The hand-built and wired pedal is not true bypass, yet offers no colouration when being bypassed. The compression feature brings to the fore a slight amount of gain, depending on the setting. This is a subtle compression felt more in the fingers than it is heard.
When the switch is in the hard position the gain control has a decreased effect, but will add the most grit to your sound. The soft setting will give you slightly less, while the off position has the greatest boost response.
The tone on the Sex Drive really should be labeled as presence. This is not a traditional tone circuit adding or cutting treble. The tone control is very subtle adding clarity to your sound without altering your overall tone. This is a pedal that performs minute to changes for significant returns.
