You can dial in your DISTORTION...of analog tape or tubes......digital is better, see, it's pristine, why would you want to dial in DISTORTION, then have reviewers claim this or that DISTORTED playback sounds so good, by having more tubes in teh playback end adding more distortion to the already tuned DISTORTED signal at the recorded end which was from tube amplifiers in teh guitar amps.....how can tubes be better than SS, if they just keep adding to the blend, but this thing looks cool, if it mimics it all, but then so does guitar stomp boxes, all adding sounds, it's endless.... http://www.cranesong.com/hedd192.html
