The 800 uses a Panasonic SU series Bipolar 'Lytic. The Digikey part
# is P1198 for 3.3M, P1196 for 1M and P1280 for 10M.
I would have the 1M in circuit at all times. With the toggle in
upper position a 3.3M would be in parallel with the 1M for 4.3M.
With the toggle in lower position a 10M would be in parallel with
the 1M for 11M. I might consider trying a 22M just to see what it
is like.
I have a Studio Electronics SE-1 which has a quicker attack than the
MOTM (I think - at least it sounds that way to me). I really like
the pop on the attack under some situations.
