Seymour Duncan HyperSwitch Bluetooth 5-way Switch

Super easy to install, no soldering required. Works great. May need to pick up a few of these for other guitars.

This gives you a lot of options for pickup selection and combinations and the app works well. The only caveat is that you have to have enough room in the control cavity for the size of the switch AND the 9V battery (if you don't have a battery box already in your guitar. I can get the switch in there, but there is absolutely no room for the battery. Had to run the battery wire to the outside and use some double stick tape to mount the battery on the back of the guitar. Not ideal but it does make it easier to switch out the battery when it dies.

I've always liked using atypical 5-way switching schemes, so this thing is a no-brainer. I don't love having a 9v battery in my guitar that will need to be changed eventually, but it's well worth it for the flexibility. My one and only gripe is that you can't do series/parallel on a humbucker. Are you listening, Seymour? That would be an amazing addition to an already awesome feature set.

Love this because it was simple to install. It SOUNDS better perhaps because it’s an active switch. No grounding issues whatsoever. Love the different combinations, so I can change the wiring, and phase with my phone! No need to spend money on a tech to wire it up, only to change my mind later. Plus I only need to turn on its Bluetooth if I’m experimenting with settings. Otherwise, it’s set it and forget it.Love it. Most definitely will pick up another for my other Strat.
