Title: Bass Direct Box PCBs?
Post by: peAk on July 26, 2014, 05:24:51 PM
Finally bought a Fender Jazz Bass for recording and was curious if a DI box pcb existed anywhere?

Just increasing caps will allow more low end frequency, sometimes you need to change a resistor or two, usually the in and out cap works for http://www.muzique.com/pcb.htm the multi purpose opamp pcb will work for a transformer less direct box, otherwise it's really cheaper to just buy one. Transformers alone ate bout 80,00 when I was looking. Otherwise, I use a tonebone bassbone.

Haven't built it yet, but I have the pcb for this: http://diy.thcustom.com/shop/balanced-line-driver-v1-0-pcb/

Looks like a great design.

Works Flawlessly! And it's just a line driver, no need to bother about caps and what not it will simply convert your instrument level signal to balanced. Neato!

I paired the line driver pcb with an NE-1 preamp on vero (and a compressor, and a fuzz, lol).... works great.  That line driver is fantastic.

when I originally posted the thread, I was hoping something more along the lines of this would be out there for the DIYer:

...but these suggestions are great too.

Well, mine is close-ish I suppose.  The NE-1 isn't as anywhere near as comprehensive as the Sansamp, but it still sounds great.

There's a Bass Driver thread on Freestompboxes, someone has an etch there.

There's also the Shadowsky vero layout at Mark's site.

can it be upside-down??, i mean if i want to set the console as input(balanced line) and get an unbalanced output??, i think those are named reamping box, can it be done without a transformer??
