Never judge a player for having a cheap bass.
Alice Coopers bassist uses an Epiphone Thunderbird
Alvin from UK Subs uses a Squier Jazz as well as his Fender and he is fecking brilliant.
Matt Freeman from Rancid has a Squier P bass as his backup and he's one of the best bassists in rock.
Mike Kerr from Royal Blood still uses his budget Gretsch Electromatic even now thar Fender give him their top kit.
Judge them by how they play, not what they play. Just because someone is skint doesn't mean they can't play and just because they've got the money for fancy kit doesn't mean they can shred.
