Loving my Rumbler!
Mine is the model with the Fishman preamp/pickup. Plays great, unbelievable sound. I'm recovering from an injury where I can't lift more than 10 lbs for a couple months at least and this bass is saving my sanity, helping me work on a lighter touch (been an electric and upright player for years) and letting me gig in the near future without endangering my health. Health issues aside, it's still a wildly cool instrument that is constantly surprising me with it's playability and sound. I've just tried the roundwound strings (that Kala sells) and am loving the bass even more. The heightened string tension and definition help make it feel familiar to me while still keeping its unique identity. Hard for m to say enough about this bass!
