id agree with cutting your losses if the bass didnt sound like what you expect or want acoustically. that experience i had with the 75ri really taught me alot. and prior to that, i thought i had it figured out.
the thing sounded bright and snappy acoustically, but EVERY set of pickups i put in there sounded super grindy and not like my 78. i knew from the acoustic sound that it had to be in the guts. it took buying a set of 70 jazz pickups and putting them in that bass to figure it out.
+1 It is easy to think about all the parts of an instrument as 'linearly related'. However, EVERYTHING in an instrument is non-linear, meaning that components differentially interact with one another based on the character of each component. And I'm not talking about two way interactions (you can tell I'm a statistician during the day), but three, four, and even higher way interactions that make exact predictions of tone based on spec kind of like predicting the weather.
It can make you crazy. I've solved that by only purchasing 'completed' instruments, and either returning or selling the ones that don't totally speak to me both acoustically and 'electronically' after minor tweaks. It took me a while, but now have been playing the same primary bass coming up on 4 years (and I've yet to find an amp that it doesn't sound at least decent with), and have zero GAS for anything else. However, it took a bit of cash and time to get there.
