..and I was wondering if any of you have experienced anything similar or have some advice for a new Mark V owner. I will cut and paste my email that I sent off to Mesa this morning to show my problems.
I am having a few problems with my new Mark V head. I have one by one replaced all the preamp tubes with a known good to try and diagnose these problems with no success.
1. The reverb when on in channel 1 has a very noticable buzzing/hum sound.
2. Channel 2 when the EQ is not engaged has a loud persistent hum.
3. Anytime the EQ is engaged or disengaged, be it with the footswitch or front of the amp, there is a very loud thump sound that hits you in the chest.. This is not a small channel change type thump but a very loud one.
Any advice would be greatly appreciated!
