Using this setup: O^O headphones <--+ | guitar >----> HelixLT <---- USB from computer playing backing track I'm trying to play with tracks supplied from my computer via USB, using the headphone jack to hear the mix. However, the volume of the backing track coming through the USB is too low. I can use the volume pedal to lower the volume of the guitar, but I'd rather start by getting the mix right in the first place. Is there a way to modify the volume of the audio input to the LT from the USB? The audio output level from the computer is already set to the max. Thanks and regards ...

That button is pushed in. I don't know if that means ON or OFF. The only place I can find it is in the Pilot's Guide. It says to push it if you have hot or active pickups, but it doesn't really say what it does with the button IN or OUT. It only says, "Use what sounds best." I had to rehearse last night, so I didn't have an opportunity to perform the loop test. I'm cubicle bound today, so I'll try it when I get home.

New About 2 months. No, the amp models never had any volume from day one, except for the Line6 models All of the following: * Headphones via the headphone jack on the front panel * Plugged into a Vox VT40+ amplifier via 1/4" output jack. * Plugged into a mixing board via both XLR (stereo) * Plugged via USB into a DAW running on my W10 desktop. I've tried this with no joy. What is "guitar pad"? I will try this today, when I'm off work. If I get better results with this test, what does that indicate? I haven't tried the resets, yet. I'll try them today and let you know. MANY thanks for the helpful response!

I did this, and it seems to work. The Boost Comp, however, lists its controls as percentages, not as db. I would find db more useful. Perhaps that's a global setting somewhere.

Yes, I have both set to LINE. I get the same results whether I use headphones connected to the front panel headphone jack, or the USB to my DAW, or 1/4" backpanel output, or XLR backpanel output. As I said to stormstudios above, the only amp models with any appreciable volume are the Line6 ones. Hmmm....

The setup is guitar in to the Guitar jack on the front panel. The signal strength of the amplifier models is very weak, regarless of whether the output is 1/4" front panel headphone, back panel 1/4" or XLR (stereo), or USB to my DAW. The only amp models with any appreciable volume are the Line6 ones. All the others are barely audible. Ok, THAT's very interesting. I will try using a Boost Comp with 12db in front of the amp models. That's a significant boost, by the way, and I'm surprised that it is necessary. Many thanks for the response!!

All the amp models in my Pro X have very low volume output, and what little volume they have is hideously muddy. Right now the only thing in my signal path is the amp, any amp, and they all sound crappy and have no volume. Some amp models have no detectable volume at all. Doesn't matter what I do with the drive, volume, and master knobs. What am I doing wrong?

Never mind. Figured it out. ABCD mode gives me 4 presets.

Can the FVB Express Mark II be configured to select presets instead of just individual effects in the chain? If so, how? I wasn't able to find anything in the documentation.

I am having the same problem. I'm thinking of returning it because of this.
