UST not playing nice with humbuckers
I added a UST to a board with 2 existing humbuckers and the UST is coming out with a lot of treble and the humbuckers have flattened out. What do I need to put between the UST and the board to get it all to play nice? Thanks!

I need a little more detail on exactly how you wired this up.
Does the UST sound OK on its own? If the UST is active and buffered before mixing with the magnetic pickups, the problem might be as simple as phase reversal.

The best applications I've seen have sent the UST through its own chain and directly to the P.A. rather than through the electric guitar chain with the mag pickups. for example, Andy Powell of Wishbone Ash has had a UST on his custom flying V for years and runs two signal chains.

The humbuckers are now muffled in all positions and in position 1 the K&K knockoff is twangy and treble-heavy. I would say it sounds almost identical to the body sensor I was previously unsatisfied with. I have a Fishman Matrix running to another jack that sounds amazing, I was hoping to integrate the whole system with the K&K and ditch the Fishman for simplicity and ease of use. I'm not understanding why systems like the Fishman Powerbridge can integrate easily into 2 humbucker systems on electric guitars, but this is giving me so much trouble. |

Regardless, the JJB is not going to work in the place of the body sensor which is wired in series with the neck pickup and hum cancelling coil when selected. The JJB is a very high impedance with series capacitance and the magnetic pickups are relatively low impedance with series inductance. To mix them will require active electronics. Here is my reverse engineering of the T5z switching schematic. https://www.acousticguitarforum.com/...d.php?t=401790 Far center is the hum cancelling coil for the neck pup: Far left is the body sensor:

Another option would be putting the Powerchip between the Taylor switch and preamp board which would let the Taylor controls impact the JJB. This would require a bit more complex surgery and minor modification to the Powerchip to replace it's assumed direct connection to the output jack of the guitar (you would need to locate the Taylor switched 9v power and run that to the Powerchip as its power switch is in its output jack). You would still need to cut a hole to mount the Powerchip and have access to the piezo volume control. If you want to route the JJB to the Taylor preamp, which will likely work OK, a simple toggle switch to choose between the Taylor switch and the JJB unbuffered output would be easier. I suspect the volume match between the magnetics and the JJB will be reasonable but not identical. It won't be a switch you will want to toggle in the middle of a song.

Any input you can give on this one I very much appreciate. |

You will want to add a passive 500K volume (and tone?) control(s) for the Taylor magnetics and run that to the Powerchip. The Powerchip assumes separate magnetic and piezo inputs. You add piezo to the guitar output with the Powerchip volume control.
But you don't get your goal of a single switch going between all the magnetic options and the piezo. Possibly the T5z native magnetic "acoustic" selection might sound great with a little SBT added. You could use the piezo input only of the Powerchip and put your "one switch to rule them all" ahead of that, but the volume mismatch between the piezo and magnetic elements and the lack of ability to blend piezo and neck magnetic with a POT would be a deal breaker for me. And one more useful bit of info, the Taylor preamp, all piezo preamps except the Fishman Matrix (to my knowledge), are flat response. That makes all of this a bit more flexible and if you want to ditch the Taylor switch and add the JJB directly to that replacement, aside from the volume mismatch and no ability to blend magnetic and piezo, it will very likely work fine with the Taylor preamp. If you go to my duo website you will find my phone number and we could talk this out much more quickly.
