Well the thing is that everyone should (in most cases) use a different EQ setting at gig volumes than at practise volumes. The reason is something known as the Fletcher-Munson effect. Basically, this effect describes the differing perception of sound at different volumes. At low volumes, notes of a low frequency must be played louder to be percieved at the same volume as notes of a higher frequency. Mids are percieved as being the loudest, with treble slightly quieter (but still louder than the low frequencies). As the volume increases, these differences become less pronounced with lows and trebles being percieved at a similar volume and mids only slightly louder.
It is this effect that is the reason for scooped mids sounding quite good in the bedroom, but relatively shitee when the amp gets turned up.
What you will find with your settings is that as you turn the volume up, it will start to sound different. The way to solve this is to turn your amp to gig/band practice volume beforehand and EQ it at high volume, as this will take into account the Fletcher Munson effect (and will likely sound horrible when you turn your amp down again) and will be the sound you want for your gigs
Sorry for the long post, and I probably made it more confusing than it needed to be - but if anyone's interested, ask for more detail or just google "Fletcher-Munson effect" :drink:
EDIT:
This is an "equal loudness curve". It shows how loud a note of each frequency has to be played to sound the same volume...As you can see, bass notes need to be louder to sound the same as notes in the mid frequency range
