Hi Guys
Having the extra tube positions is much more versatile than replacing them with GMX. The tubes can be any type lending their tone character as well as the GmX effect.
In a super versatile format, each output tube can have its own level control, allowing any mix of the two sides of the circuit with whatever tubes are fitted. PA66 uses a tonally asymmetric splitter, so even in a same-tube situation, reducing the drive to one side of the circuit has a different sound than reducing it to the other. The panel control allows access to both sounds. Adding a Body control to only one side allows accessing the tone of the other side and dialling that sound all the way to an SE (single-ended) tone. But... if the Body control itself only works on one side and there is only one such control, only one range of tones is accessible (for same-tubes).
Two Body controls "fixes" the above inasmuch as the tonal range of each circuit half can be accessed. The same applies with a double-ended Body control, as I had on the later hand-wired amps. I have some custom pots on order for a newer version of the double-ended Body control to go on some amp designs in the works.
So, Vostre, maybe you need to make room for one Body control? Move the footswitch to the rear.
