James, if it's got the tone you're looking for, you MUST do it. A lot of great guitarists get their distinct tones from a unique amp setup... Hendrix, EVH, Tony Iommi, Josh Homme, etc. If you can get your own unique tone, use it and MAKE it YOUR tone...
...and one day Carvin will make the "JamesL R600G" 600 watt guitar half-stack and sell it for five times what you bought it for back in 2008. :icon_thumright:
