another curious question. Since people seem to like using GR4 for re-amping. What is the allure about re-amping? I always felt that amps kind react to your playing. So if you play something not amp'd or through a diff amp, you would play it differently than if you were playing through the actual amp that you wanted in the end. So the performace would change depending on how the player feels the sound of the amp reacting.
Great example for me are rectifiers. The feel totally different to me than other amps. that"sag" feels almost like a delay to me. so i play differently than through a 5150 or whatever
