When Yes go out on tour, Stuart Sawney from Buckinghamshire, UK, has the daunting task of maintaining and servicing Rick Wakemans massive array of keyboards, organs and synths. Stuart is credited with engineering, drum programming and guitar playing duties on many of Rick´s albums. On tour with Yes, besides midi managing modern digital keyboards, Stuart also looks after the analogue organs and vintage synths, which need to be continuously retuned, for that he uses a Peterson VS-1 Virtual Strobe Tuner and an AutoStrobe 490. Stuarts clients also include Ray Davies of the Kinks and Al Stewart.
