to be fair i just turned the avo over to amps and it read 1amp...

Uh. That's not how you measure current. You put the multimeter inline with something to measure the amount of current it is using. If you just connect it across the PSU then you're effectively shorting it out which can be dangerous. Just look at the label to work out the maximum amount of current the PSU can supply. Use a multimeter to work out the voltage. In this case, your PSU is probably a 12V unregulated one and should be okay powering the empeg.
