LP Classic Top Tuning Congas make on-the-fly adjustments quicker and the head tunes more evenly for good fundamental pitch. Its low profile design insures hand comfort. The 3-ply 30" Siam oak shell has a fiberglass layer added to the inside upper portion of the shell for additional strength. The conga is fitted with a natural rawhide head for authentic sound and easy-on-the-hands modified Comfort Curve II rims. The shell comes with reinforced LP Heart side plates with 5/16" diameter tuning lugs and new LP shell protectors. A tuning wrench is also included.
