It's not the number I'm looking at really, it's the reasons.
I have found and have been told a bunch of times by FOH engineers that they usually HATE it when we switch from say a Jazz to a Music Man or something to that affect.
The only time it works for me is when I'm working with someone where the FOH saves a different "scene" for each song in the set (automated board), so the mix will compensate for changes such as bass changes ect....
The thing most FOH engineers say is, the bass is basically one of the most difficult things to sit well and actually be heard in a live mix. And it doesn't help their cause when we switch, or use a lot of effects.
One guy who I was on the road with really helped me and I ended up having the best FOH tone I think ever (and from there on it always sounded better as well) when he asked me to play a whole show using one bass- unless I had to switch because of a string break or something.
Also to not touch any settings after the second song.
His philosophy was give him a consistent even sound that doesn't change and he doesn't have to fight me with the rest of the low end in the room. He can actually get it sounding good.
It's like the kick drum. Usually at most shows the kick pretty much always sounds good. Because it's low end that doesn't really change at all. So it can be dialed in and it will sit good all night long.
Later on the tour, because they changed some songs out of the set, so I had to switch basses a few times, he actually gave me two channels on the board.
When I would switch, he would mute on and un-mute the other. Each was set for their respective bass.
Also leads to another question that stems from my above experiences... How do you sound check????
Play a bunch of scales?? A slappity solo piece??? Randon licks up high???
I did some of all of those for a long time when I was told to "Hey man, stop for a second and play me your low B".
I did that and then asked to play my low E the A and so on.
He didn't need to hear a bunch of random notes, he needed to hear some "bass".
So now, for sound check all I do is play open B, E, A, D, G, D, A, E, B....
Then I play about as hard as I'm going to play on my B & E. Which is damn near how I played the open strings anyway.
Unless I'm doing a funk gig where I'm switching between fingerstyle and slap, I keep it simple.
I've been told countless times by FOH guys that it was one of the best "Bass sound checks" they ever had to work with.
