Fishman Blackstack Passive Soundhole Acoustic Guitar Pickup

BlackStack’s battery-free design incorporates ceramic magnets for a brilliant acoustic tone, greater hum cancellation and a vintage sound that can cut through any mix. The provided 5-foot cable features a premium TA4 mini-XLR connector to a 1⁄4” combination endpin jack for temporary or permanent installation. 

Individual string output can be balanced through the use of BlackStack’s adjustable pole pieces. Use the included hex wrench to adjust the pole pieces higher or lower. Adjusting the screws higher or lower will result in more or less output from the string closest to the screw.

• Humbucking magnetic coil with cutting vintage sound
• Passive design for battery-free operation
• Adjustable pole pieces allow for perfect string balance adjustment and help to compensate for varying string heights between instruments
• Included 5-foot cable featuring premium TA4 mini-XLR connector to ¼” combination endpin jack/in-line connector for easy installation and removal
• Designed to fit most steel string, flat-top guitars with a minimum 3 5⁄8 – inches (9.2cm) diameter soundhole
