My friend has just bought a Strat Acoustasonic and loves it. Thanks to lockdown I’m yet to have a go. I have the TaylorT5Z which is similar to the Fender and predates. Has more trad controls - acoustic pickup and 2 pickups and I’ve thought several times that this would make a good bass.
I also have a Spector Spectorcore which is pretty much what we’re talking about. Semi hollow body (but not much acoustic sound) Fishman piezo in the bridge and a magnetic pickup. I like it, but I notice that it seems to have disappeared from the Spector website, which probably means they’ve stopped making it.
I’m guessing that Fender and Spector found that the market for such basses is pretty minimal. There is still the Ibanez one but that does have the magnetic pickup.
