I just had my 4 string bass redone from Eb standard to BEAD, and.... I get a very hollowed, clanky sound. I bought the bass used, and when I asked about the strings I was told they're D'addarios, but the seller wasn't sure if they're stainless steels or nickel wound. Because I liked the growl from that bass I wanted to know where it comes from, and the internets told me that steel strings are part of the equation, so I assumed that's what they were. I gave my bass to a luthier to retune to BEAD, needed in a band I just joined, and gave him a set of D'addarios Prosteels, and when I plugged it into my setup I got this really hollow sound, regardless of EQ. There is also fret buzz, which I don't mind and it was there before too (low action), but now it sounds really bright and harsh. Also, while low notes sit fairly well in the mix, the higher ones just disappear. Is it just a matter of exchanging these for a set of nickel wounds? Gear in question: Ibanez SR600 with Dimarzio Model P only, GK RB400 (early one) with boosted mids and set somewhat grindy, although boosting bass or reducing drive didn't give much result; at home I use direct out from amp into an interface, and then TwoNotes WOS plugin with Ampeg fridge emulation as my 'cab'.
