Making My P Active

I've done the OBP-1 route before and really liked the results. it's a fairly simple mod:

* dual battery box on rear + wire tunnel to control cavity

* small route under pickguard for the OBP-1

* replace original Vol knob with a stacked Vol / Passive tone control

* replace original tone control with a stacked Bass / Treble control

* add an on/on micro switch to the pickguard to bypass the pre-amp if/when desired


Minimal routing work, minimal expense, minimal visual ability to see it's not a stock P-bass from a distance ... maximum flexibility from a tried and true workhorse

all the best,

If considering something as significant as routing the body, I'd make changes one at a time, i.e. reduce the number of variables. I'd make sure I found the pickups I liked first (maybe they'll even make everything alright by themselves) and then if still not happy, route the body for a preamp.

...Or it might be the case that you're already sure that both of these changes are what you need.
