If you aren't going to give a guitar the option for awesome trem action (ideally non recessed) you better give it a TOM for aggressive rhythm action. You will often see owners of flatmount bridges, in an effort to fill the void left by the absence of a trem, throw around pretentious phrases like "Jazz Influenced", "Holdsworthian phrasing", "Outside playing", and "Perfect Attendance in Second Year Community College Music Theory Class". This is a thinly veiled effort to compensate for the fact that their ugly guitars can't flutter or divebomb.
Flatmount bridges are, however, useful in some limited capacities. After a long day of masturbating to Guthrie Govan videos and BKP pickup reviews the limp wristed angle at which flatmount bridges encourage picking was found to be less tiring by 95% of internet progressive metal guitarists.
The word "recessed" itself, is derived from the greek "Recessum", which was a pit in the ground located outside of Carthage in which men viewed as unfit to breed were thrown. Trade caravans would often circumnavigate the pit by many miles to avoid hearing the womanly wailing of those trapped within.
