Hmm, Boosting or lowering the lows are bit matter of taste. You may try lower lows and boost up mids between around 1k to 2k. Its hard to say, cuz its pretty much matter of taste and style what you play.
Use compressor and try lighter gauges of strings. I dont recommend using distortion, a fair amount of overdrive could be cool... but Im more for the pretty clean sound when it comes to funk. Also using compressor is a bit matter of taste, without it you may get more sensible touch to make it more groovy, but compressor makes it little easier and stiffier.
