For sure I'll do it myself.

I love electronics...in fact I took electronics in high school then pursued it further in my adult education after high school. Yeah I checked out Spectors diagrams that they have and it looks really simple.
How do you like the East pre now that you've had it awhile?
Cheers!
Well the first thing is that the pre amp (U-Retro with an added Mid control) is SUPER LOUD. It has trim pots inside that are set to 3/4 at the moment (I havent dialed in the right volume yet, im kinda lazy) and I cant put the volume on the bass up more than about 2/3 of the way without overloading the amp on the way in.
Its mega hot.
The next thing is its versatility. I have a 4 band EQ in my bass spread on 4 stacked pots. Theres a bass boost knob at 50Hz, treble boost at 3kHz and cut at 1kHz (on the same knob, its indented in the middle to let you know when youre boosting or cutting).
Then theres two pots that have mid sweeps on the bottom, one ranging from 125Hz-1kHz and the other 250Hz-1kHz, the tops are boost and cut (with a center indent to let you know when youre boosting or cutting). The one that ranged from 125Hz-1kHz has dip switches inside to let you pick the frequency range.
The last stacked knob is the volume and pickup selector that allows me to blend in or blend out whichever pickup. Theres a middle indent to let you know when youre even on both.
I may have the exact frequencies wrong, but thats the jist of my setup. It's takes a little longer to dial in a tone what with all the knobs and choices, but I prefer having a much greater variety of tones available to me. For me, it bring my Euro 5LX to the next level and really lets me dial in the exact frequencies that make that bass speak the clearest, punchiest... whatever it is im going for.
The pre amp itself definitely adds a lot more punch to an already punchy bass.
