Hi,

i have just finnished a new bass guitar build with active electronics.

Everything works but i do get a loud gsm sound like in the good old days from time to time if my phone is in my pocket.

example of a gsm sound: (https://www.windytan.com/2013/01/the-gsm-buzz.html?m=1)

This kind of confuses me, because ive never had that happen with my other guitars and basses. 

I know the solution is simple with just not having a phone in my pocket but i still would like to know why this bass does it, and others dont.

specs of this Build:

- 2 Single Coil Pickups from a Fender Jazz Bass (I know, not optimal for noise reduction)

- preamp : https://artecsound.com/pickups/electronics/se3.html  (pretty cheap - could be the problem?)

- electronics cavity is shielded with conductive tape.

Also strange - this bass has no hum or other noise whatsoever, it will just start beeping when i recive a message on my phone.

Again, i know the easy fix is to put the phone away or in airplane mode but im still intrestet to hear your ideas.

Thanks 

Alex
