No need to over-complicate things.
Buy your V7 from your local store and tell your salesperson what you’re looking for: a headphones-capable amp for personal use at home.
Also, be sure to ask for a discount based on the bass/amp sale. Chances are you can get it.
The most important thing to do is to get a bass and take the Beginner to Badass course. There is no better or faster way to learn bass fundamentals.
