Has anyone used a Bass EQ pedal for their Acoustic/ Electric?

[catgut]

On samash.com below their ad for the BOSS BASS EQ PEDAL IT SAYS:

 

"Since the frequency range extends down to the 50Hz range, the GEB-7 is also great for adding depth and bottom end to acoustic guitars"

 

3 QUESTIONS:

 

1. Has anyone tried this?

 

2. Has it worked better than a normal guitar eq pedal?

 

3. If you use this then what the hell would you need a preamp for?

 

(Since I'm kinda a newbie to amplified acoustics I'll appologize in advance.)

thanks for any responses! :)
