That mod seems to work fine. You can also put a volume box in the loop (search fleabey), tehy only cost 15$. The legacy's master (there is no), is always on 10. just not so practical.
it's not to be compared with a line6 amp. The legacy's clean is so full and warm. Although, besides my legacy head I also have a pod X3 live that I use for practice with headphones.
I also have a Atomic Reactor 50-212 amp. THE nr modeler amplifier, I'm planning to sell because I don't use it besides the legacy and my 9 months old daughters room

), so if you're interested, I'm going to put it up for sale soon, pm me.
