Love this bass and only want to sell to upgrade to a hybrid Karr. I commissioned this bass from Upton in 2013 (Opus 349), and it's been well played in the year and a half I've had it. It's developing a nice, robust fundamental tone, currently strung with D'Addario Zyex. It's also worn Sprio mittels to great effect. A Revolution Source pickup is installed in the leg of the bridge and sounds great - you can see/hear the bass being played amplified at this link (performance starts about 2:15): In addition to the pickup, I also had Upton install bridge adjusters, edge bumpers, and a New Harmony carbon fiber endpin. A deluxe UB cover is included. Asking $2900, (relatively) local sale highly preferred. Willing to travel a reasonable distance to meet very interested parties. Thanks for looking!
