Additional Notes:

From Alex Anest:

You may want to adjust the input cap. My Rangemaster replica sounds totally different with my (single coil) Tele than it does with my home-made humbucking thinline Tele, and so I use a different "range" by flipping the input cap switch. A .033uF or .05uF seem to work well for single coils, between .005uF and .001uF for humbuckers.
