You need chorus. Check these
I would choose Squier. If You need humbucker, check theseYou should check also Yamaa Pacifica. It's great altrnative for Squier and Fender.
This guitalele probably was with nylon strings, am I right?Try with nylon strings guitar. These are great fo beginner
There's definitely chorus in this tone. You can try with one of these if you want.But i hear also pitch shifter, but i'm not sure.
I would chose Nova. It's very verstile delay.I can recommend You also Obscura and Flashback
Problem solved? I had smiliar problem and noise gate helped. Try one of these
