From a held note to cross-string phrases: control the sound with your hands.
01Sustain
Sustain begins with a freely vibrating string inside the DriveChannel. The device rests on the two neighbouring support strings and keeps supplying drive while you hold it in position. Fret a note with the left hand, let it develop and listen to the steady part of the sound. This is the reference point for the other movements in this guide. A stable note makes it easier to hear what each new gesture changes.
Start away from the strongest pickup response if the sound is too loud or forceful. Move closer gradually and keep the string clear of the channel. The sustained tone does not require a loud amplifier feeding sound back through the room; the drive acts on the string. This is what makes controlled long notes possible at low listening levels. The official Sustain sample is a useful first comparison, but your pickup, fretted note and position will influence your own result.
Gliding
Gliding means moving along the strings while the guide grooves remain in place. With the neck pickup selected, approach it for a louder, brighter sound and retreat for a softer held tone. Keep the device pointing along the string direction throughout the movement. A diagonal twist can interrupt the response and turn an intended dynamic change into an alignment problem.
Try gliding on one note before adding a melody. Listen to the beginning, the approach and the return, rather than aiming only for the loudest moment. A small movement near the playing area can be musically different from a long journey across it. In harmonic mode, this same control produces the wah-like change described in the official guide. Gliding is therefore both a dynamic control and a way to shape colour; it does not need a separate pedal to make the gesture audible.
Bowing
For a violin-like stroke, coordinate each fretted note with an approach towards the pickup. The note grows as the device moves through the playing area. Retreat or reset the motion before the next stroke. The left hand chooses the pitch and timing, while the right hand shapes the onset instead of giving the string an ordinary pick attack.
Begin with slow notes of similar length. Keep their starting positions comparable so you can hear whether the motion is consistent. If every note reaches the loudest point too quickly, reduce the travel or begin farther from the HotSpot. If the phrase loses its definition, make the approach more deliberate rather than adding distortion immediately. The Violin sample demonstrates the family of articulation. It is a bowed character produced on guitar, not a claim that the device literally replaces a violin or reproduces every detail of its response.
HotSpot
The HotSpot is the strongest response near the selected magnetic pickup. Search for it with a slow approach from around two inches away, lowering guitar volume if needed. It is a physical location to recognise on your instrument, not a stored setting inside the device. A humbucker has two such areas with a weaker point between them, so its centre is not always the best place to begin.
Use the location differently for different techniques. Back away for mellow sustain, come closer for stronger articulation and work directly over it for cross-string bowing. This distinction helps keep techniques closer in level without changing the guitar volume for every phrase. Practise finding the area by sound, then repeating the approach. Learning where it is useful matters more than remaining at maximum output throughout a performance.
Pressing
Pressing increases the force on the support strings, bringing the DriveChannel closer to the driven string. The smaller gap increases drive and can help a note begin more quickly. Easing that pressure reduces drive. You can use a gentle press-and-release action for changes in articulation and tremolo-like movement, including the horn-style gestures described by the manufacturer.
There is an important limit: the driven string must still vibrate freely. If it touches the channel, the sound may buzz or stop. Return to lighter pressure rather than treating that contact as the normal operating position. Try the action on one middle string and separate it from gliding at first. Once you can hear the difference between stronger drive and approaching the pickup, combine them intentionally. Notes fretted high may need adjustment because fretting pulls the string farther from the channel.
Tilting
Tilting the body sideways decreases drive and can produce a cleaner, less distorted tone. The guide recommends it for convincing bow-like strokes, particularly on lower strings. Think of it as a controlled adjustment around the supported position rather than turning the device away from the string. You still need the drive field close enough and aligned enough to sustain the note.
The low E can require a tilt away from the string to prevent buzzing against the channel. Over the HotSpot, a tilted position combined with rhythmic pressing and releasing can create a pronounced tremolo. Establish the held tilt before adding that rhythm. Listen for a change in level and colour, and check that any roughness is intentional rather than accidental contact. The technique is especially useful when a fully level position drives the string more strongly than the musical phrase requires.
Rocking
Rocking changes which end is lifted. Raising the LED end slightly moves the drive field away from the string and pickup while the other end remains supported. The guide describes this as a way to soften a sustained sound near the HotSpot. Raising the switch end gives another reduction in gain; moving in and out of that position creates changes in tone.
Compare this with tilting: a sideways lean and an end-to-end rock are different movements, even though both can reduce drive. Try one at a time on a sustained note so that you can hear the result of each. Keep the remaining support stable and use small motions. Once the contrast is clear, you can combine a rock with a glide to create a phrase that changes both its drive and its relationship to the pickup.
Spiccato
Spiccato uses a light bouncing or tapping action onto the support strings for a percussive start. The guide compares it to the bouncing stroke of a violin bow. Work near the HotSpot and coordinate the bounce with the notes fretted by the left hand. A firmer fretboard tap can emphasise the attack. This gives a different onset from waiting for a quiet note to swell gradually.
Mute the support strings with the left hand where possible to reduce unwanted noise from the device meeting them. The action should remain controlled; it is not an instruction to strike the instrument forcefully. Begin with separated attacks on one note, then add a short sequence. Listen for the distinction between the intended percussive note and incidental string noise. The official Sound Clips page includes a Spiccato example for comparison, and the Player’s Guide shows how the motion can be combined with gliding and other controls.
String-to-string playing
Relax pressure slightly and move to the next string, letting the guide grooves settle into the new alignment. The guide suggests a steady wrist with arm movement to maintain the direction along the strings. You do not need to lift the device completely for every neighbouring-string change. Remaining close to the pickup helps keep a strong signal while limiting incidental crossing noise.
The strings will not all react equally. Lower strings can benefit from less pressure and a tilt, while higher strings may need more drive and a firmer left-hand start. Practise slowly between middle strings, then extend towards the outside E strings. The two outside positions have less neighbouring-string support, so they deserve separate attention. An even phrase comes from adapting the gesture to the string, not forcing exactly the same pressure everywhere.
Cross-string bowing
Cross-string bowing passes directly over the HotSpot so that each string sounds as the device moves across it. Unlike a sustained note, you do not wait for a separate swell on every string. Hold the wrist steady and move across in a straight path, keeping a slight, consistent pressure against the string plane. Keep the guide grooves aligned as they pass through successive positions.
These gestures are quieter than holding a sustained note over the strongest point. The guide therefore suggests returning volume and tone closer to normal picking settings if they were reduced for sustain practice. Make the adjustment gradually and listen to the balance. A lighter crossing gives a softer response; more pressure increases it. Lift away to stop the bowing gesture. Cross-string playing and sustained playing use different relationships to the HotSpot, which is why one fixed position does not suit every technique.
Arpeggios
Hold a chord shape with the left hand and pass across its strings over the HotSpot. The notes are sounded successively: this is an arpeggio, rather than the device sustaining every chord tone at once. Keep the path straight and the wrist stable, using arm movement as described for cross-string bowing. Do not pause on each string waiting for a long swell to develop.
Begin slowly enough to recognise the separate pitches. Check that the chord is fretted clearly before making the crossing gesture. Then adjust the speed while keeping the path and pressure consistent. If one string drops out, revisit alignment rather than increasing the whole phrase’s volume immediately. The official Arpeggios sample gives a listening reference. A repeated chord shape, a different order of crossing or a change of speed can alter the musical phrase without requiring another electronic effect.
Bending
Bending moves the driven string sideways, so it can leave the centre of the field. Above the twelfth fret, the official guide describes tilting and a little added pressure to keep it driven. Keep the appropriate guide groove on track as the string moves. The necessary adjustment depends on the bend direction and the supported position, so learn it slowly on a comfortable note.
First sustain the unbent note, then bend and listen for the point where the response changes. If it cuts out, return to the original pitch and check alignment. Do not press the channel into the string to force a result. The guide also describes moving farther from the pickup towards the bridge, where the string bends less, with some distortion to help maintain level. This is an alternative to explore after you understand the basic tracking movement.
Harmonics
Harmonic mode encourages upper harmonics and can make higher-register sustain easier. Standard mode can also produce harmonic colour, especially with notes fretted near the nut on the lower and middle strings. Moving towards the bridge away from the pickup can encourage upper harmonics, while bends and vibrato help them begin and give the sound expression.
For a more fundamental-focused tone, the guide suggests avoiding those low fretted positions or lightly damping the string behind the device near the bridge. Compare the two goals on the same note before combining them with a fast phrase. Harmonics depend on both the selected mode and how you play; they are not simply an on/off layer added after the guitar signal. The dedicated harmonic-mode lesson explores the switch, position and expressive controls in more detail.
Thumb grip and plucking
The thumb grip frees other fingers for plucking. The manufacturer describes holding the device with thumb and forefinger, placing the ring finger behind it and plucking the string in the DriveChannel. Start with the device slightly above the strings, then bring it close enough to sustain the note. This combines a familiar plucked onset with continued drive.
You can also sustain a low E or A while plucking higher strings, adjusting position and tilt to balance the levels. This differs from asking the device to drive a whole chord simultaneously. The guide presents other finger and pick grips as well; use its illustrations before experimenting with hand position. Learn one stable grip first, then add plucking when you can keep the driven string aligned. A new grip is worthwhile when it supports the phrase you want to play, rather than merely making the basic note harder to control.
