Been using the equipment stated in my subject line for 2 years now with my Taylor 814ce (with 2 AA batteries) and a Taylor 310 (with 9 volt) all prior to the ES-2 system. The sound has always been amazing, and have had numerous people express this. Just purchased a new Taylor Koa K-24ce w/v-bracing and the other guitarist purchased a Taylor 324ce w/v-bracing both with the ES-2 expression system...volume is decreased by 50% and when I turn up the volume on the Bose system-horrible feedback. I can't control anything and can't use these 2 new guitars....what am I doing wrong? Very depressing with all this top notch equipment...please help.

Hi Taylorman,

Please describe the feedback (low-pitched howl, high pitched screetch, resonance with a specific string). 

Is the feedback the same for both guitars?

What ToneMatch Preset are you using?

How far are the guitars from the L1?





Thanks for the reply…it’s a high pitched screech, even without hitting the strings…both guitars. The tonematch setting for my Koa K-24ce & the 324ce are both set to Taylor Grand Auditorium-strum. At this time the L1s is approx. 5 feet away and the B-2 another 2 feet further. I realize it would be more beneficial to distance myself a little more, however it’s in a basement with limited room and 7 foot ceiling. I haven’t had a chance to gig with it yet for fear of bad sound. The guitars mentioned previously in my first post never had an issue with feedback in the basement and were 50% louder to boot. Thanks for any help you can offer.



Hi Mike,

That doesn't sound like feedback. Here's something I found on the Taylor site.  The Taylor Expression System 2


The ES2 is designed to be plugged-in using a standard quarter-inch guitar cable, which will work in every circumstance: with an acoustic guitar amplifier, a standard direct box, or any other guitar-ready application.

Note: The ES2 is designed with different circuitry than previous versions of the Expression System and will not work with a balanced TRS jack. You’ll want to plug into a DI (Direct Input) box to convert to a balanced signal for long runs to a mixer or snake.

The T1 inputs 4/5 are balanced TRS (Tip-Ring-Sleeve).

Have you tried inputs 1, 2, or 3?


The direct box did help, as did the standard guitar cord. However, the volume is only about 50% as compared to other Taylor Expression Systems. The ES-2 just doesn't compete with the other guitars. Is there any settings on the T-1 that would help cut through at a better volume?

The direct box definitely helped as far as feedback issues were concerned as did a standard guitar jack, however the volume is only about half as loud as all other guitars with various stages of Taylor Expression Systems. Is there anything I can do on the T1 to help keep up with the other guitars?
