Minimal Series Tuner w/BJF Buffer

The One Control Minimal Series Tuner MKII with BJF Buffer is an ultra-compact chromatic tuner featuring a high-quality buffer circuit designed by Björn Juhl (BJF), housed in one of the smallest tuner enclosures available at just 94mm × 44mm × 47mm. It combines ±0.5 cent tuning accuracy with BJF's renowned buffer design for pristine signal integrity. When the tuner is bypassed, the BJF buffer remains active with 500KΩ input impedance and 60Ω or less output impedance, preserving your guitar's tone while driving long cable runs or buffering pedal chains. The tuner itself offers reference pitch adjustment from A4 = 436 to 445Hz in 1Hz steps, measurement range from E0 (20.60Hz) to C8 (4186Hz), and 12 equal temperament tuning. Drawing only 40mA from a standard center-negative 9V DC supply, the Minimal Series Tuner weighs just 234 grams and takes minimal pedalboard real estate while delivering professional-grade tuning and tone preservation.
