The amateurs and hobbyists have controlled the market since Day One. All of these companies that cater to that market are more interested in sustaining successful businesses than they are with impressing the internet.
Here's something else that is going to take another piece out of your perception of things: The top selling amps and guitars (you know, the actual numbers on the spreadsheet that keep the ink black instead of red) are all the sub-$1,000 entry to intermediate level gear. That's what generates the primary revenue stream. Marshall sells a shit ton more Origin 20s than they do JCM and 1987 reissues combined. The pros with endorsements are there for marketing, not as a primary revenue source.
The automotive industry worked in much the same way for decades with their factory sponsored race cars. The old saying was "Win on Sunday, sell on Monday." But people weren't buying race prepped stock cars, they were buying the much less expensive street versions.
Interesting take. To quote my old boss at the amp company "if it weren't for amateurs we wouldn't eat".
So yeah I get how the market is controlled by it's target audience. Which is amateurs and weekenders.
The thought its controlled by pros is odd.
Likely comes from the oddball notion small builders put out that there's no free gear, everybody pays.
But what I've seen is this.
When I started playing in bands nearly 5 decades ago we all got used amps. Like sellers, Hiwatts, Marshalls obviously
None if that gave us the gain we wanted so it was treble boosters. Fuzzes, Dist+ and Super Distortion pickups.
And we found guys to hack the Marshalls that we like 200 bucks at the most to hack them.
Most of us didn't have any real bread for gear.
And mostly we had nothing but Gibson or Fender, and if course law suit Ibanez and their early Roadsters.
The price explosion started with Charvel and Jackson before they sold. And actually we're bitchen. That started it all.
The Dumble, Kelley, Trainwreck stuff didn't have the traction of early Mesa.
And I remember I brought my first Mesa back the same week saying it was broken. Guy plays it. Nope that's what they sound like.
Ugh
I stay with my modded Marshalls.
The only think that temporarily got me away from them were the GK 250.
But we're it started turning was Rivera.
All the Soldani, Bogner, VHT stuff came after.
And really no one cared anywhere about gear as folks do now.
I hold guitar journalism and then the Internet responsible.
