Rubber Bass is sampled from a funny little Kala ukulele bass. It’s about the size of a kid’s guitar and has big fat rubber strings which are a nightmare to tune. It’s not very loud acoustically but when DI’d, it has a wonderful round, rubbery bottom end with a lovely hint of twang which belies its tiny stature. Its a little bit double bassy, but essentially has a character all of its own. It’s not likely to be your go-to-bass sound , but for certain things it is bloody marvelous!
