God Speed, try adding a second battery in series to run at 18v. Gives your more headroom, better transients. I did this with my Z5 and it rocks really well in the contemporary/alt rock worship style at my church. A LOT less expensive than a new pre and new pickups! It works for some people, others still go for the more expensive options, but it's worth a try as a first effort!

I am not really having any clipping issues with the stock pre, just a lack of overall frequency. The notion of headroom is still a little confusing to me. Am I right to assume that 18v systems are just a fix for people experiencing distortion/clipping in their signal?
As mentioned before I have to boost the bass completely to get an acceptable amount of bass in either rock or gospel settings. There is no way around it. Since I have to boost the bass it can get "boomy" at certain times. Its not a distorted boom as much as it is a drone. I am thinking that having to boost the bass so much is the cause of this.
In addition the highs in a rock setting are too "bright". When playing Gospel/Funk it is actually welcomed but in a rock setting they sound a little out of place. Do you still think setting up the stock pre with an 18v setup will address these issues?
My biggest gripe with the stock electronics was the lack of bass in the signal. I would always find myself boosting the bass too much just to get an acceptable sound. Additionally, it would eat a 9V battery in about 1.5 months.
With the new electronics, the bass sounds fantastic without any boosts or cuts. This is now my utility bass that I use for rock, funk (both slap and fingerstyle), country, worship, and some new-age jazz. Plus, I have two mid frequencies to choose from for boosting and cutting and the ability to go passive for a more vintage sound.
I totally understand the lack of bass with the stock pre. I am wondering if it is in fact the pre, or if it is the pups that cause this. It could be both, but no one has swapped just a pre in that I know of. Your set up sounds perfect TBH. Are you running a 18v or a 9v system now?
