Moog Guitar Model E1
Moog may be best-known for creating synthesisers, but with the E1 the company's synth-wizards have used their know-how to pack a guitar with tech.
Most notably, it's capable of the most Spınal Tap thing ever – infinite sustain, on one string or several. It comes with a pedal to control Harmonic Blending and ladder filter effects for prog-tastic noises, plus optional MIDI compatibility. Tasty.
