I do not use new gear for bass, but if nobody uses new gear, they will have no reason to make other amps than those who are inexpensive, break down and can be replaced only by new cheap gear
I must say that Peavey stuff is reliable, but I never liked it because it´s not the tone I´m after.
I owned a solid state Peavey head with Peavey 410 + 115 cabs, never got a sound out of it.
Used a TKO and a TNT as a kid, but got rid of them fast. I even liked my 60w Carlsbro 112 combo better back then.
The Carlsbro broke down after a year or so, but the Peaveys are still around and working I suppose.
Recently, though, I have had some new inexpensive Peavey tube amps (guitar) coming to my shop for repair.
I´m amazed how new some of them are, melted tubes, loose components, strange sounding.
Maybe they are becoming sloppy too? I guess you get what you pay for, but Peavey does have a history of
making good solid amps, even for the cheapest, smallest amps.
