well, epiphone, Ibanez starter guitars and Squires deffinently, proffesianally is EASILY GIBSON
fender or gibson and then ibanez..... even though dean will endorse anyone, their popularity is still small.
I think Fender is the brand most sold in the world followed by gibson, ibanez ,esp, and psr, but that to be the best selling brand does not diminish the quality of the other brands mentioned.
Jackson probably would have been higher before the fender takeover and half their roster leaving. That and people realising that ESP just crush them.
