That is almost always good advice, but....effects in a jazz ensemble?
I use some overdrive now and then when I play at my church and there isn't a guitar player....
when I was in my school jazz band we had to walk uphill both ways in cut time, and there were no effects, you young whipper-snapper......
All kidding aside, when it comes down to it - it is your art and your sound should be your own.
Having played in everything from 3 piece jazz cocktail trios to full 25+piece swing bands, though, I have to agree w/ ad that the bass needs to come through clear at the foundation, not adding mud to the mix. I have only ever found compression to add sustain when playing a lead melody to be useful. I have also found that the range of tone possible on the Bongo is a lot of fun to mess with.
Have fun with it, whatever you do!
