Hello. I did mesa mod on my valveking amp.
Here is the schematic:

And all is OK!!! Just equalizer settings are worse than before. The sound had a better gain, and overall the sound was more agressive, but highs and mids disappeared. It sounded cool, but with too much bass. I noticed that, when I plugged in some effect to the FX loop, mids and highs are back! And also when the effect is turned off, mids and highs are there again. So I tried to plug only one side of cable to SEND and second side to RETURN, witouth effect, only cable used, and highs and mids are still there. Weird. Now when I unplug that cable, then mids and highs are lost. Gain is without problem. Sound stays more aggresive and more gained(highgained). How is it possible, that mids and high appear only when I plug any effect to the FX loop, or without effect, just by connecting SEND and RETURN by one cable? Thanks a lot
