Thanks for posting and making these. I grew up with the MXR + but we never stacked them.
As far as feedback goes, maybe try and make them shorter.
I just started a channel too and I notice that I'm losing viewers after 2 or 3 minutes. I check all my google anylitics data.
So I'm going to try and edit mine way shorter next time.
Anyway thank you for miking your amplifier properly, tuning your guitar and not wearing shorts, sitting with your legs akimbo ha ha
