In Los Angeles last week.
Vox AC 30 ( old model... probably studio rental) 1958 Fender Deluxe run in tandem ( both on all the time). FOH mixer blends as appropriate
Pedal board... a couple boss tuners ( signal spliters?) A boss delay of some sort... and what piqued my interest OD/Boost = Crowther Hot Cake. My ears heard a lot of Vox EL84 OD/Chime.
but then, bam, next song... no more vox tone. So I waited around and asked Neils guitar tech what was up... ( thanks mate!) so he gave me the scoop.
