Brian May
May's celebrated black plywood board ran the Red Special through a BC149 treble booster, a dual extra-booster box and a treadle-controlled phaser before the AC30s.

Fryer Guitars documents this exact black-board order from conversations with Brian May, Pete Cornish and longtime tech Brian Zellis. Cornish's separate July 1982 system archive corroborates that the two boosters still preceded the Foxx phaser in the successor rig; it is not treated as a photograph of the earlier board. Echoplex footswitches controlled offstage parallel delays and do not carry guitar audio, so they are excluded. A CE-1 appeared beside the black board at its final June 1982 show and is outside this representative 1977-1982 chain.
