The BOSS AD-2 Acoustic Preamp is a stompbox for acoustic/electric guitars that's designed to make up for the often-lackluster quality of undersaddle, piezo pickups. The AD-2's Acoustic Resonance feature analyzes the input signal as you're playing and applies processing to recreate the woodier sound of your acoustic instrument. Twisting the knob associated with this effect adjusts multiple interlocking controls within the pedal itself, allowing you to tailor the resulting song for specific timbres or purposes—i.e., for fingerpicking or strumming—quickly and effectively.

Also on hand—or rather, under foot—is an ambiance effect which adds some reverb to the signal. This reverb is EQ'd and processed to work with your acoustic guitar in a more complementary way when compared to other, comparable reverbs. As with the ambiance control, one-knob adjustment of this reverb will affect many interlocking parameters.

The AD-2 offers one input for your acoustic guitar, though you do have your choice of two outputs. A standard output jack can feed an acoustic guitar amp or a monitor, while the DI jack’s TRS connection sends a balanced signal to a PA mixer. If you choose, you can turn off the ambiance effect on the DI'd channel, thus giving your FOH mixer the ability to apply reverb in accordance with their own predilections.

Should you encounter any feedback, a one-knob notch filter will help you mitigate it immediately. This pedal has a buffered bypass path, which helps bolster tone over longer cable runs. If you'd like to mute your signal while changing guitars or tuning with an external tuner, simply press and hold the footswitch for two seconds.

Q: 5. Are the input and output impedances in this description correct? They're backwards from other the other Bellari preamp, and mismatched for common turntable cartridges as far as I can tell, but exactly backwards so I bought something else. I wanted this one, but since the company did not respond to my question, I did not buy one. Maybe someone has one and can test it.

A: Yes. The listed input and impedances of: Input: 47 K ohm (high impedance) and Output: 32 ohms(low impedance) These are the correct specs and typical (though the output impedance is lower than most phono pre-amps.

Q: 6. Would like to know if I can connect the stereo output from the H9 to the Aux in on the Mixinglink to maintain a stereo effects signal? I will be using this with headphones. Or is there an alternative way to maintain a stereo effects path form the H9 with the Mixing link?

A: If you are referring to the Eventide H9 series of stomp boxes they all have two outputs for left and right. The Aux stereo input on the Eventide MixingLink is a stereo 3.5mm. So you will need this Y cable to maintain the stereo image you want to retain. I have attached the cable below.
