Gents, I have an '86 "black stripe" Boogie Mk III that I really dig. However, now it seems I have encountered a problem with it. I turned it on today and discovered that I'm lackig a lot of volume. With the input volume at 7, lead channel volume at 10 and master at 1.5 I was hardly getting any sound out at all. Usually this would be very loud. I had to turn the volume up to 3.5 until I was getting a good volume. Normally 3.5 would create vomit inducing sound pressure levels.... something is wrong. What? I also plugged my delay into the loop. When I switched the dealy on I lost all volume again. Weird! Can anybody help?
