I believe they are the same as "Locobox". Excellent info here on all the interconnected brands:

I have the "BIAS" branded distortion which is itself a version of the MXR Distortion in a slimmer case, same circuit as the Guyatone Zoom Distortion and identical to the Memphis and Coron Distortion 10 (and 15).
I have a fair number of the Guyatones of that eras, some excellent pedals.
