Last Tuesday, I took my 15/6/1 to a blues jam and paired it with the host bassist's Acoustic Image head for the night's backline. Local club with a full PA system and a guy hired to run sound. The sound guy has been down there every tuesday for the past three months so he knows the system.
It was cool to sit back and hear all the other basses and players that played that night.
As the rig was basically the stage monitor for bass, the volume was low to moderate on stage and the house PA had the room. Out in the room I got lots of comments that I would never have expected about my cab: "kind of muddy", "needs some mid range", "maybe you should get a 2-10". Moving around the room, the bass sound was varied, and the closer to the stage the better it got. The same guys who had issues with the bass sound sitting in the room, had a whole different story after their turn on stage. They were much happier after a "close encounter".
Long story short: your fEarful won't save you FOH if the sound guy takes your signal and turns it to mud in the PA. Worse, you can be a happy camper on stage, loving life with your fEarful doing what it does, and never have a clue what you sound like out in the room. Which is our usual lot in life, I know, and looking at the glass half empty. I suppose I should be thankful I'm happy with the sound I have on stage and count myself lucky.
I went back last night and we used the host's rig, same head and a SWR 4-10. Out in the room, the same fairly muddy sound. On stage, close to the rig, a better feel, but I missed the fEarful. The 4-10 lacks the bottom and seems to be super concentrated, with out much in the highs either. Still, an okay sounding rig for monitoring what you have going on on stage. With all the crap coming from the monitors and mains, you got the same muddy sound in the room.
The club is working on getting some new sub woofer cabs in, one of the old subs is blown, so maybe things will improve. Still, the room had nothing like the tight, full range bass sound I know the fEarful will do.
Anyway, if you get a chance to let some other folks play through your rig while you sit out in the room, and have a listen, it's well worth it. I should have would have lent someone the Dingwall to get a listen to the bass, but they all squinch up their noses when they see the five strings and the fanned frets. "Is that hard to play?"
