STG 8051-3
Not a synthesizer at all — this is a three-reel mono tape box of Handel's Messiah, and one of the more curious entries to ever land in the STG catalog.
Overview
The first thing to get straight: the 8051-3 is not a piece of hardware. It is a pre-recorded tape release — the complete score of Handel's Messiah, issued by Saga Tape Records on a set of three reels, mono, at 3¾ i.p.s., carrying the catalog number STG 8051-3. Collectors who come to this page expecting a synthesizer or a signal processor will find instead a 1961 tape edition of a choral warhorse, packaged and sold as part of Saga's STG line. The "STG" prefix is the label's tape-series designation, not a manufacturer of instruments.
The performance itself is a London affair. The London Philharmonic Choir and the London Philharmonic Orchestra are conducted by Frederic Jackson, with a solo quartet of Heather Harper (soprano), Helen Watts (contralto), Duncan Robertson (tenor), and Roger Stalman (bass). Christopher Wood plays harpsichord and Ralph Downes handles organ. The complete score was advertised as a first on tape — Saga's own promotional copy in the pages of Studio Sound (November 1961, p.3) billed it as "for the first time on tape," a claim that speaks to how young the pre-recorded classical tape market still was at the turn of the 1960s.
The set was sold in mono only at 3¾ i.p.s. on three tapes for 97/6 — that is, 97 shillings and sixpence for the complete box. Saga's advertising in Studio Sound (October 1961, p.3) positioned the release alongside a "De Luxe Version" in stereo, catalog STF 4051-4, running at 7½ i.p.s. across four tapes at 12 guineas. That stereo edition carried a different catalog prefix and a different reel count, and it is a separate product — the 8051-3 is the mono three-reel set, full stop. Buyers who see the two listings conflated online should note the distinction carefully.
What makes the 8051-3 interesting to a tape collector is less the performance than the artifact: a complete Messiah spread across three 5-inch spools, packaged in what Saga described in its own advertising as "attractive full-colour pictorial boxes." That packaging language comes straight from the label's promotional pages, not from an independent assessment, so treat it as marketing rather than a verdict on the box's build. Still, for anyone assembling a representative shelf of early-1960s British pre-recorded classical tape, a complete choral work on three reels is a substantial object — the kind of thing that takes up real space and requires a deck that can track 3¾ i.p.s. mono cleanly.
The 3¾ i.p.s. speed is the crux of the ownership experience. At that speed a three-reel complete Messiah is a long listen, and the format trades tape economy for fidelity — the same trade every 3¾ i.p.s. classical release of the period made. This is not a tape to judge on a deck that has not been gone through.
Saga's own catalog pages, reproduced in the period press, show the 8051-3 sitting among a busy STG run — George Chakiris singing Gershwin (STG 7024), Grieg's Piano Concerto with Eileen Joyce (STG 7017), Tchaikovsky's Pathétique with the Bolshoi under Melik-Pashaev (STG 8003), Chris Barber and Lonnie Donegan (STG 8063), and a long list of light-orchestral and dance-band titles. The numbering is not strictly chronological or genre-sorted; the 8051-3 simply occupies its slot in a label that was pushing out a wide spread of repertoire on tape. Collectors note that Saga's tape line was prolific and its packaging consistent, which makes a complete run of STG titles a coherent — if sprawling — collecting target.
A note of caution for anyone cataloguing this release: the 8051-3 turns up in period advertisements and dealer listings rather than in formal review columns, and the surviving documentation is largely the label's own promotional material. Studio Sound's pages through late 1961 and early 1962 carried the release repeatedly as an advertisement, and the same pages carried Saga's broader tape catalog. That is useful for establishing the release, the price, the personnel, and the format — but it is advertising, and should be read as such. There is no independent measured review of the 8051-3 in the available record, so claims about its sound quality rest on the listener's own deck and ears rather than on a period testing panel.
For the collector, the practical questions are condition and completeness. A three-reel set is only whole if all three spools are present, and the pictorial box — however attractive the label's copy made it sound — is the part most likely to have suffered over six decades. Tape itself is the fragile component: 3¾ i.p.s. mono classical releases from this era are prone to the usual age-related ills, and a set that has been stored badly will show it. Buyers should expect to inspect spools and boxes rather than trust a listing photo of the lid alone.
It is, in the end, a strange thing to find in a synthesizer catalog and a perfectly sensible thing to find in a tape archive: a 1961 Saga box of the complete Messiah, three mono reels at 3¾ i.p.s., sold for 97/6, and still one of the more distinctive corners of the early British pre-recorded tape market.
