As a conga player/percussionist,there is nothing more annoying than a drummer playing congas. . . . like a drummer would. First off if you do not take the time to learn proper technique you are robbing yourself the opportunity for the best possible sounds. Secondly you are raising the potential for injury. Thirdly its disrespectful to the art and history of the instrument. FYI
A nice set of LP's or Toca drums Quinto and Conga [Small/Medium] size. The largest one is the Tumba. . . Not needed but great for a 3rd pitch.
Burger Sulsbruk had a great video for beginners to advanced. Richie Gajate as well as the afore mentioned above. Get good drums [used] so when your technique improves your can really appreciate the difference. Otherwise you will be selling them down the road for "real" ones. Lp aspires may be inexpensive but. . . they sound it.
Good luck have fun PRACTICE carefully,slowly and correctly. . .You are basically slamming your hands onto a wooden edge over and over. . . [COLOR="Blue"][SIZE="1"]BOOM[/SIZE][/COLOR]
