The Guild S-25 was a short-lived solid body electric guitar first listed in the September 1981 Guild price list at just $495. In some ways it could be considered a simpler version of the Guild S-250 with slightly less circuitry and ornamentation - but functionally it was still a highly effective, and well-built guitar: the same set neck, dual XR-7 pickup and two octave 24 fret neck. It had very simple controls: just a master tone and volume and a pickup selector switch - making for a very playable guitar!
The Guild S-25 was styled somewhere between an SG and a Stratocaster, but with construction, body woods and hardware closer to the Gibson - though at a significantly lower price point. In April 1981 just two SG models were offered from Gibson, the SG Standard at $769, and the Firebrand-series The SG (Deluxe) at $579. Early publicity photographs show the S-25 with simpler headstock inlays than in the image below (i.e. no Chesterfield inlay, just the Guild logo), and both headstock configurations seem to have been available, with the simpler version seen on earlier (1981) examples.
The Guild XR-7 pickups were designed to be switchable, "from humbucking power and distortion to single coil bite and clarity". This requires the optional coil tap switch, whilst the phase switch sets the two pickups are out of phase with each other. "Many players have told us also that they prefer the XR-7 without these options, for a more straight ahead, basic rock sound. The choice is yours".
