Also, 1 delay will give you white, so maybe its just the middleground that
causes problems. Its possible that a linear waveguide based reverb will
shift the frequencies less.

You're right though, we should try an off the shelf reverb first.

As a first cut, have you tried valve_1209 + valve_rec_1405 + [some LP
filter] plugins? These make a fairly conventional tube model when applied
in that order, and the rectifier includes some line sag effects which are
the source of some of the compression effects (modulo my very basic
knowledge of electronics).
