Funny coincidence. I was reading another foŕum thread about 4 vs 5 string basses. And I suddenly remembered how hearing Alain Caron's walking bass on Spider is what got me thinking: "I need that low B!!!" for the 1st time. Unable to afford a new bass, I went to MF Lutherie, bought a 5 string set and asked them to file the nut on my 4 string Ibanez to string it BEAD. A few years later I finally bought a 5er. Thanks Alain!
