Hi Bass players. I'm Bob O'Brien a 61 year old jazz upright bass player who has been playing on and off for about 50 years. I play a German flatback bass of unknown origin made in the 1850's with a Revolution Solo pickup and use a Gallien-Kruger amplifier for small gigs. I studied at Berklee in the late 1970's, stopped gigging after getting married to pursue a day job, and retired in August (finally!!) and am playing the bass regularly again. I've kept my chops up fairly well over the years but completely lost touch with equipment, technology, trends, etc that affect bass players. I really appreciate the wealth of bass knowledge on these pages and look forward to learning from everyone here on the boards.
