I just joined the forum about a week or so and have already gotten some good advice on a reverb problem that I was having with a Mark IV A short Head that I recently purchased.
I have completely retubed the amp with stock Mesa pre-amp and power tubes. It sounds great and is working fine except for the three presence knobs and the pull shifts on R2 and LD. None of these have any effect on the sound being produced by the amp. I've read all the posts relating to presence controls and pull shifts and didn't find anything that might give me a clue as to what is wrong here.
Unless some of you can come up with some easy fixes for a non techie, I'll have to bring the amp to a tech and let him have a go at it.
Thanks in advance for your attention to this matter.
