I like Bill Nash’s basses too. Nash makes great retro-style basses. One of my favorite basses is the “Flame Thrower.” This bass was actually in a fire and, I kid you not, it practically melted in that blaze! It’s so punk! And it pretty much play’s itself. Totally thrashed! It’s one of my favorites!
