Hello TWIE,

I’m installing a Mag Mic on a current build and want get it close and test before sending it off to its new owner. 

How close do you set the poles to the strings? Do you have any tips/suggestions to set these up properly on a Weissenborn? 

If it requires shims, I’d like to make and install them before sending it off. I’ve been building for a bit now but am new to electronics and pickups. 

I hope all all is well and apologize for the short language... typing with my thumbs.

Thank you in advance!

_Mike

Hi Mike,

as a rule of thumb, between 2 and 5 mm.
You would want the body of the PU around 8 mm away from the strings. 
You can then adjust the poles heights to taste.

Now of course, this is a deep subject if one want to go far.

First, you want to shim any sound hole magnetic PU on a weiss because strings are much higher than on a guitar. Typically a 2/3 mm shim will do. Again it depends on the string height on that particular instrument. Cork, or soft wood is often use for the shims, no nasty chemical reaction to fear. I use leather myself, but I know where it comes from. The shims stick to the PU (not to the weiss). I use double sided tape.
Just use the pieces already on the PU as a template to make the shim.

The fine tuning is difficult. There are too much variables at play that you don't know, kind of strings, gauges, playing style...
Sound holes PU's are most often voiced for phosphor-bronze strings, on which only the core is magnetically responsive. But what if strings are nickel or steel based ?
It is well known also that if the poles are too close, the magnetic field induced force can have a bad effect on the sustain. In my experience, this is very true on electric guitars, less of an issue on weiss where gauges are heavier.
Let's just say that the closer the string from the pole, the punchier the sound, but less natural sounding.

Let the fine details to the end user.

(I work on that future weiss design we talked about lately. I don't know if we could call it a weiss anymore, at that point...)

Thank you so much for the reply and information!!! I’m going to shoot for 8 mm to the body of the pickup. 

Super helpful. Thank you!
