I am looking at buying a SOLID SPRUCE TOP U-BASS Fretted.. I noticed on the Kala web site the one I am looking at has the number 2 in the name.. Like this SOLID SPRUCE TOP U-BASS-2 Fretted My question is.. Does the 2 mean it is a newer model? And there use to be a SOLID SPRUCE TOP U-BASS-1 Fretted? Or just a SOLID SPRUCE TOP U-BASS Fretted The one I am thinking about buying is New but they just call it a U-BASS SOLID SPRUCE TOP(No 2 or nothing in the name) Thanks!
