How to Disable Headphones-Speaker Mute of a Guitar Amp?
See, we have a nice digital guitar combo amp with a headphones/record out jack. We'd like to connect the amp to the PA system. The thing is, it automatically kills the speaker once you insert something on it like a headphones. We swish to use the jack as a direct line out without killing the speaker.
In addition to this, I also wish to do the same thing on our electric piano with built-in speakers. It does the same thing of muting every time you plug it to the PA.
1. How do you tweak and bypass this mute function on some combo amps/instruments?
2. Does the same principle/switching applies to these situations?
Hope to see your post soon! Thanks!
