The 6 Degrees FX Sally is a recreation of the early version of the Tube Screamer 808. This “Advanced,” 5th anniversary version features a three-way mid-range toggle switch that “lets you select between stock 808 720Hz sweet spot, treble boost and low boost.” Touch sensitivity is one of these pedals’ main strengths.

Here’s the Demo by Shnobel.

Extremely effective active treble and bass EQ gives you +/- 6dB to shape your ideal tone. Boost the low end for your Strat or cut the muddy low from the Les Paul, the flexibility is limitless when used in conjunction with the mid SHIFT switch.

3-way SHIFT mid range selector:

Choose from 808 stock 720hz mid boost or the added 590hz/480hz for more low mid to suit your guitar/rig combo. The increased low mid gives extra ballsiness to your tone but it will never become muddy thanks to the well-balanced EQ.

G.A.S. Switch

Custom voiced germanium, Asymmetrical and silicon clipping.
Silicon clipping sounds closest to the original 808 but has less compression, more open feel.
Germanium clipping has a warmer voice with very nice, even texture.
Asymmetrical clipping has the most gentle voice. Less fizzy top end and a fatter body with great clarity. Well suited for complex chording.
