And here's one, with both guitar and bass, from JustNickMusic:

The new optical ones have essentially the same tone and action as the OTA originals, apart from these details: It uses a charge pump to boost the 9V supply to a higher internal voltage, to reduce the chance of clipping, for you players with high-output basses. With the new Opto models you can get a serious dip-and-swell effect at the maximum setting of the Sustain knob. Lower settings get a more natural and unobtrusive action.
Initially we released two Opto versions: "Tough" and "Suave". The suave ones soften the compressor's reaction to the initial peaks of your notes, which gives a little more transparent-sounding action and reduces any artifacts. The tough ones respond to your note attack more strongly and quickly, which gives the start of the compression more of a funky character. They are otherwise the same. Those versions are now retired, because we have a newer version that incorporates both models! It includes interior DIP switches to toggle between Tough, Suave, and two "in between" positions, for a tremendous range of versatility and fine-tuning to your taste.
The OVNIFX Smoothie compressor is packed with features such as clean blend, tilting EQ, super low noise, very wide frequency range, and an LED to indicate the amount of compression.
