I had a number of challenges in performing through Zoom for an online open mic.
There is a separate setting under Audio for musicians.
Here’s a link that tells you about the settings for various versions of Zoom.
The original video of my performance, consisting of the nights jam, is 3 hours long and doesn’t belong to me, so I am including my 15 minutes practice set instead. For the diatonic,
I use Special 20 reedplates on a recessed brass comb from Blue Moon
The chromatic is a Hohner CBH 2016.
I am using a Bulletini mic with the Xvive U2 Wireless Guitar System,
through a 1963 Premier twin 8 amp (volume:5,tone:3, tremelo:3). No effects.
Here is my 15 minute practice set.
