Just for your info: the early Focus heads I think like the one above have 10 Meghom inputs the later models (like mine series 3) were less. When I sent it back to Rick he put a new impedance in there of 10 Meghom so that I could use a high imp pickup without a preamp. (I had been talking to him openly about why the Headway had a better eq section and he said looking at the specs of the headway the main difference was the input imp.) SO if you buy a focus you can always have RIck optimize it for your pickup.
