Buying a large combo or (especially) a stack for the purpose of wailing in your living room at all hours can lead to divorce. So can spending $2000 on an amplifier without telling the wife (because you know she's going to say no). As a general rule, guitar equipment is to be treated as if family members had a restraining order against it. It doesn't matter if people pay good money to have you assault their eardrums with your frenzied solos every weekend, nobody at home is going to want to hear it. Whatever type of amp you buy, headphones are a must for home practice. Similarly, if you plan to install an enormous Marshall stack in your garage for rehearsals, make sure it's a detached garage. The Mrs. doesn't want to have Black Sabbath's "War Pigs" rattling windows and knocking pictures off the walls while she is entertaining her Saturday bridge club.
