Line 6 hasn't learned from any of the spiders... 1 through 5. Not sure why they would suddenly learn something from V to VI.I imagine Boss will be planning on redoing the Blues Cube line and possibly Katana Mk II soon enough.
GT-1000 DSP, better power section, poplar cabs and Wazacraft speakers will all help cement them as a potential market leader in affordable, SS amps. They need to have a loadable IR for the DI/headphone AND need to actually be editable via Bluetooth and have a decent PB (not the GA-FC) option. Not being able to edit on the amp is a huge PITA.
I do though feel that Line 6 has been paying attention and believe that they will soon (now the HX Stomp is a reality) release a SS amp based on their experience with the Powercab+ and HXS. So Helix level DSP and amp sims inside a Powercab+. Sort of their version of the Kat Artist. I think they have learnt from the disaster that was the Spider V and can make a killer digital/SS amp.
It will be a good time for SS amp lovers.
They could both learn something from the Orange CR line.
