Landau used to answer some questions now and then over at his old MySpace page. I can only find one post on HRI containing that information, and although it may be partial, here it is below.

Here is some stuff straight from the Bison Burger King himself:

Yea, their in the right order now (the pedals)…
I use the “tape echo” setting in the MPX-1 a lot,
also the MPX-1 does delay & verb at the same time, good
for an effects loop box…
See ya around.

The compressor is first, then the Custom Audio Super Tremolo,
then the Tri Stereo Chorus which is the stereo split.
The rest are in the CAE mixers with the PCM-42’s at the end on left & right.
All the best.

RE: PCM70
I use it all time in the studio.
99.9% of the time its on the “pan delay” patch.
Its been set there for the last 15 years!
I use it for for a quarted note setting to match the tempo of the tune.
I usually set both sides for a quarter note with one side
4 to 8ms longer to spread it out a little.
I dont do the “eight note-quarter note” panning thing that much anymore…
I set the “defusion” to 25%.
When I use “Circular delay” setting I leave it on random tempo.

I usually set my MPX-1 to a .8th note delay with the PCM-70

I’m glad we had this talk…

Viva la gear Homos!

I was using Mesa Boogie heads with 1×12
cabinets and EV speakers on Street Talk.

The chorus sound was that blue 3 space Lexicon delay…
(I forgot the model, “Super Prime Time”?).
I use to slightly modulate just one side (pitch bend only, no original signal).
The other side was straight.
I was trying to emulate my old Boss Chorus CE-1…
Bob Bradshaw used to laugh and call it the “$1,600.00 Boss Chorus”

I sometimes use a Boss compressor (blue one) on clean sounds.
I rarely use it on dirty sounds.

I use the “Guitar Solo” patch on the MPX-1 a lot…
