Never thought about thatIt’s a very small industry. And only a few companies do enough business to be able to throw a lot at marketing and neither of them needs the ads to attract customers.
If you’re a Strat person no amount of Gibson ads would make you change, or Yamaha ads wouldn’t make you think of giving up a Tele.
Also every professional broadcast reporter has a Strat hanging in their office. Is that really a coincidence? No reporter on any network has a Les Paul?
