Heritage Audio Tubestrip Review: All-Tube Channel Strip with Preamp, EQ, Compression & De-esser (2026)

The audio world is abuzz with the launch of Heritage Audio's latest creation, the Tubestrip. This isn't just another channel strip; it's a testament to the company's commitment to pushing the boundaries of audio engineering. But what makes the Tubestrip truly remarkable is its ability to blend vintage warmth with modern innovation, creating a sound that is both timeless and cutting-edge. In my opinion, this is a game-changer for producers and engineers who crave the character of tube gear without compromising on versatility and control.

A Symphony of Tubes and Transformers

At the heart of the Tubestrip is its all-tube signal path, which is a nod to the golden age of audio. The use of NOS (New Old Stock) vintage tubes in the preamp and Vari-Mu stages gives the signal a rich, warm character that is hard to replicate with modern components. But Heritage Audio doesn't stop there. They've also incorporated four custom-wound transformers throughout the signal path, ensuring that the signal remains transformer-coupled from input to output. This attention to detail is what sets the Tubestrip apart from other channel strips on the market.

One of the most intriguing features of the Tubestrip is its morphing capabilities. The variable tonal character of the tube preamp can be adjusted to suit the source, whether it's a microphone, instrument, or line-level input. This level of flexibility is a game-changer for producers who want to capture the essence of different instruments and vocals. Personally, I think this is a brilliant innovation that sets the Tubestrip apart from other tube preamps.

A Characterful EQ and Compression

The Tubestrip's EQ section is a marvel in itself. Instead of using capacitors, the EQ relies on inductors for a characterful response that is typical of classic outboard designs. This gives the sound a musical quality that is hard to achieve with modern digital EQ plugins. The inductor-based EQ is a testament to Heritage Audio's commitment to preserving the essence of vintage audio gear.

The compression section is equally impressive. Based on the Lang P.LANE circuit, the Vari-Mu compression provides a program-dependent response that works well across a wide range of material. The single-knob 1B mode offers fixed, transparent compression for more controlled results. This level of versatility is a dream come true for producers who want to shape their sound without sacrificing clarity.

De-essing with a Twist

The de-esser is another standout feature of the Tubestrip. Instead of relying on a separate unit in the chain, the de-esser is integrated into the channel strip, handling sibilance with precision. This not only saves space but also ensures that the signal remains in the tube domain from input to output, preserving the warmth and character of the vintage tubes.

A Weighty Investment

The Tubestrip is a 3U rack unit that weighs in at 7.6 kg, which is a testament to its robust construction and high-quality components. The built-in universal power supply ensures that you don't need to worry about power issues, making it a hassle-free addition to your studio setup. In my opinion, the Tubestrip is a worthy investment for any producer or engineer who values the warmth and character of tube gear.

A New Standard for Channel Strips

In conclusion, the Tubestrip is a masterpiece of audio engineering that sets a new standard for channel strips. Its ability to blend vintage warmth with modern innovation, combined with its versatile features and robust construction, makes it a must-have for any serious producer or engineer. Personally, I think it's a game-changer for the industry, and I can't wait to see what Heritage Audio comes up with next.
