You can have gapless now, just use 1 amp channel, and scene controllers to vary the gain as needed between scenes. I primarily use the BE100 amp, but any decently dynamic amp should work. Using scene controllers to vary the gain from about 40% to 70% with a boost from the preamp section of the amp block covers a LOT of ground. Combined with a filter block for a solo/volume boost on its own scene, I can go from nice and chimey clean (backing down guitar volume) to fire breathing solo tones - no gaps.
