COLLECTION ONLYWhat it does mean is you have to ask yourself if the difference in quality is worth the difference in price. The G-400 necks are also considerably thicker which I don't like. Now, the G-400 PRO gives you the sound and look of a real SG without the vintage price tag and with the added tonal variety that you've come to expect from Epiphone. All-mahogany guitars can get a little muddy and boomy with the wrong pickups, but I think these are a really good fit. I can sit down and play it. The build quality of Epiphone guitars have gotten as good as it gets. So which SG would you go for? The reason I find this so exciting is not just because I have as deep a passion for CNC technology as I do guitars, but because this is a totally revolutionary approach to doing accurate fretwork and it’s accurate to the micrometer. No noticeable noise difference. While the G-400 certainly will never be on-par with the SG, it is a quality instrument that just might be a better choice for some players, and one of the best electric guitars under $500. Epiphone is a guitar company that is great at what it does, where Gibson is a great guitar company period. Joined: Jan 9, 2005 Messages: 15 Likes Received: 0 Location: merritt island,fl. All in all they sound cheap and lack definition and sustain and if you played the Epi without these mods with the strings catching the frets you will soon realise that your guitar has no sustain at all because of these factors. The SG Special returns to the classic design that made it relevant, played and loved -- shaping sound across generations and genres of music.
