They did a brown CE-2?
I thought all of the BOSS chorus pedals were a shade of light blue. I know the OC-2 was brown. But I’ve never seen a brown chorus. BOSS color codes their pedals last I heard. The only exceptions are their drive/dirt boxes which seem to have widely varying colors, although the ODs seemed to have finally settled on yellow.
Boss did a run of brown bass pedals in the late 80s early 90s
I still use the Flanger BF-2B and Parametric EQ PEQ-B3
The Para is IMO an extremely undervalued pedal
