Two of the greatest vibes players have designed mallet lines for Malletech. These lines are made like no other vibe/marimba mallets. Their rattan handles are measured for length, diameter and flex. The cores are tested for hardness and the wraps are counted as the heads are wound. The 100% nylon tight-weave yarn resists wear and actually sounds better with use. We frequently hear from players who own sets purchased 10 or 20 years ago - and they are still making music. The finished mallets in a set are individually weighted to not vary more than seven one-hundredths of an ounce.
