Hi guys I have been listening back to FNM's "King for a Day..." album and just got stuck on the title track. IMO, the best song on this CD. If I'm not mistaken, Billy Gould is using a fretless bass. Do you guys know how he got this sound? Very punchy stuff. I'm looking at a new amp (RH450) but also a fretless bass. Do you think a Fender Jazz can get this type of sound? Thanks for the input.
