I have a fretless 82 ibanez blazer bass. Im getting a little bit fed up with the brightness of it's tone. It's so bright and clanky, and it just dosnt sound like most other fretless basses. It has a maple fretboard, a stock p-bass type pickup, and flat wound strings. I'm not sure if those are the components attributeing to its clankyness, but if theres a way to make it less bright and maybe a little more jacoish or something without just lowering the tone knob (becuase all that does is make the note sound indistinct), it would be greatly apreciated if anyone could pass down the knowledge. thanks!
