Basically i have this guitar rig 2 software that lets you plug you guitar into your computer and use effects, the thing is you cant set the program to use the LINE IN port as the input only the MIC port. My current sound card is just a standard one inbuilt into my motherboard with 3 ports MIC, LINE IN and LINE OUT. But when i plug my guitar into the MIC socket the sound is very poor and crackley but through LINE IN the sound is OK. What i want to know is is there a soundcard specifically for instruments or guitars whether its plugged into LINE IN or MIC port. (I have tried messing eith all the Mic volume and all that but the sound quality is still messed up) I need good sound quality even through the Mic socket. thanks guys!
