If I could have only one, and it could be any one, it would be Randy Jackson's Big Al 5 in powder blue. Out of my basses, I'd choose my 25th Anniversary. It hass soooo many options with all those buttons.
If I had to have only one, it would have to have supreme flexibility but also have that distinctive EBMM tone and character. With that in mind, I'd choose a Stingray HH.
I'd go with my 30th anni SR4 no doubt. It's my first ever EBMM and was an amazing eye opener after 20+ years of playing other brands, and above all: it's a wicked bass with an amazing Stingray character.
I have always wanted a Sterling HS Blue Dawn Finish with a Maple fretboard and a unpainted headstock. that would be my dream bass. 2007 SE Sterling is nice but i never been a fan of the matching headstock and i dont really dig the SE logo at the 12th fret. maybe they will bring Blue Dawn back in to production again or at least as a custom order bass.
