Backun Musical Services Ltd. (BMS) is a Canadian manufacturer of clarinets in bass, B♭ and A and accessories, based in Burnaby, British Columbia.

After the end of the engagement with Conn-Selmer, Backun launched his first custom clarinets at the 2011 NAMM Show; these instruments were of exceptional high quality for professional clarinetists.

As of November 2019, an estimated 50 production employees produce a considerably higher number of instruments and accessories per month, with the brand's global impact being felt throughout the band and orchestra community.

Student model Alpha in B♭ made of synthetic ABS material with 17 keys and 6 rings plus optional Eb lever, with nickel- or silver-plated mechanism[15] 2.

Student model Beta in B♭ made of grenadilla (Dalbergia melanoxylon) wood, with 17 keys and 6 rings plus optional Eb lever, with nickel- or silver-plated mechanism 3.

Two custom models Lumière and MoBa in B♭ and A, optionally made of Grenadilla or Cocobolo, with 18 keys, 6 rings plus Eb-lever, with silver- or gold-plated mechanism.

Both the Lumière and MoBa models in Cocobolo are offered at a considerable extra cost as Super Series sets, in such a way that the clarinets are made entirely from the same single five foot piece of wood, and therefore has the same grain structure throughout from the B♭ down through the A.

These clarinets have a patented carbon fibre outer shell on the upper and lower joints bonded to a wood core of either Grenadilla or Cocobolo.
