Ultra effective EQ:
Original 808’s tone knob is only effective mostly on the last 10% of the taper. The new tone knob mod splits bass and treble signal and lets you blend in desired amount precisely.
3 way “SHIFT” switch:
This is the best feature on the Sally Drive “Advanced”. The 3 way mid range toggle switch lets you select between stock 808 720Hz sweet spot, treble boost and low boost. Up = treble boost, centre = stock 720, down = low boost, very straight forward.
The treble boost helps you clean up unwanted bass and low mid which is perfect for driving tube amp OD. With gain lowered to half way you can play funky rhythm with absolutely no mud, even on a Les Paul.
Stock 720 gives you that SRV sweet singing mid that everyone loves. Basically it is the trademark tone of the classic 808
Low boost adds more bass and emphasizes the OD texture. Fat and tight, perfect for power chords and riffs on lower strings.
