy guitar, but I also got a new wireless MIDI controller "keytar" and I've been working on electronic music since last Thanksgiving, I'm having a blast. I've already been asked to perform at a few local bars when I talk about my electronic rig (and show a picture of it ) LOL, I'll take them up on it when I think I'm ready. I have about 3 songs I'm refining just using my Roland JD-Xi, and I'm still learning my Roland Aira system; I plan to combine these into a single rig.
My new keytar, which will be part of my Ableton Live / Push 2 / laptop rig:
