I have a tough time getting the bar to register on all strings so sour notes happen

You will be able to get real time feedback to make sure you are hitting the right notes

For example, if you play the wrong chord or a wrong note in your chord, you hear nothing from your jamstik

Also the bad notes you'll end up playing because you can't finger mute a string like a real guitar, instead you have to focus to not strum that string (mostly the low E).

If you play a fast paced song, the notes blur together and sound nothing like a real instrument, let alone the song

The low E had a similar problem, but was probably closer to dropping only 25%
