I just wanna record guitar so shouldnt i just by the simple Line 6 POD GX instead of the POD UX2. Will the effects or quality change? Thanks!

to my knowledge the quality will not change at all (i have a PODstudio GX).. the upper level podstudios just offer extra inputs for mics and such, which will give you higher quality vocals but will not effect your guitar or bass tone.

i definitely love my GX too its totally worth the purchase!
although i recommend not using ableton live (recording program) that comes with the podstudios... in my opinion the sound quality was downright AWFUL (although it could be just on my computer). I suggest investing in a different program or using Audacity which is free (i use this because its free and doesn't alter the tone coming out of the podstudio/podfarm application)
