I got finished with the work the big boss, my wife, had me do...lol

I think more or less every keyboard player I have played with here in the United States has played through a Roland solid-state amp. Sometimes in very small gigs, the keyboard player would play directly through the PA.

For bass players, it is most common to play through a Solid State amp. There are those hardy guys who are willing to lug around one of the old Ampeg 200-watt heads.

For years Roland JC 120 Jazz Chorus solid-state amp has been very popular with jazz guitar players. The 45-watt Fender 65-tube amp has also found favor with thousands of jazz guitar players.

Guitar players like Keth Richards use 100-watt Marshal tube amps with four twelve-speaker cabs.
Joe Bonamassa uses a Fender 48 Dual Pro tube amp.
John Mayer, Steve Vai, John Petrucci, and many other famous guitar players use Fractal solid state amps. So there are guitar players using both types of amps.

Solid-state PA gear is the norm worldwide. It has become so good and so powerful that a trend, at least on the local level, has been to use smaller tube amps and mic them.

It really depends on the artist and the venue. I can guarantee there will be tube amps, vintage B3 organs, and solid-state PA at the Montreux Jazz Festival in Gevena in 2023.

JJ Electronics in the Slovak Republic works night and day to produce vacuum tubes and capacitors. I buy from those guys. China has also gotten into the vacuum tube business in recent years.

There is no telling what the future will bring, but I assume vacuum tubes will be around for a good while into the future.

I have some experience in Central Europe but much of what I have said is based on what I see here in the United States.

By the way, I am not an electronics engineer and have had no formal schooling in electronics. This has always been a hobby.

There are some people who know me from the music business, and that is why I sometimes get calls from well-known bands to fix their tube amps. They all have guitar techs that talk to each other and know who to call when they are in a jam. They mistakenly think I can do anything...lol, I can not do everything, but I know people who can and will answer my call at two AM.

“Amazing! I’ll be working with Jaco Pastorius, Charlie Parker, Art Tatum, and Buddy Rich, and you’re telling me it’s not that great of a gig?
“Well…” Saint Peter, hesitated, “God’s got this girlfriend who thinks she can sing…”
