Phase 4 MT

  • Description
  • Comments


We have been getting a lot of requests lately to explore the world of microtonal guitars. This forthcoming Eastwood Custom Shop Phase 4 MT will be our first ever! A crop of new artists have started to experiment with microtonal music, so we thought this is the right time to launch a microtonal model ourselves.

We've based this on our popular Hi-Flyer Phase IV model and these are photographs of the actual prototype.

If you have any doubts that microtonal guitars rock, then check this live YouTube performance by King Gizzard and the Lizard Wizard, playing their song 'Sleep Drifter' - all of their three guitarists are playing microtonal guitars.
