Normally this model has an 11” rim, but we chose a 12” rim to try to get a deeper sound. The rich walnut block rim is balanced with a rolled brass tone ring, making a complex but lively sound. The goat skin head also adds to the funkiness of the sound, in my opinion. It is strung with baritone ukulele strings and tuned DGBE. The customer added a scoop at the end of the fretboard for easy strumming and a K&K pickup for easy amplification. The Oregon walnut is urban salvage from the Willamette Valley and the pistachio is from California orchards.
