Nice score there, Steve. I generally like flats on my basses.
Until recently only my Tobias 6 had roundwounds, but I was missing some mwah on my fretless with the flats on it, so I've just swapped in some roundwounds and they have re-awakend the tones. Don't know if I'll keep them or not. The Thomastik Enfield jazz flats on it were quite old, so it may be that I'd slowly forgotten how they sounded when new. Deciding whether I'll replace them with more TE flats or try their Jazz roundwounds.
