Just got one as payment for a studio session.
It is about the same size as my recto cab but has 4 celestion G12-K100 speakers.
Miced it up for the first time using Cannibalbarnes brilliant machine head cover from the Sneap forum.
TS808>6505>cab>57&421 on different cones>API mic pres.
Initial impression is I love it.
Very different midrange than the recto or my 1960av.
Very clear and less scooped with less fizz.
I will have to spend more time with it but think I will be using this a lot.
I believe Jens Bogren uses one of these a lot, including on Ghost Reveries.
I will make impulses when I have time.
Here is the test.
Same song with 5153 50wt>Rectifier cab.
Really looking forward to opinions on this sound.
Apparently the cabs are the only decent thing to come from the Mode Four series, although I can't think I've used one!
