I've got a Bongo 4HH and it's the only bass I've ever had that doesn't sound jangley with RW strings. Even my 5HH was outside my tolerance for jangles when I got it. Put on flats taco prontito. Anyway, what if I need a spare string or strings? What are the original strings on a 4HH? They are getting fret marks already, so I think they are nickel. I assume they are some sort of Slinky's, but which ones?
