{Every bass has a story...}
About a month before my fiftieth, I was scrolling reverb looking for Pbass pickups. Knowing Aguilar makes pups, I searched Aguilar Pickups, and this popped up on top. Showed it to my wife and got a disinterested shrug, not exactly uncharacteristic, but just enough for a (dim) lightbulb to go off. She had already seen it, and was planning on getting it for my birthday. A few days later, she told me about it because the listing had ended, and she missed it. Didn't show as sold, so I messaged the seller. Turns out, it was Dave Avenius, of Aguilar. I've spoken to Dave on a few occasions (same industry), so reached out directly, and it was still available. Hot Damn!
Long story longer, Dave put them in when they were testing the then-new Aggy pups/preamp, not quite 'factory installed', but close!
It's #530, Korina body, Maple Top, Wenge neck, Ebony board. Has "Built for Dave Avenius" on the back of the headstock.
It's pretty special, and my wife is forever without reproach!
