- Controls the mix between the effect and the original signal. Count-clockwise gives you more of the original signal. Clockwise gives you more effect.
- Controls the range of movement of the envelopes sweep. Counter-clockwise sweeps more low frequencies. Clockwise sweeps more high frequencies.
- Adjusts the point where the effect's wah responds to your playing attack. With a higher sensitivity a smaller signal will affect the envelopes effect. In other words, with a higher sensitivity you don't have to pluck as hard to make the effect audible.
A famous user of the DOD FX25: Bootsy Collins!
The FX25B is the reincarnation of our original envelope filter. You still get that great automatic wah sound, but we've taken it one step further by adding a blend control making the FX25 equally responsive to both the guitar and bass guitar.
