Haha I hear you...I have opened the mic so many times to try out stuff that I might need new screws soon. For the ef184 I have replaced the 100k plate resistor with 51k and went back to 100M grid resistors. First session tomorrow with this configuration so we’ll see how it behaves.JMPGuitars said:I ordered them on the 15th, and I'll still probably be waiting another month for them to show up. I'll probably wait until then to test other things like the EF184. I hate how annoying it is to take apart the U47 body, and I love how it sounds anyway with the EF80...so laziness wins.
