I own a Taylor 214CEK DLX. The inbuilt Piezo pick-up system, ES2, sounds a bit thin. I wanted a simple solution to try and restore/add a little more body & warmth and restore the resonance without breaking the bank. I looked at many options that made similar claims but decided upon this one. I am running it along with the Zoom AC2 Acoustic Pedal into a Yamaha MG12XU mixer and I am getting a lovely warm tone using both pedals in tandem.
Of sturdy metal construction, this pedal is so simple to use. Just plug in the instrument, dial in your preferred tone and off you go! A single foot-switch engages the pedal or activates the bypass. It is True Bypass and also does not convert your signal to digital, so no latency issues with a dry signal. It also has inbuilt Feedback Suppression via phase reversal. This has to be set by unplugging, holding a button and plugging in power. I this mode the pedal is always activated and cannot be bypassed. Due to its compact design, it cannot house a battery and must be powered by the supplied PSU. There is also a USB port to enable firmware updates.
In summary, some may quibble about the price for such a simple uncomplicated pedal. That for me was the main selling point. The truth is most working acoustic players I know have a couple of go to sounds for their set and like it to be as easy as possible to achieve those sounds. I think this pedal delivers. I have not compared it practically with others so cannot give a direct comparison. I am sure there are better & more expensive ones out there but this suits my needs perfectly. I recommend it.
