So before I order this little magic box I need to know something about it’s EQ. In the mobile App the EQ range seems to be between +/- 12dB while in their Chrome extension it’s +/- 24dB. For the project I plan on using this amp I will need more than 12dB so the question is, will I be able to use EQ presets with adjustments greater than +/- 12dB with the amp connected to my phone via Bluetooth? Or is the 24dB range only available when connected via USB to a PC? Thanks for taking the time to reply!
