Hi
This is my first post here and I hope some one can help me. I have a Boogie Mrk IV combo 2003 I have the following problem, when I switch on the boogie I get a Loud Humming
Sound from the speaker if I turn down the reverb the Humming stops, when I say Humming this is a very loud Humming. I have had the valves changed recently but only the small ones
The four large valves were not changed, if I play with the reverb turned off every thing is normal
No jumps in the volume. Lead rhythm and clean all as expected no cracker ling no fuse blowing just Boogie heaven. Thanks in advance.
