A co si myslíte o Mesa Modu? Myslíte, že koupě součástek za pět korun a hodina práce můžou tak razantně zlepšit zvuk?

MESA mod
It makes the gain channel million times better (exaggerating).
Mesa and Bogner like (Not exaggerating).

Remove R122 (no jumper needed).
Leave R124 in place (Don't touch it).
R116 to 10k (Wattage don't matter here).(10K has more gain, 22K has less... tightness of tone depends on EQ and setup)

The tone stack cap & resistor are crutial to Mesa sound;
C2 to 470pF
R4 to 47k

If it's too dark remove C149 (cut one leg of it).

50/100W Switch (VK100/212 ONLY)

Here's an idea lifted from Mesa/Boogie Lonestars, very simple.

If you remove the Texture board, you can have something better, imo. Save the 100n cap (C1) and install it in series with the 100n cap (C144) on the power amp board. This closely matches
the other side of the splitter (C135 47nF). Alternatively you could replace the pair with a 50n cap. You must use this set of caps to bridge the gap left by removing the Texture circuit. Refer to the
VK100/212 schematic for details.

Once you've accomplished this, throw a DPDT switch in its place. Locate the cathode jumpers for either V7 & V6 OR V5 & V4, pin 8. Take a lead from the pin 8 side of the jumper from each of the
two tubes you've chosen and run each of those leads to their own contact on the switch. Take the ground side of the jumper, or just solder to that fat ground trace and bring that to the two common
contacts on your DPDT switch.

What this does is disconnect two of the power tubes, one from each side of the push/pull, and deactivates the cathode ground. This is how Mesa does it in the Lonestar 100W series.
