Ripple

Donner is a Chinese manufacturer producing affordable guitar pedals. The Ripple expands on basic tremolo with additional wave-shaping controls for more varied modulation effects.

Beyond standard Speed and Depth, the Ripple likely includes wave shape selection or bias controls that change the tremolo character from smooth sine-wave pulse to more aggressive square-wave chop.

Mini-pedal format keeps it compact while true bypass ensures clean signal when bypassed. For players wanting tremolo with more tonal options than basic designs, the Ripple offers expanded modulation at budget-friendly pricing.
