Well, my new John East P-Retro is installed. Took me a little while to install, as I messed up my first pickguard because I had the (charge light) bezel too close to the preamp. Another issue I had was the shafts were a little long, and causing the knobs to be a bit high off the pickguard. I sent an email to John East, and all I can say is "Fantastic" customer service. He replied to my email within a few hours, and he gave me a great location for the bezel to be installed. He also brought to my attention that the shaft height coming through the pickguard was adjustable via the nut on the underside of the pickguard. The reason for the light bezel is because the preamp is powered by a rechargeable battery that is charged via the output jack.

The video doesn't have the greatest sound because it was recorded on my Fuji Finepix J-10. My Markbass rig's eq was set flat, and the bass is a 2008 Fender American Std. P bass.

Info from the John East website:

The P-Retro is a simple but flexible active/passivebass preamp equaliser which offers huge tonal variation to one of the most popular styles of bass of all time, without the need to permanently modify the instrument itself. P-Retro features two stacked knobs each with a pull-switch, class A FET input stage and a high quality relay for pure passive bypass. Power is provided by an internal rechargeable battery.

The normal volume control becomes the Volume/Tone Stack and works in exactly the same way as the P style bass original controls, passing the passive signal directly to the jack. When the volume control is pulled up, the active circuit is switched in, post passive tone control, and adds 2.5dB of gain with a flat response. Additionally, the upper knob allows either a mid boost, or a combined bass/treble boost. The lower knob sets the variable frequency points for either mode.
