The Billy Sheehan Signature Drive pedal is developed by EBS in close co-operation with Billy himself. It is based on the concept of mixing together a clean signal with a distorted to be able to preserve low frequencies and find balance between distortion and definition.
The option to add compression make possible to keep the note differentiation clearly audible even at heavily distorted sounds. There are three modes for the buil-in compressor, High, Mid and Off. For the Mid setting, there's an additional trim pot inside to set the level. There's also a trim pot to set the Threshold for the compressor.
The Billy Sheehan Signature Drive offers unlimited pre-post mix tone shaping, made possible by including a clean loop and a drive loop. It lets the user insert any other effect they wish within each loop to ’pimp’ the effect into your own signature effect! For example, connect an external EQ to the Drive Loop and shape the character of the distortion any way you want. Or, turn off the built-in compressor if you prefer to use a different type of compressor and put in the Clean Loop.
With the new extended size box from EBS, there are controls for Drive (gain for the overdrive engine), Tone (sets the frequency scoop for the drive), Level(sets level for drive channel post Drive Loop and pre final compressor) and Clean(sets level for the clean channel, post Clean Loop and pre final compressor).
