Their numbering system is getting more and more confusing. It was easy enough at the start, the 10 series was base level with Bartolini BH2s, the 15 series was prettier and with Nordstrands, the discontinued 1265 was in the middle with pretty woods and Bartolini BH2s. MS stood for multiscale, S for short-scale, SMS for short multiscale. Now there's the EHB5MSBSP - 5 strings, multiscale, Fishman pickups, painted, so where does it fit and what does BSP stand for? The 1135MS has a prettier finish and Bartolini pickups, so maybe that replaces the 1265, in between the 10s and 15s. And the 1675MS is presumably now the flagship instrument with the pretty body and Fishman pickups.
