Lag: This adjusts the delay between the original note played and the onset of the gate. You can use the lower half of the control to fine-tune your picking attack, and just past noon gives you slapback and reverse-esque sounds. Think of it as a pre-delay control for the gate.
Gate: Controls the sensitivity of the gate. Keep this low for the least amount of gating and longest reverb trails, turn up for running higher gain devices before or making the effect more subtle. When the Gate knob is all the way down, the gate is removed from the circuit. This can be manipulated with your guitar's volume control by lowering the signal level and forcing the gate to clamp shut.
Mix: Controls the balance between dry and wet signals. When set to its minimum, you will hear just the dry signal fed through the preamp. At maximum, the reverberated signal is the only thing present.
Verb: On a reverb pedal with no gate, this would control how long the reverb tail rings out. But since there’s a gate, this essentially governs the thickness of the reverb. Setting this knob low gives some mild reverberation and maxing it out gives a huge, harmonically rich reverb sound.
Pre: Controls the level of the onboard preamp.
The CBX accepts a center-negative DC power supply from 9 to 18 volts, capable of supplying at least 100mA of current (over is fine). Plugging in anything other than this (center-positive, AC, higher voltage, etc.) will potentially brick the CBX. I cannot recommend doing this. Check your supply and make 100 percent sure it says all the right stuff. If you plug in the wrong supply, you’ll immediately send your pedal to the shadow realm. Even though that sounds pretty cool, your CBX doesn’t want to go there, this I can promise. Run it at 18V for more headroom.
