NP feel free to PM me with any other questions, I ran the amp for a few months and took it apart and poked around in there and replaced some parts so I know a bit about it //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif.
He was asking whether it was a remote gain (like on the AQ amps) or a bass boost knob.
It's a bass boost knob //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif.
