I just got my Hematoma and have been giving it the go around. I am using it in the front on my G-K 800rb and tried it throught just the effects loop in to bypass the GK pre. The pedal sounds good on the overdrive side but on the pre only side I get a drop in signal like a 5db cut instead of boost. Do I have a defective pedal or am I not using it right? When I turn up the big chicken head all the way and have only the pre "BP" side ingaged my rig is louder when I turn the BP off. If I kick on the OB side all is as expected.
