Second rehearsal with the Super P5, and I've realised three key factors of why it/precision basses sound so good in a band.
1. It locks so well with the kick drum. It dawned on me today. Something about the low end character just fits beautifully with the kick drum.
2. Midrange character. There's something magical about the P pickup and its placement on its own. Throaty enough to push through a band in the mix, yet at the same time not harsh or in the way.
3. Full and filling low end. The low end character is just right. Smooth, full and filling in the sound where the other instruments can't go. It's the glue that binds the mix together.
I couldn't be happier with my Super P5 purchase. It's all I ever wanted and more. My band even commented on it today. They are all gear nerds (in the positive sense), and have great equipment. While my old custom bass was good and they liked it for five years, they could instantly hear and feel the difference with the Super P5. They wanted to want to like my old bass better, if that makes any sense - but the Dingwall just instantly had them excited. Our drummer commented after one song how great it sounded, and how it made him sound better as well.
I'm a happy bass player today.
