Sorry for the click-bait title, but I couldn't think of anything else. So here's the long question. For example. In a mix, could you tell if the guitar played was a $800 Epiphone Les Paul or a $3,000 Gibson Les Paul? I'm thinking about it and I'm not sure. In a studio, I think other things blur the line. A various high quality tube amps, speaker cabinets, mics, mic positions, mic pres, EQ, compression, ect. ect. After all is said and done, would it matter in a mix? If your Epiphone feels just as good in your hands as a Gibson, does it justify upgrading? Maybe upgrading pickups, but still that might not even have a huge impact on the final product in a mix. Hell, we have to read in a guitar magazine what our guitar heroes used on a particular album because we couldn't even guess if blindfolded. What do you guys with experience think?
