Listing Detail Tabs


Frogman is an optical tremolo effect based on the tremolo mounted in the vintage tube amp. That tone will demonstrate your way at a high volume. When used in conjunction with distortion and overdrive etc. unexpected sound jumps out. This Frogman tremolo is made by optocoupler. This type of tremolo has the feature that it can not be colored naturally. Neither clean nor distortion will affect the original sound. The range that can be adjusted with DEPTH and SPEED is very wide, and it is possible to adjust from a tremolo tone of trimmer cut to a slow tremolo effect.
Frogman has a VOLUME COMPENSATE knob that can compensate for the effect sound and the original sound, respectively. You can seamlessly match the original sound regardless of whether tremolo effect is on or off.
In addition, Frogman has a SHAPE switch that switches between two different WAVEs. Square Wave is a step-like feeling like chopping. Triangular WAVE is a smoother feeling.
Frogman is an effect that can create unique and distinctive tones. It is ideal for alternative rock, art rock, blues etc.
