Good morning!
I have a Tweaker 40 head. It had a Mercury PT installed at a shop last year. I installed new power tubes and set the bias. The amplifier seems to be powerful, all the switches and knobs work fine but no matter what I do when playing with any sort of distortion it sounds like the mids are scooped, or like it is under water, if that makes any sense.
Is this something a preamp tube upgrade could cure? Is there something else I can look at.
I am able to do very basic electrical and soldering work if there is something I can add or subtract from this unit.
Thanks for any help!
