Here's what EBS say
More gain. The Billy Sheehan Drive Deluxe offers significant more gain than the original purple version. A ‘Boost’ footswitch even push the gain on the Drive to the extreme when needed. The level of boost can be adjusted internally by a trim pot.
Phase inverter switch. With the ‘Phase’ switch set to ‘Inv’ (affects the drive only) you will achieve a more growly kind of distortion compared to the Normal setting.
Swappable op-amp. There are a lot of drive pedals that are considered to be ‘classics’. Many of them use some variation of a standard type of op-amp circuit design called an ‘8-pin dual inline op-amp’. The new EBS Billy Sheehan Signature Drive Deluxe offer the user the unique ability to change this ‘chip’ to one that offers different characteristics to the Drive effect. The chip is accessed easily by removing the bottom plate of the pedal. It’s attached to the board by an IC-standard socket, and does not require any soldering to be swapped. See the Demo & Samples Tab for a op-amp shootout video as a reference guide.
Shared features with 'the Purple' version
The super cool loops. Use the Clean Loop to send a clean signal to an octave pedal and obtain optimized tracking while the Drive channel is still in use. Or put an Equalizer in the Drive Loop to fine tune your distortion character. There are countless options to use these loops in creative ways; these are only two examples to get your mind spinning.
The built-in compressor. This pedal comes with a built-in compressor that you can leave off, set in Mid or in High position. The compressor helps to maintain definition of tone while you’re using heavy distortion. It also helps to blend together the distortion and clean tone better. There are two internal trim pots' that let you change the Threshold value and adjust the level of compression in the MID position.
The controls. DRIVE sets how hard the distortion ‘engine’ will work. TONE changes the character of the drive sound; LEVEL sets the level of the drive sound, and CLEAN sets the level of your clean tone.
