GETTING STARTED-
Before plugging in your EHX MIG-50 Amp make sure of the following:
1. Both the POWER and STANDBY toggle switches are off; set to their DOWN
position.
2. The AC voltage switch on the rear panel is set to the correct voltage setting
for your region or the AC voltage powering your amp.
3. Your MIG-50 amp should be hooked up to a speaker cabinet with the correct
impedance (a four ohm cabinet to the four ohm jack, etc.). WARNING:
Running your amp to a speaker cabinet that doesn’t have matching
impedance or with no cabinet at all could severely damage the MIG-50 and
void your warranty. Be sure to select a cabinet that can handle the full rated
power rating for your amp.
To power up your EHX MIG-50 Amp:
1. Turn on the POWER switch. Wait thirty seconds for the tubes to warm up.
2. Flip the STANDBY switch to the “on” position. It’s best to keep the volume
low when turning your amp on and then adjust it to the level you need.
3. OK! ROCK & ROLL!
