Hey folks, Up for sale is an Alvarez RB-30 SC- NAT acoustic bass. This bass has been converted to lined-fretless. It was a very carefully done job and looks "factory". Bass is very clean except for one unfortunate finish problem on the bass side lower bout. It is purely cosmetic and does not affect the stability or sound at all. Currently strung with flatwounds. Solid spruce top, laminate mahogany back and sides. Includes a pickup/preamp with built-in tuner. Asking $275 plus shipping, including nice brown Tolex hardshell case (worth $150 on its own if you buy it new!). Alvarez didn't produce a fretless version of this bass, so this is a great way to get a fretless acoustic!
