I just have everything full on! LOL
Seriously though, using you rig at home with the intended gigging bass is obviously going to sound totally different to stage situation. Factors are;
1. Your ears are used to the sound in your home, your brain remembers the acoustics of your practice/living/kitchen/bedroom.
2. Do you ever crank your rig to stage volume in your house?, if you do you either have a detached residence or tolerant neighbours and have reinforced windows.
3. Most venues are acoustically crap, either boomy(the most popular), dead or too much reverb(except The Sage in Gateshead UK), there the battle commences.
4. Competing with the rest of the band, the acoustic physicists amongst us will tell us that the multitude of frequencies and sound levels are going to produce in/out of phase interference. Personally I have found keyboards the most problem as they have a massive octave range.
Is there a solution to all this?...I try and get to the gig before the rest of the band and try and I emphasise the word try, to get the tone which sounds okay..it will never be perfect.
We seem to have all sorts of electronic add ons to help but even they can be a hindrance.
Sometimes less is more!
Oh yes, then if you go through a PA and monitors..well you are at the mercy of the sound engineer...a never ending road!
