3. engineering team to discuss our mic pre my first thought was to make a mic preamp that could offer several sonic characteristics in one box similar to having a rack of various mic pres Our first idea was to use one main mic pre circuit with filters and some various component and circuit manipulations to change the sound This worked Kind of Overall it still sounded like the same preamp with some filters IL didn t provide the real experience of having several preamp sounds in one box We went back to the drawing board and realized the thing we needed to do was to employ more than one unique preamp circuit in each channel This design concept led to two amazing preamp circuits called VINTAGE and MODERN VINTAGE is our take on the classic British Discrete Class A design It is thick rich warm and sounds great on just about everything MODERN is a new design based on ultra hi fi solid state components that provide a sound that is very precise clean and detailed The preamp adeptly catches the stick attack of a snare drum or the crispness of a vocal Now we had our two circuits excellent but could we expand on this concept Yes indeed We came up with a rather ingenious idea combining the VINTAGE and the MODERN circuits to create new sounds With that COMBO mode was born In COMBO mode the input of one of the preamp circuit is combined with the output of the other preamp circuit So VINTAGE COMBO means the input is the VINTA
