I have my HD500 connected to my DT25 via L6.. However I have decided to use my blackstar amp in tandum via the 1/4 output.. My problem is the volume levels are wildly different. I have to almost max out my blackstar volume to match the L6 connection on the DT25 at just a moderate volume.. Is there anyway to increase the 1/4 output to more closely match the L6. this isnt a patch issue this is across the whole spectrum. or am I trying something that shouldnt be done?
