I want to learn to play the electric guitar and classical guitar at the same time, but can only afford one guitar, so I’m buying an electric guitar. Which electric guitar would be best to learn classical guitar one?
Any are fine but you are mixing two totally different skills. The electric guitar is also thinner than the classical so your sitting position is totally different. It might make it very hard for a beginner.
Having said that, I guess you can switch later with some practice.
Guitar is HARD. VERY HARD. You might give up after a few months. Just getting you prepared so you DON’T give up.
I have a Roland amplifier for my electric guitar (a Stratocaster) and the Roland (cheap, under $100) has a setting where you can have it simulate an acoustic guitar. Gimmicky but you get less of the electric sound and can practice your "classical" tunes.
GOOD LUCK!
