Pearl’s Surdos are the bass voice and foundation of our Brazilian Percussion Line.

Creates better tone and sustain by removing all mounting hardware from the shell.

Pearl's Symphonic Series Concert Bass drums provide a solid resounding bass tone, featuring 100% aged Maple that offers warm, well balanced tonal qualities, excellent projection and lasting resonance.

Today's music requires instruments with power, projection, and fullness of sound, Today's percussionists demand instruments that have a tonal quality that can be used in the studio for the most delicate passages, powerful enough to be heard at the back of the stadium if needed, and durable enough to last on the road. Pearl Symphonic concert toms do all that with the best hardware on the market to back it up.

Pearl's Symphonic Series Concert Toms feature a 6-ply, 7.5mm 100% Maple Shell for lush mid-tones and full sustain.

The Double-Headed Toms are equipped with Pearl’s outstanding R2 Air Tom suspension system. Its exclusive four-point floating isolation platform was developed following a two-year research and development journey. By understanding that every drum's best mounting point is in the CENTER of each shell, mounting weight is equally balanced across two floating points at the top and bottom of each tom. This gives true tonal separation from mounting hardware and enhances sonic output.

The Single-Headed Toms are equipped with Pearl’s Opti-Loc suspension tom holders allow the shell to resonate freely resulting in maximum sustain and resonance.
