I think of things like this…there are pluses and minus in life, and you should stay heavily on the plus side, doing more good than not. It is not ‘transactional’. If selling this gets you something you like, it is a selfish plus, so a minus in the others column, sure, but if you do other things to help others that counter it and in general are on the plus side of life, then you are good.
You can sell it for what?
Or donate it and give yourself $100 to spend on what you like.
But my view of instrument donation is they have to go somewhere where they will be used. Who is looking for an acoustic bass?
I don’t know.
I donate dozens of instruments to kids in New Orleans via my little Noise4NOLA thing, and I know they go to good use via Stafford Agee in Rebirth Brass Band who I work with on this.
Giving your bass away for it to go unused, better to sell and buy something else with your good fortune, its still your good fortune.
On the A/E front, I was in same boat as you.
Bought one with hopes and dreams of plucking on the back patio at the fire pit.
Hated how big it was, how bad it sounded in amplified (and it sounded good as far as AEs go) but never played it. And I had La Bella tapes on it! You could try putting those on but they will need nut work and I think you will be in the same spot you are in now.
My solve … the Gretsch hollow body, about as loud unplugged as the AE, much better tone and is just a dream to play plugged in with a wide tone pallet. They make a short scale version too, and you can find used on Reverb if patient. I will never buy a AE bass now that I have the Gretsch, it ticked a lot more boxes.
Hell, even the U-Bass is better in my opinion.
it’s kinda sad that there are not many good AE basses. Martin is supposed to be ‘the one’ but I don’t intend to find out for $2000, I am good.
