During the weekend, I will upload it here if anybody is interested in it.

Are you playing with humbuckers that you pull out the Volume 1 pot (pull bright)?
Also, the Treble pullout (pull shift) gives you "a more robust sounding mid range"... according to the II-A operating manual.
By the way, have you tried running the amp on the 100 watt position and plugging the JBL into the 4 ohm jack? It will sound a little darker.
Sorry in advance if I am saying something stupid.
