Help with electrickery for a newbie

Lee Parkes

Recommended Posts

Hi all -I'm new to this forum - used to follow another forum which has folded and only recently got back into building again...

I am building a EBMM  Luke 3 inspired guitar and am trying to replicate the electronics  - apparently the Luke 3 has passive pickups with an active preamp with a variable dB boost...I cant simply use their components as they are not available for sale. Can anyone help me with sourcing some  electronics that would achieve this  - (HH config with coil splitting as well if poss)- preferably off the peg.....

thanks in advance

I did this a while back thanks to help from @mistermikev which is close to what you're looking for (apart from position 4). Using a fender 5-way super blade switch, I think Oak Grigsby do one too. Note position 4 - I was clearly trying to write neck and treble in the same word :D it's Bridge single + neck single 


pic below taken from the music man website. I was using PRS pickups which only have 3 wires - live, ground and coil split. So I am unable to have 2 options for inner and outer coil settings like the MM positions 2-4. I think you would need 4 conductor pickups to make that happen. It's only my opinion, but I think you will get better variance of tone between positions 2 and 4 if you do the PRS bridge hum + neck single than the Music Man outer coils vs inner coils, it will give you a slightly higher output quack which is cool for bluegrassy stuff whereas the MM 2 and 4 will sound pretty similar. However an active EQ will give you a whole world of other possibilities anyway,


I did a passive bass with active EQ earlier this year, the active EQ just goes in the circuit between the output of the switch and the jack, and it is a lot more straight forward than I thought it would be. Just make sure you use a stereo jack and connect the battery earth to it so your EQ is only draining power while the jack lead is in.

Looking forward to seeing your build thread!

I've looked online and struggled to find any ut thanks anyway 

Google is your friend:

Seymour Duncan Do It All: 2 Humbuckers And A 5-Way Switch - Guitar Pickups,  Bass Pickups, Pedals

Your preamp would go inline between the middle lug of the volume pot and the tip connection on the output jack. As @ADFinlayson mentions, the output jack would need to be replaced with a stereo version to allow automatic disconnection of the battery when the lead is unplugged.
