When you plug into ProTone®, the first thing you notice is what doesn't change—your pickup still sounds like your pickup. The character, the feel, the response… the passive DNA remains completely intact and unmodified. What changes is everything that used to get in the way.
Here's what that means in real use:
The core tone stays exactly where it should. ProTone doesn't overwrite your sound—it opens it up. You're hearing more of what was already there, not something new layered on top.
Instead of a sharp drop in output and body, you get a smooth transition from humbucker depth to single-coil clarity. The tone remains balanced, usable, and expressive across the entire range.
With a true linear blend, you can dial in precise amounts of each coil or pickup. Whether you want a touch of brightness, added warmth, or midrange focus, every position lands exactly where you expect—and sounds musical.
Traditional phase switching often sounds thin and unusable. ProTone transforms this into a gradual, controllable interaction—more vocal, more complex, and far more expressive.
Instead of jumping between neck and bridge, you can move fluidly between them—like a studio fader—finding tones that simply don't exist with a switch alone.
Depending on configuration, you have access to dozens—even hundreds—of distinct tonal positions at 10-bit blending resolution. Each one is a real analog state of your pickups, not a digital model or approximation.
No sudden volume drops, no harsh peaks, no settings that fall apart. Your tone stays balanced and predictable, so what you dial in is exactly what you get—every time.
What you hear is your pickup — but with its full analog potential finally unlocked.
The term "voicing" is widely used in the context of electric guitar pickups, yet it is often loosely defined and inconsistently understood. In passive systems, voicing is not a fixed attribute of a pickup alone, but the result of a coupled electromechanical and electrical system. This document defines voicing in technical terms, identifies the parameters that govern it, and clarifies how traditional architectures constrain access to the full voicing range of a pickup system.
In a passive electric guitar, voicing refers to the frequency-dependent amplitude and phase characteristics of the signal produced by the pickup system under load. It is the combined result of:
Voicing is therefore not a static property, but a system-level response function that varies with configuration and environment.
The pickup establishes the primary electrical framework that defines voicing. Key parameters include:
These parameters form an RLC network with a characteristic resonant peak, which is often perceived as the defining tonal signature of the pickup.
The pickup does not operate in isolation. The surrounding circuit significantly modifies its voicing through:
These elements alter:
As a result, the same pickup can exhibit different voicing depending on the circuit environment.
Traditional passive pickup systems define voicing through fixed electrical configurations and load-dependent behavior. These systems provide access to a limited number of tonal states, each determined by discrete wiring conditions and passive component interaction. ProTone® redefines voicing as a controllable system-level parameter by enabling continuous manipulation of coil and pickup interaction within a fully analog signal path. This document describes how ProTone expands, stabilizes, and normalizes voicing without altering the inherent characteristics of the pickup.
In the ProTone® platform, voicing is defined as the electrical response of the pickup system under controlled interaction conditions, including frequency response, amplitude, phase behavior, and harmonic content.
Traditional passive systems restrict voicing to a limited number of fixed configurations determined by wiring topology and load-dependent interaction. In contrast, ProTone treats voicing as a continuous, controllable variable derived from coil contribution, pickup interaction, and impedance conditions within the system.
This shifts voicing from a static attribute to a dynamic parameter that can be adjusted with precision and repeatability.
ProTone enables continuous control over both intra-pickup (coil-level) and inter-pickup (pickup-level) interaction.
Rather than treating coils and pickups as discrete on/off elements, the system allows gradual redistribution of their contribution. This results in continuous variation of effective inductance, resonant behavior, and phase interaction.
By accessing intermediate operating points, ProTone provides access to intermediate states across the entire interaction range. This expands the available voicing space beyond what is achievable through conventional wiring.
Voicing in passive systems is typically influenced by uncontrolled variables such as potentiometer loading, cable capacitance, and amplifier input impedance. ProTone stabilizes these variables through buffering and controlled impedance conditions, ensuring that changes in voicing are intentional and repeatable.
The system further incorporates calibration to measure the actual response of the instrument under operating conditions. This captures the combined effects of pickup characteristics, circuit interaction, and mechanical influences on string behavior, enabling consistent output and predictable voicing across presets and instruments.
Pickup design remains a defining factor in overall performance. While ProTone operates with standard passive pickups, the usable voicing range depends on their electrical characteristics. Pickups designed for discrete operation may exhibit uneven response in intermediate states, while ProCoil™ pickups are engineered for continuous interaction, providing smoother transitions and a broader usable range.
By enabling continuous control, ProTone expands voicing into a full interaction space rather than a set of discrete positions. This includes both highly musical regions and transitional states that may be less commonly used.
The control layer allows this space to be shaped, emphasizing the most useful tonal regions while retaining access to the full range when needed.
The practical outcome is a system in which:
ProTone does not create new tonal sources. It provides controlled access to the full range of behavior already present within the pickup system.
