found what i was looking for if anyone else is interested.
would be very professional looking having your cab boot up in sequence.
its called a power sequencer.
guess being a guitarist finally paid off

Power-up in three delayed outlet groups
Power-down reverses sequence
Triple-mode varistor spike and surge suppression
RFI filtering with multi-stage pi filter
Power Status LED's indicate which outlets have power
Mains Wiring indicators monitor wiring integrity, show Normal and five kinds of faults
Rated 15 amps
Remote option allows turn-on and turn-off at a distance simply by connecting either a momentary or maintained-contact switch (and LED if desired)
Multiple units may be daisy-chained using PS-REL relay
Three unswitched outlets (one front, two rear)
Circuit breaker
think i might buy one of these for my rig as well
