I have had problems with my left wrist for several years now. Actually my whole left arm. First it was tennis elbow, then rotator cuff problems and them some signs of tendinitis and carpal. This has decreased my speed a lot. From time to time I have pain and I rest it and have seen doctors about. About a year ago I switched from fat thick Warwick necks with narrower 5 string spacing (FNA Jazzman's and Streamer Jazzman's) to the Streamer Stage I Wide Necks (20mm). This helped a ton. But it wasn't until I sat down with a Metro for almost two hours that I was sold. Not once in that time did I experience ANY pain. This was is one of the reasons I switched. For the last week I have only been playing two Sadowsky's I now have. Not only am I not experiencing any pain at all BUT my technique is getting better AND I am playing with a much light left hand (fretting hand) touch. Last night after the kids and wife were asleep I loaded up a full set of country songs (about 75 minutes) and ran through them like a typical set. No problems. Actually felt great afterward. Tonight, I just did the same with some old school disco/funk and some Pink, Christina Aggie, etc... No sweat! I know I rave about these basses but this is why and I am getting therpeutic results as well. Such a perfectly formed instrument. This is exactly what I needed. Not to mention the tone.
