From the vendor
Who doesn't enjoy a good little bit of kill switch action every now and then? The stuttering effect adds some great rhythmic and textural variety to a song, but the thing that has always bugged me about them is either a) I get slightly off tempo, b) I don't press quite hard enough and it doesn't kill, or c) my finger just gets really tired.
The Kill Box takes kill switching to the next level. Instead of having to repeatedly press the little button on your guitar with your finger, the Kill Box uses an MCU to execute a predetermined kill pattern. Want to change it up some? Don't worry, you can switch to manual or continuous modes.
The Kill Box has some great, innovative features, such as:
- Full analog signal path with no bypass switching
- Will pass signal through even if not powered on
- Tap Tempo
- 6 pattern presets
- Manual, continuous, or pattern-based modes
- Stereo or mono i
