For sale only: Sonic Research ST-200 Strobe Tuner Zero latency true stroboscopic display True bypass Muted output Extreme accuracy: +/- .02 cents Instant tracking Drop tuning up to 6 semitones Works perfectly. In very good condition. Some pock marks on the rubber pad as shown in 2nd photo, otherwise very light wear. Includes a 9v battery. There's a plug to receive 9v AC but no power cord is included. This offer includes the original box and manual. I am the original purchaser and have treated this unit well. I'm replacing it with the new ST-300 model only because most of my gigs are outside in bright sunshine and the ST-300 has a slightly brighter display. Price: $52.95 shipped CONUS, PayPal only. Thanks for looking!
