That's a difficult pedal to get here in the US and who knows when they will build again. For subtle try the Palmer Bass Preamp. It doesn't have a IR cab simulation, only an analog circuit can emulation. The ShiftLine has really good IRs and their tube power amp modelling is also great. Have you tried playing with those
They are the only preamp manufacturer who has the most detailed EQ explanation. I used this guide for my other Fender ToneStack preamps (Demeter etc, Mesa 400) and it works.
Shift Line Olympic MkIIIS Tube Preamp: EQ Section
I have only seen one in person and was pretty impressed.
Maybe the grass won't be greener.
Source Audio EQ has surgical 10 band EQ (HPF) and clean boost. It is really good. Maybe the best compliment to the Olympic.
