Electro Harmonix Bassballs Mods

[thelimey]

Does anyone know a person who does mods on an Electro Harmonix Bassballs (US version)?
When I use mine I have to run it with an EQ pedal as well or it sounds thin and kills the tone and would like to set it up so it sounds full by itself.

You may have done this already, but try tweaking the trimpots on the inside. Those may thicken up your sound a little. Mine sounds a little beefier after doing it.

Thx for the advice. How would you go about doing that?

Don't ask me what it's all about,...it is very mojorific though. I had a link to schematics bookmarked on my old computer which is sadly kaput.

My BassBalls USA should be arriving today, and I'm planning on doing this mod myself. Will post some pics and advice when I get the chance.

If you open the pedal up and look on the circuit board, there should be two trimpots right next to each other. I don't know the exact parameter that they tweak, but I know that each is related to one of the filters in the Bassballs circuit.

I just played through mine while tweaking those trimmers until I liked the sound better. I plan to (at some point) move the trimpots to the outside and make mine somewhere in between stock and the picture of awesomeness seen above.

Am I missing something here - can you not just drill holes in the top of the case to access the trim controls with a screwdriver - or is that too redneck?

Looks like the cockpit of a 747!

I wonder what it would sound like if 2 twin filters from two units were put together? Or do you think this would just sound like two bassballs units strung together?

Trimpots are at 800 hz and 200 hz. I liked what happened to the sound when I rotated the 200 hz one counter-clockwise; the voicing got lower in the money-note area, and some classic funk riffs sounded wicked cool. My unit's a US-made nano, and now sits on "the funk board," a Boss BCB-3 that holds an NS-2 and SYB-3. Power comes from the BCB-30's TU-3, and the coupler cable.
