I am wondering if there is such thing as a "software preamp" you know so I can plug in my guitar through a 1/8 1/4 inch adapter to my mac without the taking an actual preamp everywhere.
If you have a mac you should have Garageband, which has built in amp simulation. Although I would recommend the Line 6 Toneport. It sounds good and is portable.
the thing is that it does not sound all that great, constant hiss and very weak signal.
