Yup, I've seen that in workbench but I'm looking to see if there's a software solution to adjust the volume of the entire bundle in one shot, or if there may be an adjustment chip on the motherboard in the guitar itsellf, et. al.

Thanks anyway!

Interesting...

In your case bearman, even if the string volumes are at 100% it still won't be enough. From the answer so far, the only way I can level off my models is by using the string volume for each model in global mode in workbench.

I would think that in theory, there is something you can put in the signal path of the pickups or modeling electronics to antennuate either one. But that would probably take a skilled electronics person who knows what they're doing with Variax components. And it would probably void any warranty.

Although an SPL meter would be an accurate visual check, I've found that even with the amp models, I have to "road test" in working situations, then tweak to dial in the proper "perceived" loudness of each model. But I'm sure you could get pretty darned close with the meter.

I used to have a pocket sized Korg guitar tuner back in the day. As it turned out, it was incorrectly calibrated at the factory and off by a few cents. I opened it, and there was a component on the circuitboard that let me calibrate it with a jewler's screwdriver. I was hoping to hear that the circuitboard in the JTVs has a similar type of output calibration device in it too, or something along those lines. That way, a certified repair person can make some quick adjustments and keep the warranty intact.

I am curious to hear from L6 techs to see if there is any calibration/cross calibration going on during the assembly/QC process. Is it even a consideration? Based on these two opposite cases, I'd be surprised if it is, and they're getting that kind of swing in quality control. I'd also find it hard to believe that L6 would make circuits without any way to adjust the overall output.
