This is, I have a Sterling fretless with piezo. I'm really satisfied with this bass (it's my main bass), but really i'ts a bit harsh, most when I put more treble in the EQ. Recently I get a Seymour Duncan MM Alnico SMB4A, and a read here that someone likes more this pickup than the original (ceramic). I have too a Stingray fretted (4), and I like very much the tone it have. So, thinking that this bass it's fretless, do you will replace the original by this SD Alnico pup? And, I also read nice things about the Nordstrand MM pup, it makes sense buy one of this and replace it? Thanks in advance.
