ProTone® Heading



ProTone is a digitally controlled, fully analog pickup control system that allows continuous adjustment of coil and pickup interaction. It expands the usable tonal range of passive pickups without using digital signal processing or altering the analog signal path.

Most will—but not necessarily all.

ProTone exposes a much larger tonal range than traditional systems, including transitional regions between familiar sounds. Some pickups may have areas that are less musically useful, especially if they were not designed for continuous operation.
The system can be configured to emphasize the most useful tonal regions.

The signal path is 100% analog.
Digital control is used only to precisely adjust analog components—no audio signal is digitized or processed.

No.
ProTone preserves the inherent tonal character of your pickups. It does not model, simulate, or replace their sound—it simply allows greater control over how that sound is expressed.

ProTone® is our next-gen tonal platform that allows you to customize, order, and manage tonal products online. It works by letting you choose options, upload artwork, and submit orders directly from the portal.

Yes.
Your guitar’s identity, including pickup voicing and construction characteristics, remains intact. ProTone expands what you can access from it—it does not replace it.

No.
ProTone works with most passive pickups. However, ProCoil pickups are specifically designed for continuous control and provide a wider usable range and more consistent response.

Standard pickups are designed for a few fixed configurations.
ProCoil pickups are designed for continuous control across the entire range, resulting in smoother transitions and fewer unusable tonal regions.

ProTone expands access to the pickup’s behavior, but it does not change the underlying design of the pickup itself.

Higher-quality pickups typically provide:

* wider usable tonal range
* smoother transitions between positions
* more consistent response across the control range

Lower-cost, mass-produced pickups may still work, but can result in:

* unsable areas may be narrower
* transitions may be less uniform
* some regions may be less musically useful

In practical use, ProTone can often reveal strong tonal characteristics in pickups that previously seemed limited, while still allowing higher-end pickups to perform at a higher overall level.

In many cases, yes. Traditional wiring limits a pickup to a small number of fixed operating points. If a pickup does not sound good in those specific configurations, there is little that can be done without replacing it.

ProTone changes this by allowing continuous control over coil and pickup interaction. This exposes a much wider range of tonal behavior, including regions that are not accessible in traditional systems.

As a result, a pickup that may sound limited or unbalanced in standard wiring can often produce highly usable and even excellent tones within certain areas of the ProTone control range.

At the same time, overall performance is still influenced by the pickup’s design and construction. Higher-quality pickups will generally provide a broader and more consistent range, while lower-quality pickups may have narrower “sweet spots.”

Volume and tone control requirements are different from traditional wiring. Not in their standard form.

ProTone uses a different control architecture than traditional passive wiring. The volume control remains an analog control, but it uses a 50k audio taper potentiometer due to the buffered signal path, rather than the typical 250k or 500k values.

Tone control is not implemented as a traditional passive tone circuit. Instead, tone is controlled through the system using encoder-based control of digital potentiometers within the analog signal path.

This allows tone to be controlled with greater precision and consistency, while also enabling additional functionality such as preset recall or mode selection.

Because the signal is buffered.

In traditional passive systems, higher-value pots are used to minimize loading on the pickup. In the ProTone architecture, buffering isolates the pickup from the volume control, allowing a lower-value pot to be used without negatively affecting high-frequency response.

The result is:
more stable and predictable volume behavior reduced sensitivity to cable and load variation consistent tonal response across the control range

Yes.
ProTone is designed for both new builds and retrofits, depending on the configuration and available space.

Yes.
ProTone provides a stable and consistent output, which works well with both traditional amplifiers and modern modeling systems.

No.
The signal path is fully analog with no digital audio processing, so there is no latency. Properly designed systems maintain low noise performance comparable to or better than traditional wiring.

Yes.
The system operates on a low-voltage power supply, typically from an onboard battery or external source depending on configuration.

Yes.
The system is fully operable from the guitar itself using standard controls. External controllers and displays are optional and provide additional convenience.

Yes.
ProTone supports preset-based operation, allowing you to store and recall specific tonal states instantly.

In most cases, Yes.
Standard configurations are available for common layouts. For non-standard instruments, the modular system allows flexible installation.
