...Not much, but there were positives. I played a Sukop 6 string. Amazing bass, just great. The neck was super flat (which I happen to love) and the action was the lowest ive ever seen (coyuld barely see any space inbetween string and top of fret) and thee was ABSOLUTLY NO BUZZ. Had a great sound to it, sadly, It's no unique sound. Ive gotten similar sound out of other basses. But when I started to play hard it gave a really nice, Thumb-esque growl... but at $6400, a bit too much, id only pay about $3200 tops for this percticular bass. It didnt even have fancy knobs, just plain rubber ones, doesnt look good on such a fine peice of wood. Then I picked up a Zon Sonus 5 fretted with a spalted maple top. I put it down less than 3 minutes later. I hated the neck on it. I didnt get any good sounds out of it and I was playing through a Aggie AG500 and Aggie 2x10 and 4x10!!! I was highly disapointed. This perticular Sonus sounded very thin and the low B wasnt clear and it was very loose. I expected alot more out of this, this may have just been this one bass. But this was definietely a bad first impression. Then I picked up a Jaco Sig... I flipped on the fuzz channel on the Aggie and went on playing for like 15 minutes . The flatwounds were real low on tension and the action was just right. Just a great passive fretless. Although I wouldn't dish out $2200 for it. Im much rather go Valenti or Warmoth. I really wish though, that the guys who work in Rudy's , didn'yt act like you are still playing a Squire and are running through a sh*t combo amp... . Otherwiase, this round at Rudy's. was mostly positive. Compared to the 3 other times I went and left uncomforatble and mad.
