The Locomotive Audio Model 86B-2 is a dual-channel tube mic/Line preamp and instrument inspired by classic 1950’s American-style tube circuitry.

The Locomotive Audio Model 86B-2 offers a vast sonic palette for engineers and producers to explore, from bright vocals and well-defined acoustics to powerful drums and natural tube warmth.

An update to their original 286A, introduced in 2014 as a modernised version of the Ampex 601 "suitcase tape recorder”, the 86B-2 boasts a pentode EF86 and dual triode 12AY7 and super Premium MuMetal transformers. It also includes separate line and mic inputs and a much higher DI input impedance. 

The 86B-2 is designed to process audio with various tonal colourations. The two-knob system enables the engineer to fine-tune the type of character needed. Using this preamp, you can add tube-like warmth or drive it to create overdriven distortion, for example.

The 86B-2 is equipped with a 20dB pad, 100Hz high-pass filter, two mic input impedances, line-level mode and high impedance front panel DI on each channel.

As with other Locomotive Audio units, the 86B-2 comes with a lifetime warranty with parts and labour.
