Hi, Would appreciate some expert insights. I purchased an Epi Blueshawk recently and am really liking it. I do find that regardless of pickup selection and with volume on max, as I move the varitone select from first position ( basically no varitone effect) to the remaining positions the volume starts to drop off incrementally and the overall volume drop is pretty significant, especially in the 5th and 6th positions. If I have it in the 6th position and then pull the tone knob up to deactivate the circuit, the volume comes up where it seems to belong. Prior to purchase, when I checked several different reviews of the BH on youtube, it seemed nowhere nearly as pronounced as what I'm seeing. Is this normal? Has anyone else experienced this and found a way to resolve it?
