I have a combo with high and low inputs. And I was wondering what would happen if I split my guitar signal and plugged into both ...

Anyone done this? How were the results? More overdrive?

OK, I'll let you know ...
You know, after all these years I've never done it.

What you are trying to do was very common on old Marshall amps, the ones with 4 inputs. One would go guitar into input one, from input 2 out into input 3 with a patch chord. Each of the two inputs have their own volume (kind of like a two channel amp with 2 inputs each). One channel is bright, the other dark. Mixed together they gave you that great OD tone of the sixties/seventies with more gain (Hendrix and Blackmore etc.)
Also works on 59 Bassmans

On a "regular" amp with 2 inputs for one channel, it would generally reduce power if you either plug in two instruments of split one into two. (not recommended)
What amp are you referring to?

you can preamp one channel into the next with a 2 channel amp

but generally when these say high and low they are referring to a db cut or sometimes an eq cut

some of the inputs would have a resistor on the inputs

doubt if you would like the results if you combined them.

this reminds me of when I was a kid I had (still have it) a black face prineton reverb and I would plug my guitar into input 1 the bass into input 2 and then we would wire in a mic by taking apart the jack of the mic and alligator clipping it onto the bass input.
we were poor and damn did I blow up speakers

Nothing happened. When both were plugged in the high took over. No magic. Oh well.
