I have a very old Washburn AB-20 with piezo under a bone saddle and Roto 88 tapewounds. I've been trying to get a good simulation of an upright - and I'm starting to think I may just need to get a real upright and learn to play it What I notice is that unless I fret it perfectly (unless I'm directly behind the fret) the string can rattle on the fret and the piezo pickup exaggerates this in a really annoying quacking noise. And, of course, I ought to always fret perfectly - but I'm a fairly new bassist so I don't get it perfect every time. It's tempting to defret the bass and make a fretless - but I do have a fretless jazz bass already. Here's a short clip of me recording the Washburn directly into the DAW with the mids pulled out using the EQ on the bass. Can any of you give opinions of the sound and suggestions for how you deal with piezo pickups? Thanks in advance.
