Personally I'm not a big fan of active pickups. That said, you have to realize that what you have is simply an on-board preamp. The amp you choose will have more to do with your budget and playing style. I will always recommend all tube amps. They tend to be a bit more expensive but that tone is just not reproducible. You can get close but you won't have "THAT" tone.

If you can afford it I always recommend the H&K triamp. The head will set you back $3000. Likely the most versatile all tube amp on the market today.
