Installing LR Baggs Anthem in Yamaha TransAcoustic Guitar

The TransAcoustic guitar is an instrument that uses a built in transducer and on-board processing to produce the same incredible sound found in a great sounding room without a need for external amps or effects.

Installing LR Baggs Anthem in Yamaha TransAcoustic Guitar

Unread post by GAViN617 » Wed Jun 06, 2018 8:33 pm

Hi everyone,

Found this forum on google and was wondering if any of you could maybe help. I've got an LS-TA that I'm thinking of installing an LR Baggs Anthem SL pickup system into. I love what the TransAcoustic can do acoustically but not really liking the sound when plugged in.

My idea is to isolate the actuator part of the system and upgrade the jack output to the Anthem, so I'll still have the acoustic effects, but it'll run on the Anthem when plugged into an amp.

I've taken some photos of the inside:

My initial thinking is to simply snip the required wires that output to the jack, thus allowing me to replace the jack with the Anthem system (to be done by a professional ofcourse), which will run on its own isolated power from a 9V battery. This will need figuring out which wires to snip.

Regarding the undersaddle pickup, since upgrading the saddle to camel bone - which has greatly improved acoustic tone - the sound from the actuator has increased in volume and feels like its clipping/zinging, even feeding back sometimes when played hard, when turned past 40% on either of the reverbs or chorus. I know the bone saddle is the cause of this since it isn't an issue with the stock saddle, but the tone improvement with it is substantial enough for me to want to keep it.

Since the undersaddle piezo from the Anthem is quite thin and flexible, I'm thinking it could be placed on top of the current piezo and double-act as a dampener, alleviating the issues I currently have with the TransAcoustic effects.

Let me know what you think! I'm no expert in guitar electronics, but it kinda makes sense in my head. Grateful for any input here!

Cheers,
Gavin

Excellent first post Gavin and a warm welcome to yamahamusicians.com and the string section :)

Is there no adjustment on the preamp board to take down the higher sensitivity now you have installed a bone saddle? Personally I hate that UREA material Yamaha keep using for the nut on nearly all their guitars so I would always replace it.

Yeah the step-up from the urea saddle to the bone was huge in every way! Yamaha should really consider making bone stock on their acoustics - they're doing themselves a disservice at the moment!

Looking through the soundhole I can't see any adjustment points of any kind on the preamp board, but I assume there must be some kind of adjustment possible, based on Yamaha's direct response to the feedback issue in this TransAcoustic owner's video.



In the meantime I'll just fit in the Anthem saddle and see if that helps at all. The guitar is still under warranty so I may give that a shot before I do anything that will void it.

I just posted on that video in response to Yamaha Music London asking people to send their guitars back for repair.

I would rather they told people what the actual problem is and let them decide if they want to fix it themselves...if that is indeed possible or send it back to the store.

Shouldn't be happening though. Yamaha are normally on point with quality control so I would imagine they will be all over this issue to make sure it doesn't keep happening.

Buongiorno a tutti.
Riporto la mia esperienza.
Sono possessore di una Yamaha LS TA da Ottobre 2017.
Anch'io avevo questo problema di feedbak ... soprattutto con la 5 corda (B in Italiano SI) ...
Non pensavo fosse un vero difetto ma pensavo fosse normale.

Ad Agosto 2018 ho voluto migliorare la sella del ponte e anche i pins.

Ordinai dal mio negoziante una sella originale per LS TA WT83730E BRIDGE SADDL WHITE 75X3X10 (per curiosità)
e una per LS 36 in osso QC780200 BRIDGE SADDLE BONE LL 75X3.5X10 in osso di alta qualità (per adattarla alla mia chitarra)

Ho eseguito l'adattamento della nuova saddle per LS36 da 3,5 mm a 3,0 mm e adattando l'altezza come quella già montata di fabbrica.

Con sorpresa il problema del feedbak è sparito...

Segnalo anche che la saddle originale in plastica montata nella mia yamaha ls è più bassa di quasi 1 mm rispetto al pezzo di ricambio e che la base non era perfettamente piana !!

Allego foto ed un video


Goodmorning everyone.
I report my experience.
I am a Yamaha LS TA owner since October 2017.
I too had this problem of feedbak ... especially with the 5 string (B in Italian SI) ...
I did not think it was a real flaw but I thought it was normal.

In August 2018 I wanted to improve the saddle of the bridge and also the pins.

I ordered from my merchant an original saddle for LS TA WT83730E BRIDGE SADDL WHITE 75X3X10 (for curiosity)
and one for LS 36 in bone QC780200 BRIDGE SADDLE BONE LL 75X3.5X10 in high quality bone (to adapt it to my guitar)

I performed the adaptation of the new saddle for LS36 from 3.5 mm to 3.0 mm and adapting the height as the one already mounted at the factory.

With surprise the problem of the feedbak is gone ...

I also point out that the original plastic saddle mounted in my yamaha ls is almost 1 mm lower than the spare part and that the base was not perfectly flat !!

I enclose a photo and a video
