>> If one boost is going to drive the other, I'd probably have the rangemaster driving the MOSFET because it will probably have prettier clipping.
Thanks for the opinion. Sounds reasonable. Anyone else?
>> I'd personally give them each their own stomp switch: I like to be able to turn them on individually OR together, without having to twiddle with mini toggles. Those are easy to break with your feet if you're wearing shoes.
I envision one stomp and one toggle (though I'm mindful of your warning regarding the toggle). I see this pedal as always on under normal circumstances, but I want to be able to bypass it if I ever need to. Thus the 3PDT toggle, which is a whole lot smaller than a stomp (I'm trying to do this in a small enclosure) and can, I hope, be tucked away somewhere it won't be vulnerable, to be used rarely if ever. The stomp would switch the Rangemaster on; it would be wired either to put it in series with the MOSFET (probably before it, as you suggest) or to bypass the MOSFET when the Rangemaster is on. Your idea to be able to turn them on individually OR together has appeal, but I wonder if for my purposes it might be overkill. Although now that you've got me thinking about it, it does sound worthwhile.
Wait ... if you're wearing shoes? Who treads on their pedalboard in stocking feet? Is this some European thing?
Thanks,
Nathan
