Here is the first version, the second version could not be recorded. The second version has more presence. Thank you for watching!

I assembled a prototype to test and build on site.

You're right my friend. I studied the data in this thread and designed an equivalent circuit for the wal pickups. I corrected for deviations, and designed the amplifier's input stages so that the connected pickups were corrected for the frequencies of the original pickups.

Hi gues! Sorry for my English. I was very interested in the information from this thread, and I tried to make my own version of the wal amplifier. I had to change the input stages to be able to adjust the original frequencies of the pickup. I made a test recording yesterday on jazz bass P. S. : Don't judge my performance too harshly, I tried to record this quickly, I haven't played tool band covers before www.mp3
