Hi,
I would still prefer to be in for the full 100 watt head. It will simply replicate the sound of the artists better.
By taking a look at my original post, I still think it is a great idea:
Take the JJ with the Butterslax knob layout
a. leave clean as is (JJ Clean)
b. JJ channel as is incl. JBE switch
c. add the third channel of the Butterslax (extra gainstage, different voicing), Gain and Master controls
d. add a diode switch to remove the diode clipping for channel 3 (which will give you kind of a HBE, I guess)
e. make the extra Gainstage in channel 3 switchable (which will give you "BE/JBE" in channels 2 and 3
The only drawback I see that there is no overall master in this setting.
If I may add one thing: Make the loop switchable.
@Dave: What about a JBS
