Tech 21

Tech 21 is a well-respected company in the music industry, particularly known for its innovative guitar effects and amplification products. Founded in 1989 by musician and engineer Andrew Barta, Tech 21 gained prominence with its groundbreaking product, the SansAmp.

This analogue amp emulator was revolutionary because it allowed guitarists to achieve tube amplifier-like tones without using actual tube amplifiers. The SansAmp became a staple in studios and live performances, appreciated for its ability to provide versatile tones, from clean to high-gain, all in a portable, pedal-friendly format.

Over the years, Tech 21 has expanded its product line to include various other effects pedals, rack units, and amplifiers, maintaining a strong reputation for high-quality, analog-based products.

One of the key aspects of Tech 21’s success is its commitment to analogue technology, which many musicians prefer for its warmth and responsiveness. The company’s product line includes popular pedals such as the Fly Rig series, which combines multiple effects into a compact, travel-friendly unit, and the Bass Driver DI, a favourite among bassists for its ability to enhance tone and provide DI capabilities for live and studio applications.

Tech 21’s dedication to innovation and quality has made it a favourite among professional musicians across different genres, including notable artists like Geddy Lee of Rush, who has collaborated with the company to create signature models. With a focus on both practicality and exceptional sound quality, Tech 21 continues to be a leader in the world of guitar effects and amplification.

Filter

A filter pedal shapes your tone by emphasising or cutting specific frequencies, letting you sculpt everything from subtle tonal shifts to bold, sweeping textures. Unlike traditional wah or envelope effects, filters can be static or controlled in different ways, giving you focused control over how bright, dark, sharp, or resonant your sound becomes.

Use a filter to tighten the low end, tame harsh highs, or create synth-like sweeps and rhythmic movement. Whether you’re refining your core tone or pushing into experimental territory, a filter pedal gives you precise control over the flavour of your sound.

Wah

Wah refers to an expressive filter effect that sweeps through a range of frequencies, creating a vocal-like “wah” sound. Controlled in real time with a foot-operated treadle, it allows players to emphasise different parts of the frequency spectrum as they play. Wah pedals are commonly used for lead guitar, funk rhythm work, and expressive solos, responding closely to picking dynamics and foot movement.
