Sound — 10
I would consider the Thunderbird to be a one-trick pony. It's built to rock and rock it does. You can dial in on an extremely round sound with a very crisp attack very easily with the two volume blending knobs. I usually plug strait into my Fender Rumble 100 and get a wonderful sound. Sometimes I play through a Big Muff Pi Fuzz pedal but it sounds great either way. I use it in both grunge and classic rock settings. Best feature of this bass!
Overall Impression — 9
This is definately one of my favorite basses that I own and I would definately buy it again given the choice. It is a perfect match for anyone playing rock or even metal styles and it can take an extreme beating. I would definately recomend this bass to any intermediate to advanced player.
Reliability & Durability — 6
This bass is built like a tank! It is huge. I would not recomend playing this bass Live to anyone of small stature because it will eat you alive. I use a locking strap which is necessary because of the placement of the top strap button. The neck also is very heavy and tends to divebomb to the floor. Overall the bass is very trusty. If I could only bring one bass to a gig it would be this one but I wouldn't recomend ever doing that with any bass.
Action, Fit & Finish — 8
Overall I was very pleased with the setup on this bass. I tweaked it but only surprisingly little considering it came in the mail. The action is set slightly high but it is well suited to pickstyle playing. The hardware is top notch with little or no flaws.
