Brand
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.

Expression pedals allow real-time control over specific parameters on compatible guitar pedals, such as volume, delay time, modulation depth, or filter sweep. Used with an expression input, they let players shape effects dynamically with their foot, adding movement and performance control that cannot be achieved with fixed knob settings.
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.
Your pedal is like a signature dish for your sound — a flavour-packed creation that transforms the bland ingredients of your guitar into something unforgettable. Each one adds its own seasoning, texture, and heat, turning a simple meal into a feast of tone.
These tasty little boxes sit in a row, like plates on a buffet, letting you mix and match flavours as you play. With one tap of your foot, you can swap sweet for spicy, subtle for smoky, and serve up something completely new. From the comfort food of warm overdrive to the fiery kick of fuzz, from smooth jazz sauce to heavy-metal spice, pedals give players a full menu of options to express their taste. And just like with food, once you’ve tried one dish, you’ll want to sample them all.
Collecting, trading, and discovering new flavours soon becomes part of the joy of being a tone-loving gourmet geek with a guitar.
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.
