Mesa Boogie Fillmore 50 Watt

Went to GC to buy a guitar and amp. Told the sales man that I have zero knowledge on amps/pedals etc and that I’d be a bedroom guitarist forever. He told me the Mesa Boogie was for me so I bought it

Just talked about this with guitar instructor and he said that the amp is overkill and I was taken advantage of. He also said that I should have gone with something like a Katana.

Seems like he maybe right here. Should I sell the Boogie and get something else? Thanks for any advice
