Having just aquired a killer Smith BT6G, and not played a 6 for a LONG time (Warwick Thumb 6), I'm noticing that my left forearm gets "tired" pretty quick. Like 1 or 2 tunes pretty quick. I played a 5 almost all the time for the last 10 years or so and never had any issues. I'm 1 week into this bass and wondering if this is gonna dissappear. I wasn't looking for a Smith 6 (a Smith 5 yes), but came on to a good price for it. So I thought I'd give it a spin. I wear it kinda high BTW. If you were sitting with the bass strapped on, there would be about 1 inch between the bottom of the bass and the top of my thigh. I tried lowering it and even raising it, but settled back to this height because it felt the most comfy. Any insight???
