Donner Lax Comp
Donner · pedal
The Donner Lax Comp is an optical compressor pedal from the Chinese budget effects manufacturer Donner, inspired by the smooth, transparent compression of vintage optical compressor designs such as the Teletronix LA-2A. Optical compressors use a light-dependent resistor for gentle, program-dependent compression with smooth attack and release behavior. The Lax Comp provides LA-style optical compression at budget pricing.
