The Zero To Sixty Overdrive is a guitar overdrive pedal from McCaffrey Audio. The maker announced it as a new overdrive pedal, the Zero To Sixty Drive, placing it in the overdrive category rather than distortion1.
What it does
McCaffrey Audio describes the pedal as integrating "cool, classic, overdrive tones heard on countless recordings with many of the most requested after-market mod", meaning it aims at familiar classic overdrive sounds with popular modifications built in1.
Controls
The pedal's most distinctive feature is the Shift toggle, a three-way switch that selects between different clipping options, the part of the circuit that shapes how the signal breaks up2.
| Control | What it does |
|---|---|
| Drive | Sets the amount of gain while letting the guitar's original sound come through at any setting2 |
| Shift (left) | A mix of diodes in symmetrical clipping, giving a bit of a boost, a slight increase in volume and a tad less compression than the right position2 |
| Shift (right) | Stock symmetrical silicon clipping1 |
| Shift (middle) | Works well for pushing the front end of an amp or another pedal1 |
The left position's diode mix makes it usable as a light boost as well as an overdrive, while the middle position suits players who use the pedal to drive an amp or another gain stage rather than to supply all the dirt itself21.
What reviewers said
Mike B, reviewing the pedal for Pedal of the Day in May 2015, praised its two toggle switches, its mid-focused Tone control and its versatile clipping options, and summed up the Shift switch this way:
"The Shift toggle is pretty rad: it's a 3-way switch"
Of the Drive control, he noted that "this Drive is a little different, as it really lets" the guitar's original sound come through at any setting2.
