Re: Mooer Acoustikar??
I used to have a Boss AC-2; the controls of the Mooer are identical, & the sound is similar. The way it works:
Body - shelved bass, like any 3-band EQ
Top - upper midrange & treble shape/contour
Most of the midrange is permanently scooped out, as you can hear in the video, and there's a treble blast.
I prefer to get acoustic sim sounds from an equalizer. The reason is that these acoustic sim processors imitate the sound of amplified acoustic guitars- a sound I don't find to be appealing at all; it's way different from the sound & feel of an unplugged acoustic guitar in my hands. With an EQ, I can more accurately balance the bass & midrange to get some of the dynamics back. As you can hear in the video you provided, a lot of the playing dynamics are lost due to filtering out so much midrange.
If you like the tone in the video, the Mooer would be a cool novelty pedal at a good price. Otherwise, start by seeing if you can squeeze an acoustic tone from your amp & electric guitar, just using the built-in tone stack.
