Long time lurker, first time poster! So I just picked up a Shuttle 6.0 and a NeoX 212T and I'm loving the tone. I know a few people here have the same rig and feel the same way. However, I was wondering if anyone has run a Shuttle 9.0 or another (more powerful) GB amp with the 212T and if it's worth the upgrade. In other words- what's the best amp for the NeoX 212T? Cheers!
