Description

here at Just Pedals we love this Radial Engineering Tonebone PZ Pre Acoustic Preamp & DI Pedal.

The Tonebone PZ-Pre Acoustic DI Box Preamp from Radial Engineering is equipped with piezo acoustic input signal boosters to allow both add-on instrument pickups and built-in, integral active preamps to be combined for a more natural rendering. It is compact yet full featured, designed for both studio and live performance.

The Tonebone PZ-Pre instrument preamp begins with two inputs for two instruments, which can be toggled using the toggle foot switch. If you want to use two pickups on a single guitar, a unique Mix function is provided that converts the two channels from “either-or” to both. There are separate level controls for each input.

The tone shaping on the PZ-Pre preamplifier is simple yet extremely musical. It features powerful bass and high controls with a semi-parametric mid. This is supported with a feedback eliminating notch filter with variable frequency sweep control and choice of normal and extra deep notch filtering. To help eliminate troublesome resonance, a dual slope low cut (high pass filter) is also provided. An internal polarity reverse can also be engaged to help eliminate run-away feedback.

To augment on-stage performance, the PZ-Pre Direct Box Preamp is equipped with a combination power booster and effects loop bus. This allows you to introduce an effect such as a chorus, or boost the signal for soloing with a simple foot stomp. A separate tuner out has also been provided along with a mute footswitch for on-the-fly tuning.

To facilitate all kinds of monitoring, the Radial PZ-Pre offers the most comprehensive output array ever: A standard instrument amp output sends the instrument signal to your personal amplifier. A pre-EQ balanced lo-Z balanced output is used to route the flat, pre-equalized signal the signal to the front of house mix position, while a second XLR out is post-EQ for on-stage monitoring and in-ear systems so that the musician can get the sound he wants. XLR outputs are equipped with polarity reverse and ground lift.

Like all Radial products, the PZ-Pre features heavy-duty 14-gauge construction and is supported with a 3-year transferable warranty. Comes equipped with an external 15VDC power supply.

Here’s what Radial say about the Radial Tonebone PZ-Pre Acoustic DI Box Preamp:

The Radial Tonebone PZ-Pre is the most powerful acoustic preamplifier ever to be put inside a pedal. And when we say acoustic, we do not just mean acoustic guitar; we mean ANY acoustic instrument including banjo, violin, cello, mandolin, contrabass, bouzouki or lute. The magic of the PZ-Pre lies in the combination of high performance 100% discrete class-A piezo boosters, an ultra-quiet preamp circuitry that will adapt to any pickup system and a host of connectivity options that put you in control of any situation.

The PZ-Pre features two inputs for quick instrument changes on stage, a powerful yet warm sounding semi-parametric EQ to tailor your sound, pl

Acoustic

Acoustic guitar effects are used to modify and enhance the natural sound of an acoustic guitar, offering a range of tonal possibilities beyond its traditional, unaltered sound.
These effects can be applied using pedals, multi-effects processors, or built-in effects units in amplifiers, allowing acoustic guitarists to explore a broader sonic palette and tailor their sound to fit different musical contexts

Preamp

A preamp, short for preamplifier, is an electronic device used to amplify weak signals from guitars, microphones, or other audio sources before they are sent to a power amplifier or recording device. Preamps serve several important functions in audio systems:

1. **Signal Boosting**: The primary function of a preamp is to increase the level of weak signals to line level, which is the standard level used in audio equipment. This boost ensures that the signal remains strong and clear throughout the audio chain, minimizing noise and distortion.

2. **Tone Shaping**: Many preamps feature tone controls such as EQ (equalization) knobs or switches, which allow users to adjust the frequency response of the signal. This can include boosting or cutting specific frequencies to tailor the tone to the desired sound.

3. **Impedance Matching**: Preamps often include input and output impedance controls to match the impedance of the source device (e.g., a guitar pickup) with the impedance of the connected equipment (e.g., an amplifier or mixer). Proper impedance matching ensures optimal signal transfer and prevents signal degradation.

4. **Coloration and Character**: Some preamps are designed to impart a specific sonic character or coloration to the signal, adding warmth, richness, or saturation. This can be achieved through the use of vacuum tubes, transformers, or other analog components known for their unique sonic characteristics.

5. **Gain Staging**: Preamps play a crucial role in gain staging, which involves managing the levels of audio signals at each stage of the signal chain to optimize signal-to-noise ratio and prevent distortion. By adjusting the gain or volume controls on the preamp, users can control the overall level of the signal before it reaches subsequent stages of processing or amplification.

6. **Phantom Power**: Many preamps provide phantom power, which is required to power condenser microphones and certain active DI (direct input) boxes. Phantom power is typically supplied at +48 volts and is transmitted through the microphone cable to power the microphone or DI box.

Preamps are commonly found in a variety of audio equipment, including guitar amplifiers, mixing consoles, recording interfaces, and standalone preamp units. They are essential for ensuring clean, clear, and balanced audio signals in both live sound reinforcement and studio recording applications. Additionally, dedicated guitar preamps are available as standalone units or built into amplifiers, offering guitarists additional control over their tone and signal chain.
