daveyball Posted January 7, 2017 Share Posted January 7, 2017 Hey I'm using the 4 cm method template on the helix to go into my Marshall JCM 2000 60w amp. When I switch the helix preamp to switch the loop out and the pre amp on, all the volume drops. Any ideas Thanks in advance Quote Link to comment Share on other sites More sharing options...
ricksteruk Posted January 9, 2017 Share Posted January 9, 2017 It's probably because the level gets boosted by going through the Marshall in the FX loop - the Helix FX send should be sending INSTRUMENT Level to the Marshall Front Panel input jack, and then the Marshall FX OUT sends -10dB (or some do +4dB) level to the HELIX FX Return... which is basically line level. So you get a large increase in volume. What I do is set the Return level on the Helix FX loop Block in my patch to about -18dB, so that when I bypass the FX loop the volume doesn't change. I usually try to test this out with a clean & loud tube amp setting so that it's easier to tell if the volume is the same when I bypass and engage the Helix FX block. Then after that I dial in my tube amp to a more dirty tone and then set up a Helix amp block and set the channel volume so it also matches with the real amp as bypass the block.
