I have a 2005 Q5 that I love and I will never get rid of. It has Barts, a highly figured Walnut top and Aguilar OBP-3 electronics. I can get all kinds of sounds out of it (even old school when combined with my hands). It is also pretty heavy. This thing sounds huge when using the onboard EQ or a little jazzy if you take it the other way. A lot of people don't like the sustain they get (it can go on for ever). I have recorded with it (folk rock believe it or not) and the results were great. The recording engineer did not like the upper mids or the highs but that is one of the things I love about it. The thing I love about this bass the most is how the neck doesn't care about the weather. I play outside gigs in the summer where it is 95+ and 80%+ humidity and no problem. I have also played a show outside in the wind where it was 43 degrees outside before windchill and the neck was a champ again. My guitar player was having a nightmare and I was just trying to keep my hands warm. All that said, it is not the perfect bass for everyone. They cost waaaaay too much now (got mine before the increase), they take way to long to get if you order one. Most of the Q5's I have played in stores I have not liked so much. I ordered mine and had it drop shipped and it was exactly like one that I played in Chicago so I feel I was lucky. Lastly, it is not the only bass I take on a gig (I always roll with at least two). Depending on the gig I may use a Roscoe LG 3005 or a Fender Precision or a Lakland Skyline DJ4. I just take whatever is appropriate unless the weather is extreme and then I always take the Q5.
