Yes.Anyone tried a 12at7 or 12au7 in the Space Heater?
In both my OG SH, and my LEHW SH.
I was looking for more "clean gain" with less compression.
I put an EHX 12AT7 into them.
Bothe units don't have the trimpot of the later versions, so they were always very loud.
Combined with using high output basses, things would get "too much, too soon"
The change brought the output and response more in line with what I wanted out of them.
