I bought a new combo for my home last week and was wondering what the effects are of turning it on and off all the time. Usually I go to our practice spot, turn on our old beat up rig, practice a few hours then it`s all off. Well now I`m home a lot practicing and I like to play in little 15-30 min intervals all day long. Should I leave the combo on all day or turn it on and off or does`t it matter ? It`s a new GK MB210 and my first new amp or should I say new anything and I don`t want to ruin it prematurely. What do ya think ??
