Re: Carvin vs. Ibanez
Carvins are great guitars. You should note some very basic differencees between Carvin and Ibanez, structurally speaking:
1 - The Carvin DC models are all neck-through-body.
2 - The Carvin DC, V22, and UltraV, models have a 25" scale lenghth, as opposed to the RG's 25.5"
3 - Carvin's Bolt-On models (Bolt, Bolt+, and Contour66) are 25.5" in scale length, but have 22 frets and a bulky heel.
4 - Carvin's CS, CT, and Holdsworth models are set-neck guitars.
5 - Carvin's necks are a bit thicker and a tad more narrow than Ibanez necks. You have a choice of radii - 12" (standard), or optional 10" or 14". The 14" will be closer to what you're used to if you've been playing Ibanez.
6 - Carvin uses the Original Floyd Rose trem on all models except the 7x7 series, which feels and sounds a bit different than the Ibanez Edge models.
There certainly are many other differences, but those are the most glaring. If you want to build a Carvin that's similar to RG specs, then for for either a Bolt+ or C66 with the flatter, 14" radius. If you have to have 24 frets, then go for a DC model with the 14" radius.
Take a long look at the options available and even call the customer service number - those guys are really helpful.
(no, I don't work for Carvin - I'm just a devotee)
