I've had this cool Kala U-Bass for a few years. (I did a video on it back when I got it.) I've used it on a few things, especially when I want a sort of Latin-flavored Ampeg Baby Bass sound. (That solidbody upright from the 1960s is largely forgotten, except in Latin dance bands, where it's considered the classic bass.)
But I've recently started rehearsing with a new band featuring my pals Jane Wiedlin, Pietro Straccia, and Dawn Richardson. And for perversity's sake, I decided to try using this little uke bass as the sole bass in band. (And Dawn hits those drums pretty hard!)
The above video demos some sounds I concocted using Fractal's AX8, the "light" pedalboard version of Axe-FX II, the company's flagship amp/effect modeler. I'm quite encouraged by the results! AX8 has no power amp, so I've been plugging into one or both of the Fishman LoudBoxes I use for my solo looping gigs. And if we play somewhere with good monitoring, I can just bring the uke bass and a small shoulder bag. Total lazy old guy gig!
The sonic missions were pretty simple: Amp up the lows. Nix as much of the ugly piezo pickup quack as possible. Concoct enough patches to make a nice, interesting palette for a set. There's still more to do, especially in terms of modifying my technique for the instrument. I'm still not quite comfy to the super-short scale. Also, I'm too accustomed to resting my picking hand on the body or bridge, and the piezo loves to amplify those thumping and scraping sounds.
But overall, I'm encouraged. Plus it's just sick fun. :)
