Kingsley Bard - Tube Tremolo





The Bard’s bias modulating tube circuit provides classic, warm sine wave tremolo tones.

The single Tungsol 12ax7 runs at high voltage for a full, rich and dynamic tube sound. The 9VDC power supply (provided) is converted to both 6.3VDC for the tube heaters and 275VDC for the tube plates.


With controls for volume, speed and depth it is very simple to set up great sounding tremolo. The volume control is a nice feature that ensures your sound does not get buried when the tremolo effect is activated. It can also provide a cut or very healthy boost.

Dimensions: 3 7/8” wide x 4 ¾” deep

Power requirements: 9VDC @ 500mA

Price: $275
