Work for car dealerships for 25 years. I know how trade in's work & they never ever benefit the person trading in the car.
Ever trade in a car? Do you think they're doing it out of the goodness of their heart? How much did they give you vs. what it sells for on a lot?
Some people HATE selling privately, and would gladly trade their amp in on a new one, instead of having to move it themselves.
Was not trying to bash Two-Rock just wondering how this would effect the used Two-Rock amp market. IMHO I think Two-Rock is most likely more accurate on what these older amps are worth used then the private seller.
