there is at least one alternate path --- if yer willing to haul everything 
dual mono or 3-point stereo:
gtr> knucklehead> dedicated knucklehead cab
(line out of knucklehead> small mixer)
(gr-1> small mixer)
(edp's on fx sends @ small mixer)
(small mixer out> power amp ins of 1 or 2 jc120's)

this separates the tone and soundsource of the gtr from the synth and

sounds reasonable, but then you'll not be getting the best out of the 
knucklehead through the 'high-efficiency' jc-120's, i think.....

right; and most dummy-loads still require the amp to be connected to an 
actual speaker cab.....

quick answer:
well, there's no quick answer to that.
if you wanna maintain the sound of yer kh, yer gonna need to play it 
a suitable spkr cab.
i have, myself, a few pathways to that end:
1) my current setup uses the thd hotplate: very good-sounding & reactive, 
very flexible w/a variety of selectable spkr-output-levels and one pure 
2) my rivera m100 has a built-in switchable dummy-load, which does the job 
well so long as the line-out eventually ends in a suitable gtr spkr-cab, 
3) a switchable dummy-load w/compensated line-out made by mark bartel (of 
toneking amplifiers) that functions much like the rivera, but in a 
transportable box.

i don't know if this'll help ya, but over the years i've developed this 
system as my 'direct-recording' rig:
gtr>pedals>toneking comet 40 amp & cab>thd hotplate(set at -12dB, so 
still some gtr sound in the room)>ada ampulator (reactive power tube 
tone-shaping)>small mixer (loops, fx, etc)>ada microcab2 (speaker 

>2nd question - do you have success with taking the Line Out from a Rivera,
>running it through rack gear, and going out to other guitar amp(s)?  
that has worked for me, in the past, but:
i would think that jc120's are not gonna be the perfect match for what i 
presume is the KH's original tone.....
experimenting is the *only* way to find out what might work for ***you***!

>tone gonna sound like doo-doo?  I can't really test this until I have a
>dummy load.
as far as i can tell, the 2 major available choices would be:
1) the thd hotplate (which i quite like, myself), and
2) the palmer stuff..... ( available at http://www.palmerdirect.com/  )

hope that helps!, and sorry if it doesn't.....
