Headbanger1978

I tried using the new PVpanama blue and red preamps and can't get any usable volume. I have all the volumes maxed the helix has to offer into a peavey classic 50/50 tube power amp maxed. The sound isn't at speaking volume level. I do not have this issue when using the full amps. I don't have this problem with any of the other amps or preamps. I've reset the helix, tried using empty presets that's never been used with no luck. Even tried using just the preamp without any other blocks.
