There's a gain switch on the back of my guitar pedal and I hear no difference when it is switched. It has the two choises of -10dBm and +4dBm. The manual is vague about it. Like i said I hear no difference and would like to know if anybody here knows exactly what the switch does?
Thanks. |

sends to the amp(I think)

Could it not be noticable by the headphone port? |

4dBm equals 2.5 watts of power
10dBm = 0.0001 watts of power
I think it's in relation to amount of power outputted. But then I'm sure you'd hear some difference =/
What exactly do the instructions say? |

Mabye the difference is NOT apparent using the headphone port. Could that be the case? |
