There are quite a few guides in the OM Tech Talk Section. We carried a basic one over from the old forum covering Zoom set up HERE but @jkahn did an updated guide a couple of years ago HERE .
Maybe worth having a look at both. Richard’s post above is also very helpful.
What you do have in Zoom is the ability to set up a meeting with . . . . well just you !!
Once you have the audio settings are covered, you can open a meeting, hit the record button and experiment. By which I mean proximity to mic, vox guitar balance etc. So you can play back and get an idea of what the sound will be like.
Shout up here if you need any help in doing that.
And for context, when we first started out on this OM journey, we were all where you are now and tripping ourselves up on the tech side. Plenty of experience and peeps around to get you sorted !
