I purchased both the acoustic and electric Paul Frank models and my son absolutely loves them. He is only 4 years old, and he is not doing the flash cards yet, but he does have good form and is leaning to pick strings and press on the frets.
We bought the pro electric for our 5 year old son. He already had the Loog mini acoustic and we took a chance on the pro considering it says ages 8+, but he wanted an electric so we went for it. It is AWESOME. He can play it just as easily as his mini. It looks so cool, we love the Paul Frank graphics. It’s very well made. We were worried that the amp wouldn’t sound good but it sounds great! It’s so easy for him to plug in and play, and take it with him to lessons. His teacher was impressed with it also. We would highly recommend any Loog guitar!
