The Serpent Audio Splice SA76 MKII Fet Compressor is a 500 series module that recreates the circuitry and sound of not one, but two classic FET compressors. The Splice-500 mode switching allows you to switch between the classic Blackface and vintage Bluestripe circuits at the push of a button.
 
In addition, the Splice-500 can also mix and match the two for entirely new sounds that can only be found with the Splice i.e. Blue Input Circuitry + Black Output Circuitry for Blueface mode or Black Input Circuitry + Blue Output Circuitry for Blackstripe mode.
 
Four Compressor circuits in one box
Input Circuit Black + Output Circuit Black = Classic Blackface Mode
Input Blue + Output Blue = Classic Bluestripe Mode
Input Blue + Output Black = Blueface Mode (Unique to the Splice)
Input Black + Output Blue = Blackstripe Mode (Unique to the Splice)
