Mutable Instruments Shruthi – DIY Build – SMR4 MkII Filter – Laser-Cut Wooden Case

Hand-built Mutable Instruments Shruthi synthesizer, featuring the classic SMR4 MkII analog filter board and a custom laser-cut wooden enclosure.

This is a DIY-built instrument, carefully assembled and housed in a unique wooden case, giving it a distinctive look compared to the original plastic enclosure.

The Shruthi is a compact yet powerful hybrid synthesizer, combining digital oscillators and sound generation with a warm, characterful analog filter. The SMR4 MkII filter is particularly appreciated for its smooth, musical response and classic analog character.

Features:

  • Mutable Instruments Shruthi DIY build
  • SMR4 MkII analog filter board
  • Custom laser-cut wooden enclosure
  • Digital oscillators with analog filtering
  • Powerful modulation and sound-shaping capabilities
  • Compact desktop synthesizer

A great little synth for electronic music production, sound design and experimental sounds.

Please note: This is a DIY-built instrument, not an original factory-assembled unit.
