SonicWorld Telsie ST Bundle is a dual-plugin analog EQ package for BFD-style mixing and mastering workflows, combining the Telsie S and Telsie T 3-band equalizers. Modeled after rare 1970s German broadcast EQs (Siemens W295b and W695), it blends vintage tone shaping with modern enhancements like harmonic drive, crossover control, and linear phase processing. Designed for mix bus, mastering, and tonal shaping tasks, it functions as a character-driven analog EQ plugin bundle for DAW-based production.

Key Takeaway

The Telsie ST Bundle is less about precision EQ work and more about tone shaping through character. It fits workflows where broad, musical moves and harmonic coloration matter more than surgical corrections, especially on buses, stems, and full mixes.

Dual EQ architecture based on two distinct analog designs

The bundle includes two separate EQs—Telsie S and Telsie T—each modeled after different 1970s broadcast modules with their own tonal behavior.

Telsie S leans toward open highs and broad tonal shaping, while Telsie T focuses more on controlled low end and smoother presence. This gives two complementary approaches rather than redundant tools.

Switching between them changes how the same material responds, similar to choosing between different hardware EQ units in a studio.

3-band EQ design with broad, musical frequency shaping

Both plugins follow a simple 3-band structure—low, mid, and high—but with curves designed for wide, musical adjustments rather than narrow corrective moves.

Low and high bands use shelf-style behavior, while the mid band operates as a presence-focused peak filter with selectable frequencies. The curves are intentionally broad, meaning changes affect larger portions of the spectrum.

This makes them more suited to shaping overall tone than isolating problem frequencies. Subtle moves tend to have a noticeable impact on the mix balance.

Harmonic drive per band adding analog-style saturation

Each band includes a harmonic drive stage, allowing saturation to be applied independently across low, mid, and high frequencies.

This is not a separate effect—it’s integrated into the EQ process. Boosting a band can simultaneously introduce harmonic content, changing both tone and texture.

It becomes a way to add weight, presence, or brightness without relying on external saturation plugins. The result feels closer to analog signal paths where EQ and coloration happen together.

Crossover controls reshaping how EQ bands interact

Unlike fixed-band EQs, the Telsie plugins include crossover controls that define where each band begins and ends.

Adjusting these points changes how boosts and cuts spread across the spectrum. For example, pushing the crossover higher allows high-frequency boosts without affecting upper mids.

This adds a layer of control not typically found in vintage-style EQ emulations, making broad tonal shaping more precise without becoming surgical.

Linear phase and extended filter options for modern workflows

While based on analog designs, both plugins include features that go beyond the original hardware. Linear phase mode reduces phase issues in multi-track contexts, particularly useful on buses or parallel processing.

Additional peak filter options in low and high bands extend the available frequency choices, while low-cut and high-cut filters handle cleanup tasks.

These additions make the plugins usable in modern production without sacrificing their core analog character.

Vintage EQ tone focused on mix bus and mastering applications

The overall design favors bus and mastering use rather than individual track correction. Broad curves, harmonic interaction, and stereo shaping all point toward processing groups of sounds rather than isolated elements.

It can still be used on single tracks, but the strength shows when shaping the overall balance of drums, stems, or full mixes. The EQ moves feel more like tonal decisions than technical fixes.

Analog-style EQ workflow that prioritizes tone over precision

The Telsie ST Bundle centers around musical EQ decisions rather than detailed frequency correction. It requires a different mindset—working with broader moves and listening for tonal shifts instead of visual precision.

That approach can slow down corrective workflows but speeds up decisions when shaping overall mix character. For engineers who prefer analog-style processing inside a DAW, that trade-off is the main appeal.

FAQs

What is included in the Telsie ST Bundle?

It includes two EQ plugins: Telsie S (based on Siemens W295b) and Telsie T (based on W695). Each offers a different analog EQ character for tonal shaping and mixing.

Is the Telsie ST Bundle good for mastering?

Yes. Its broad curves, harmonic drive, and stereo shaping make it well-suited for mix bus and mastering tasks where tonal balance matters more than surgical adjustments.

How is it different from standard digital EQ plugins?

It focuses on analog-style behavior—broad curves, harmonic coloration, and interaction between bands—rather than precise frequency correction or visual editing.

Does it support all major DAWs?

Yes. It supports VST3, AU, and AAX formats on macOS and Windows, making it compatible with most professional DAWs.

Can it be used for surgical EQ tasks?

It’s not designed for that. While it includes extended controls, its strength lies in tonal shaping and musical adjustments rather than narrow, corrective EQ work.
