To start off with a clean tone, or to use the zillion gadgets to alter the tone ? The samples sound like an ultra pure guitar pickup sound. Pretty much exactly like an unmodified guitar thru a DI box, and certainly no 'better' for all your inconvenience and complications. The bland characterless sound the pretty much the whole world tries to avoid in an electric guitar. geoff

He made a complete idiot of himself on here last week and is in the middle of a tantrum as a result. Once his mummy changes his nappy he'll hopefully end this hissy fit. Until he gets over it and grows up a bit just ignore him. Phildo

Yup, you are absoutely correct. Using a dual pot to ground could potentially short out the mic preamp and the phantom power on the board. Never put that much thought into it as it made more sense to attenuate the unbalanced side.

Put the guitar back to stock, and run it into a Radial J48 or Pro48 active DI. |
