I agree with all you guys said. I most likely got this from a few previous gigs where the congas were not sufficiently placed in the mix. It's sometimes hard to convince sound men and other musicians that you're needed in the mix. they think you suffer from "me me me" syndrome...this conception that percussionists are so enamored by their own percussion sounds, that they're incapable of understanding that they're too loud...etc....so they're ignored. As of this last year, I've started to become a lot more adamant with sound men, even refusing, one time, to play unless the sound was raised on the monitors.
I don't think my technique is the problem, but by all means, you guys can tell from this video -
http://www.youtube.com/watch?v=WwymCjEoedAAs to what I'm doing to solve it:
1) the callous seems reduced...I took a file and reduced it a little.
2) I laid off my standard conga routine for 4 days...seems like the joint is better now. It needed some rest time.
3) no more playing without Nexcare Waterproof tape on the joints of the index, middle, and ring fingers (the main fingers of impact for open and slap tones). I bought some over the weekend and it's going into my conga bag immediately.
4) More demand of better sound at places with sound...and I'm going to start lugging around my Behringer powered speaker and mixer combo with at least one mike and one mike stand. If I got to make my own sound, so be it.
I'm more interested in advice for non-expensive creams that can be used to prevent the buildup of such callous. I've heard divergent theories regarding Urea in Urine, or Urea in creams...or Shea Butter, etc...can someone give me a definitive breakdown on what creams should be used...how regularly, etc.
