Full Windows/Apple desktop/notebook and a separate inexpensive webcam and stand separate from the notebook/desktop is STRONGLY preferred.  These days with Zoom music lessons devices go in order from best to worst listed below:

Macbook/Mac (I have used both PC and Mac and I know personally that this is the best)
Windows 10 PC (Does the job well too, Macs just offer a little more bells and whistles)
iPad (latest generation, sound quality is poor do to lack of adjustments)
iPhone (last 3 generations, but you can not see screenshares of music because it is too small, sound quality is poor due to lack of adjustments)
Chromebook/Android Tablets (They do not have the adjustments to sound quality that the others do and wifi is weak in Chromebooks)
Android phone (unacceptable for music lessons, has no sound features, very spotty internet, small screen)

Electric Guitar:
A functioning guitar that has been approved by me via Zoom or by a repairmen or fluent player in your area.  I have run into alot of one stop shop guitars that simply don't work and then parents get frustrated as to why their child can't play it.  An average electric pack that is ok, I.E. amp, guitar, picks, cord and strap, is about 250-300

Acoustic Guitar
The same requirements as electric applies except only picks and guitar is needed.

It is good to get a couple sets of extra strings as they do pop and is completely normal.
