I am running my Helix into a Matrix GT1000FX amp. I was using this with a Fractal Axe FX XL. I don't seem to get the same amount of volume out of the Helix. I am running the Matrix into a Mission 2-P 2x12 passive speaker. On the clean tones I almost have to dime out the Helix and the Matrix to get decent volume. I'll have to recheck my connections but I think they are good. I am using Mogami XLR connections from the Helix to the Matrix and Speakon from the Matrix to the speaker cab. Any suggestions would be appreciated. Thanks.
