Welcome. I wanted to provide stripboard layouts I've made to help people new to electronics and even the more experienced get into different aspects of electronics.

I verify the layouts before I post them.

Peizo Pickup Transducer Preamp Stripboard Veroboard Layout

this is actually from a request from a guy called Jim (sorry don't know your last name) who wanted a peizo preamp because they are so expensive. they are essentially just a high impedance preamp
and you could probably use this for other things like hiZ microphones and whatever.

there is a gain control on this and it uses an op-amp that is able to function as a single rail op-amp which cuts down the component count which is always useful when you need to hide this inside a guitar cavity or something.


  1. sounds real cool.one prob . gain pot has no effect. could you please help

  2. ok its all good now, thanks.

  3. Hi, I've got the same problem. could you please help.


  4. same here. i've build five of these, and the VR has no (audible effect). any ideas?!

    anyway, thanks for this layout.


  5. This circuit is wrong! Either the power should be symmetrical +9V GND -9V or first stage input (pin3) should be biased at 4.5V through a voltage divider (now is at 0V through R1)
