Traverse Analogue

Traverse Analogue is a limited-run manufacturer of boutique professional audio equipment, intended for use by recording, mixing, and mastering engineers. Utilizing the finest discrete componentry available, their designs are precisely engineered for analogue warmth and low-noise characteristics.

There mission is to produce the finest sounding designs for the professional audio industry; engineered to interface with modern recording systems, and meticulously handcrafted into tjeir line of outboard instrumentation.

Traverse Analogue began in 2018 with 10 years of research and development behind it. Their discrete topologies include vacuum tubes, FETs, and BJTs in the audio path, combined with state-of-the-art power supplies and various types of discrete and integrated control circuitry.

They back their design confidence with unsurpassed customer service, direct technical support, and a 2 Year Limited Warranty on all products.


The 652

Vacuum Tube Preamplifier


Introducing the stereo vacuum tube preamplifier with mic/line-level inputs; the 652!

Using the GAIN control, the engineer can achieve 5 - 60 dB of gain from the uniquely-biased tube input stage, followed by a MASTER attenuation control in the output buffer stage. Want a clean yet musical replication of the source? How about the creamy saturation of an esoteric vintage preamplifier?

The 652's gentle drive characteristics allows for a broad tonal palette depending on how hard you hit it with signal. It is designed to interface with all types of microphones (including ribbons), and the line-level input pad allows you to add analogue warmth to any track from a digital audio workstation; making it an indispensable tool for adding colouration and harmonic distortion!

Two flavours, one box, all discrete, and proudly hand-crafted in Canada.

  • The Mass-DI

    Mass Direct Interface


    The active Mass-DI features discrete JFET/BJT circuitry with a custom designed “mu-metal wrapped” Lundahl transformer, giving the source a natural sound with a fast and punchy transient response. 

    Each unit is handcrafted with care using the highest quality components available. It’s designed for use with ¼” unbalanced instruments (including those with piezoelectric transducers) and line level sources, with a balanced XLR microphone level output. It can also be used between an amplifier and speaker to sample amp tone directly!

    Simple, elegant, responsive, and proudly hand-crafted in Canada.
