Nope. Your friend just doesn't like the amp and this is the excuse for not using it. I'd bet hard crypto on it. I don't understand the main question of this thread. Bassists have been using customs since the early days of bass guitar (Stanley Clarke, John Entwistle...) So yes they can be your daily driver... They're exceptional instruments, why wouldn't you. The "daily driver" description starts a false comparison between instruments and cars, when there is no overlap. A Ferrari is not analogous to a Fodera, and a Fender is not a Ford. There should be no comfort issues, or tonal difficulty with a high end instrument, otherwise you are wasting your money.
