8211; we performed the same clean mods on this amp that we did on the britain 30 which gives the amp more clean headroom via a reduction in preamp gain and a power supply modification. the newcastle mkii builds upon the newcastle 30 by adding the body control that we developed for the original mcfly! the body control is a 6-position rotary switch which allows the player to select various configurations of components to sculpt the amount of low-frequency in their tone. using a switch to control the frequency response provides an intuitive and repeatable method of dialing in your low-end and reduces loading on the guitars signal and results in a more natural and open tone like you'd find in a studio grade preamp. we&
