Actually I also thought about the battery thing... Maybe for other reasons than you, but I also somehow don't like it. Especially in the hollow body...would have to build a pocket inside, to put it in...little space and so on and so on... 🙂 For the explorer it was necessary, but here...no need for that...

I will check the options of different circuits...my problem is, that I don't know how all the different circuits sound like and how the things affect the sound and give varieties 🙂 I am definitely better in sanding and crafting than playing 😂 much much better...

What I am going to use are the mini humbuckers for this model...it is all about the optical thing...
Do I understand it right, that the two Höfner switches for bass/treble are like a 3way toggle switch? Then I would just use that one...
And rhythm/solo is just like a tone pot? Then I can keep it simple and have a nice visual solution in mind.

The two recommended wirings sound also interesting. Have to check the book 🙂
