When I got my Forte I loved the OBP2 tone in it.
It had what I guess can be described as
a "clean wood like growl"
But my S.A.S. for the Spector 9Volt USA circuit (Haz) wouldn't get out of my system. (I blame Patrick

)
So I decided to add the Spector 9Volt USA circuit (Haz) and I fell in love even more.
"True story", which I have mentioned before to some of you, when I finished installing it and I played the first few notes, I started to make "moaning sounds" from the excitement of how great it sounded. My wife and daughter seriously thought I was have a some type of cardiac episode and came running up to see if I was ok.
Here is a sound comparison. Both of these clips where recorded with DR Hi Beams which are the strings I had on it the day I swapped the preamp.
