flat low z pickup
Posted: Tue May 19, 2015 12:57 am
I've build a prototype of a thin low impedance pickup.
Which is basically a regular pickup with only a few turns. The output is a lower then a regular pickup but when connected to a microphone input I get a very decent sound.
I used:
4x 25x5x3mm Neod. magnets
2x piece of 1.6mm cardboard
appr. AWG 44 / 0.05mm copper wire from a salvaged inductor
I've put two staples on the side of one piece of cardboard to use as soldering points. Then I glued the magnets on the first piece of cardboard. I let the magnets provide their own pressure by placing a metal piece under the cardboard. When the glue dried I glued on the second piece of cardboard.
I've wound 250 turns and got a dc resistance of 274 ohm.
I then soldered the ends of the wire and a microphone cable on the staples.
The height of the pickup is around 8mm, but could be made lower by using less (thicker) tape and smaller magnets.
The sound is very good and because of the balanced input their is hardly any noise / hum.
I'm planning to use a slightly thicker wire (0.1mm) and experiment with the number of turns, although I want to stay under the 300 ohms.
