This musical tonal combination is totally adjustable with your picking attack and guitar volume pot. The amount of boost depends on the input signal level and HOT/COOL switch position. Maximum is about +10dB on lower level notes and average is about +6dB. Simble Predriver’s special circuitry uses low noise transistor with high input impedance (over 2 Mohm) so you can boost even piezo pickups without tone loss.
