Acoustic is generally harder/different to fret than electric. Keep that in mind.

Fundamentals are fundamentals.

That said, acoustic fingerpicking in the hauntingly beautiful exceptionally talented style of Jim Croce here (love this song, and Jim Croce RIP generally) is different technically and tonally from playing a Rock piece like John Paul Jones "Black Dog" played by Jimmy Page.

[br]But they share fundamentally in common they both use a selection of chords and notes played on six strings of a guitar. At our age, be guided by the tenet "One can do amost anything one wants, just not everything one wants". At some stage approaching the end of F2 when you are ready if not before, you'll know which and where you'll want to place your available energy and focus.

How you expand upon those fundamentals to develop further will depend upon what that decision of what you want to do with your playing, which will also be of influence in the type of guitar preferred if restricted to a single example. Nice to have an electric available for tone in the power chords lessons of Fundamentals, but your acoustic is fine to perform the tactile task necessary to have a hands on appreciation of the principles.

You'll 'know' when you're getting ahead of yourself when you can't do the stuff you've 'learned' previously to a standard of competency necessary to support your current point in the coursework. It's tempting to race through, but knowing isn't doing, the latter demanding perseverence in hands on application and longer for most of us in so far as learning guitar is concerned.

[br]Cheers mate. Always enjoy the journey, even in adversity.
