Maybe it is another Thomann?From mars or the Venus?
When I Google "Thomann Kemper Stage" I get this:
Number one in the category of "guitar preamps"..it is not that hard.And it is there since it appeared.Out of stick everywhere..
Twisting reality is the last resort for the desperate..
Within your logic everyone who wants "the best guitar combo amp available" (incl. tube amps!) has to buy the number 1 in sales ranking on Thomann in this category: The Harley Benton HB-10G
