Oh I see we're comparing the purchase of used instruments that have been on the market long enough to establish a stable resale value to the price of a new bass model that recently came out and has only had one or two hit the market so far. Gotcha.
So you came into the thread saying Sadowskys are the best. Then bought an in stock SB5000, got it and didn't like it initially. Then came back and said it was the best bass you'd played in years, then came back and said the pickups hum and that other significantly more expensive, Japanese made basses have better setup, lower action before it buzzes, zero issues, no hum, better preamp, better pickups, etc. My guess is you'll take advantage of Carvin's 10-day return policy soon and return the bass for a full refund since it failed to pass the jzucker test?
