Acoustic Percussion TB-SB – Single Brass Triangle Beater Set
Safe and secure checkout
The Acoustic Percussion TB-SB Single Brass Triangle Beater Set gives you one of each size of their brass bullet-head triangle beaters, neatly supplied in a compact carry case. Brass heads, balanced steel shafts and rubber grips provide a bright, clear triangle sound with a slightly warmer edge than steel – ideal for orchestral, wind band, theatre and studio work.
For years, Chalklin triangle beaters were the go-to choice for many orchestral percussionists. Now that they’re no longer in production, Acoustic Percussion have stepped in with a range that offers the same level of quality, consistency and bright, singing tone – making these an ideal choice if you’re missing your old Chalklin beaters.
Key Features
-
Single 4-beater set – 1 beater of each head size: 5, 6, 8 and 10 mm
-
Bright but slightly warmer tone – brass bullet-style heads keep the sound clear and projecting with a rounder edge than steel
-
Balanced feel across all sizes – steel handles give a consistent response for both rolls and single strokes
-
Comfortable rubber grip – secure, low-noise handling that helps reduce hand fatigue
-
Compact, gig-ready case – all four beaters stored together in a small, easy-to-pack pouch
Why Choose the Acoustic Percussion TB-SB Single Brass Set?
If you don’t always need matched pairs, a single set can be a very practical option. The TB-SB brass set gives you:
-
All the main sizes in one pack
One each of 5, 6, 8 and 10 mm covers most triangle writing – from soft chamber textures to fuller orchestral moments. -
A warmer take on the classic bright triangle sound
Brass heads still give plenty of brightness and clarity but with a slightly rounder, less edgy attack than stainless steel, which can help the triangle blend more easily in certain repertoire. -
A tidy, portable setup
The included case keeps all four beaters in one place, so you can quickly grab the size you need without digging through your stick bag. -
A modern alternative to discontinued Chalklin brass beaters
If you were a Chalklin user, this single brass set offers a familiar feel and tonal profile, backed up by current production and consistent build quality.
The TB-SB single brass set is a great solution for students building a serious triangle setup, teachers wanting a compact kit for teaching rooms, and professionals who prefer the slightly warmer response of brass heads.
