I totally agree with you that the Katana sounds great! The other guitarist in my band was gigging with one for a bit, and he always had a good tone with it.Thanks all, the only thing I know is I love it, it rocks, it's groovy, and it services me well.
Why would Boss emphasize solid state other than to scramble that simple chunk of fat in my head.
As far as why Boss would do this, I think it's pretty simple. I think when they launched the Katana series, there was still a lot of cork sniffers (myself included!) that looked down on modelers. While that hasn't gone away, I think there's way more acceptance of them in guitar world. So they were trying to use buzz words like "analog" to attract players who otherwise wouldn't consider it. And then just like other companies' entries into modeling, Helix, Iridium, ToneMaster, once people tried them they genuinely liked how they sounded. And now while the stigma is still there, the technology has REALLY proliferated among serious professionals who tour and record for a living.
