DigiTech BRIAN MAY RED SPECIAL PEDAL Owner's Manual page 4

For more than 30 years, Brian's signal path has begun with the Red Special
guitar and its multitude of pickup selections and phase options.
The guitar signal is run almost exclusively through a treble booster and
then directly into his customized Vox
harmony guitar parts heard on numerous Queen recordings, Brian also
used the infamous "Deacy," a hand-built battery operated amp designed
by Queen Bassist John Deacon.
For effects, Brian has relied on a Foxx
shifters, and more recently, chorusing effects using a single "dry" amp and
two "wet" amps to create his huge live sound. Some post processing
techniques used in the studio included tape flanging, reverb, and an assort-
ment of mics and amp mic'ing techniques that capture Brian's unique and
instantly recognizable sound.
