Hey guys, I'm looking into purchasing a guitar amp, specifically for recording. I'm wondering higher watts will have any effect on recording quality. I will be using the record out jack they have on the amp, not micing it. Also, what differences am I going to see between the Spider III and Spider IV? The only difference I could find was 4 additional amp models, and 50 more presets. Are there any other large differences in these two models? How will the quality sound using the recording out jack, to a USB 2.0 preamp, to my DAW?
