Yeah, that's the problem. They stop updating it.The G5n has IRs built in (cannot load your own). I almost exclusively use the Bogner one, it sounds great with every amp.
The G5n hasnt received new effects since april of 2018
At the moment, I'll go for the Mooer GE 200 for better amp modelling & a good interface. The Zoom units have better effects.
And there'll be something better later on. I'm good with my pedals < 150 $ & 2 SS amps for another 100 $.
