Hi! I enjoy playing both electric and acoustic guitar equally. What would be the most effective way to practice each instrument , one day on an electric guitar, the next day on the acoustic guitar or split the days practice in half between the electric and acoustic guitar. I practice between 1 hour and 1.5 hours a day.
Thanks
It doesn’t really matter, as long as you are practicing. I would equate it to practicing standing up vs. sitting down.
I tend to practice skills that are more likely used on an electric (string bending, palm muting, etc.) on my electric, along with songs that I plan to play on electric. Skills for an acoustic (picking individual strings while strumming, percussive hits, etc.) on my acoustic. When in doubt, just play the guitar that’s in your hand at the time.
YMMV
As long as you are giving them both a fair mix, you should be fine. The issue would be if you favor one or the other for a longer period of time, you will lose the other skills over time.
Example, I often play acoustic live but I enjoy practicing on the electric. After a lot of practice (on electric) I noticed a lot more fret buzz when I played live (on acoustic) than I was expecting because my fingers were not used to barring the acoustic strings. Consequently, I make sure I am getting an good mix in practice. For me, that is mostly acoustic and electric maybe a couple times a week. Alternatively, if you practice more acoustic, you might find yourself pushing too hard on electric and bending strings out of tune.
In any event as long as you are regularly practicing both, they will certainly benefit from one another.
I make a point of playing both daily. That’s not to say that they always get equal play time, but I want to keep the habit of playing both regularly.
Also my preference for practicing skills is daily, even if it’s not for long, so if I was practicing a particular skill on one guitar then alternate days wouldn’t work so well even if I practiced for twice as long
I’m no expert guitarist, this is just how I practice
Seems like a good question David.
Myself, I got three guitars I play regular. 2 electrics, 1 acoustic.
I keep my guitars in their cases when not in use.
So, pretty much each day I choose a different guitar. I just rotate through them. One guitar each day.
Of course this don’t always work. In the summer especially. I like to play on my back stoop so it’s easiest to take the acoustic outside so that’s what I do. Summer time the acoustic gets more play time. Winter I suppose the electrics get more play time.
fwiw, I also rotate through 3 amps, same way.
I can get many different tones going this route. Keeps me interested this way… 
Last thing I’ll say is. If I’m working on a specific song I may play what’s proper for the song in question. If it’s an acoustic song, I don’t play electric. Visa versa. But then again, to mix it up, heck, I’ll play elcectric on an acoustic song, visa versa again… 
Just mix it up man and stay interested…
I’m still rather new here, (at the end of Grade 2) so still learning lots of new stuff. I find learning the techniques on electric first to work best for me. Maybe because I’m just more comfortable with electric, haven’t had my acoustic for a year yet and until I changed strings a week ago, it was very hard to play.
As for learning songs, I also tend to learn them on my electric but then I find some just seem to sound better to me on acoustic, John Denver’s Country Roads for example. Yet so far, most CCR songs I’ve tried sound good on both.
I’ve been averaging an hour a day lately and try to make sure at least 20 minutes is on my acoustic.
I play totally different songs, for the most part, on acoustic and electric. I prefer to focus on one genre/instrument at a time. Seems more efficient to me, but that’s just me!
I tend to split my practice between my 4 guitars 3 electrics and one acoustic if the original song was on acoustic then that is what I use or if its electric then i tend to use electric but whatever you use its playing which is good
Like LunaRocket I learn new skills, songs etc. on my electric and then move to my acoustic which I play 2/3rds of the time.
In my experience it is best to split the time equally. Not particularly in one day but maybe 1 week electric and the next acoustic, works for me.
