No.
But I have a line 6 toneport interface. And have a little experience with guitarists using Line 6 stuff.
Just my opinion here, and it's not based on a ton of experience, so I'd like to hear other take on this also. My somewhat limited experience however tells me that line6 has their heads up their butts when it comes to bass stuff. They nailed the guitar fx amp modeling technology, but anything bass related, to me, has been useless. When using the line 6 interface I stay away from all their effects and models, and use other preamps and effects before and after recording.
Pretty sure their bass amps haven't been all that much of a big hit either. I hope they're looking into upping their bass game, but I get the sense they're all about guitars.
