It's much easier to read the elapsed time on the right side, which is obviously not useful.
Thing is, I would rather surf classifieds like the rest of the forums, by update.
That is a very different question from the one you asked.
'Most' amps will let let you line in via the fx return. I think it's more usual to have the onboard DI taken from before that point but even it it isn't the original question is moot anyway because you'll never know until you get there.
It seems what you are looking for is a comprehensive preamp with its own DI out and line out. If you set it up with a PA friendly sound and use the stage amp front input for monitoring you're all set.
There's many ways to skin that cat depending on whether you are using fx and how coloured your own amplification is. You might be looking at a new FRFR rig for yourself to go with the preamp.
Beware the rabbit hole.
A lot of tunes you will find the note for note bassline only properly grooves if the rhythm guitar cops it right on. Drums also. As soon as one of them wings it you can forget about note for note.
Generally it takes the guitar player to get with the programme and then the drummer will fall in.
Once upon a band jam both my feet left the ground simultaneously. There is no other way to describe it. I didn't jump, I was lifted up by the music. I can't fake that.
