Hi ! I was looking for a SWR Workingman to replace my Trace Elliot GP7SM combo, and I could have a good deal on a little used Workingman 15. I would pay it cheaper than a new workingman 10... I understand is it not as fun to carry around but, is the sound as good as the sound its two little brothers for the upright ? I play my upright with bass max and fishman preamp, and i sometimes take my fender p. I play in jazz trios (sometimes adding a drummer), a swing big band, and other stuff.
