So here are the Tom Anderson Options.
On the left we have the bridge options. The H1- through H3+ have ceramic magnets. The HO has an Alnico II magnet. The # denotes how hot it is with 1- the least and 3+ the most hot for TA pickups (there is no "4").
On the right are the neck options, a H1- and a PH1-. I do not know what magnets the PH pickups have, but they sound nice!
