Instead, I'll just use the jumpers as intended with the design, and since it will be a 4 channel preamp, I'll set channels 1-3 to 1 meg, and I'll set channel 4 to 10 meg in the off chance I will ever need it.
This will actually save cost (fewer parts), even though I've already bought the extra stuff. It will also make the panel layout simpler and less costly (fewer holes).
I'll be able to use the extra parts for other projects in the future, and this will just be less hassle.
