when you play acustic, if you play up on the neck, it gives it this really nice full "tube" like sound. obviously the neck pickup is there on the electric for that reason but its not as good. im talking about physically up on the neck of the acustic like below the 12th fret maybe around 15. is there maybe a pedal or a setting to make a stronger tube sound closer to the acustic? would a tube screamer help with this? SRV had that and he sounded pretty tube like. but is there a way to do it without the tube screamer as well? i tried playing on the neck of my electric but it wasnt as good as the acustic.
Neck pickup + strum over the 12th fret is as close as you're gonna get to that tone.

The usual term is "bell-like", I think.
