The Moollon Tremolo focuses on the natural tremolo sound of vintage tube amplifiers. The Bias circuit on Moollon Tremolo is quite different from those existing Opto-coupler circuits which make an unnatural discorded frequency range between the guitar and tremolo signals.
Depth, Slope, and Speed controls bring ease of use and wide range effect. In particular, the Slope control lets you mix hard and soft slopes gradually, not just switch between them.
The Moollon GW 109S Buffer Circuit minimizes the ground noise, electrostatic noise, and mechanical noise(popping) from the switch by transforming the input signal into a low impedance signal.
