Fretless and flats as well. Not sure if DiGiorgio uses flats, but isn’t the typical recommendation for fretless basses to use flats? Regardless, flats and fretless certainly are not common in the heavy genres. I’m the only bass player I’ve ever met who uses flats, aside from my friend who decided to risk his GC gift card on flats to cop Steve Harris tones. I have this friend to thank for my love of Maiden in general, thankfully, and for my love of flats.
I can’t do rounds any more. Recently bought a “new” bass, and love how it sounds with rounds, but besides totally clean or slap, everything sounds better with flats to me. And considering I’m never totally clean or have to slap, flats will likely win out.
Yep... And you never find fretless in pop or rock or anything aside from fusion, haha. That said I love me some dead SS rounds on my fretless basses. But I also play with distortion so I'm very much not the target market, heh.
