Grover Pro Woodblock with BlocKnock 10 in.

The Grover Pro BlocKnock was created for percussionists who are called on to play a multitude of instruments without consideration for stick changes. Playable with a hand or mallet, the BlocKnock is also perfectly suited to show players (whose pit work requires musical multitasking) and hand drummers too!

Each BlocKnock quickly and easily fits onto any Grover Pro wood block, and it can be removed for situations where it is not needed. Made from coated spring steel and hardwood, its features include an adjustable striking face with three positions to assure optimal sound production from any size Grover Pro wood block. The BlocKnock is available either as a retrofit accessory or as a kit with a Grover Pro wood block.
