The Apeiron began as a fretless instrument, but I'm really starting to dig the fretted versions. Be sure to watch the audio demo video to see and hear what this instrument can do (spoiler. she does it all). Have a listen! https://youtu.be/l-YuhZZkf8A While it has similar functionality and ergonomics to the fretless versions, of course, adding frets and - in this case - a passive humbucker pickup, reels the instrument back in to the more traditional "fretted bass guitar world" while still offering a unique and inspiring player experience. Like all Apeirons, this on has a 32" scale, 20" radius and 29 positions. Like all it is ergonomic and lightweight. This one is 5.7 Lbs! Now for the options: The fretted option automatically comes with an fully adjustable metal bridge and the passive, open face design shows off the hand wound, coil-tapped pickup. The optional wood thumb rest has been added and a satin finish. As I only work with reclaimed, locally sourced and sustainable materials, this bass is made from some beautiful ambrosia maple and copper beech - both trees lived full, natural lives here in Connecticut before coming down and being milled and kiln dried - about 5 miles from my workshop! Not quite the Apeiron you're looking for? Design your own at ApeironBass.com and I'll make it for you. You'll usually get it within about 2 months. 4,5 and 6 string options available and even the most tricked out, custom 6 string is still within a budget most players can afford.
