Would a J-Retro preamp work in a Fender Mustang/Musicmaster? You techies out there are probably rolling on the ground laughing at this idea. And maybe it's just not either possible or beneficial. I just like the way those basses look but wish they had more tonal variation. A part 2 of the question: any short-scale basses out there that have a retro vibe but souped-up electronics? I wish Lakland would introduce one (hint hint).
