What We Think

This rare, early unit is in Used, Very Good Condition and has some minor wear to the paint / finish on the upper & lower edges, out by the corners. It was well touched-up by the prior owner and the front panel looks great! These are incredibly hard to find on the used market. It sounds incredible!

Manufacturer's Description from DW Fearn


This equalizer will change the way you think of eq. It's smooth and sweet, and can be very subtle at mild settings, but quite strong with aggressive use of the controls. Creative use of the low boost and cut will create a powerful bass that has to be heard to be believed. The high boost adds just the right brightness to vocals, guitars -- any sound, or even an entire mix. Even with extreme settings, the VT-4 will never sound harsh.

This single-channel equalizer uses passive LC circuitry with class-A triode vacuum tube stages for the input and output. The tube circuitry is largely derived from the VT-1/VT-2 mic preamp design, so the equalizer has much the same sonic character as the preamps.

The LC-style passive equalization circuitry is based on the classic designs that are still the best-sounding way to achieve high-quality tonal control.

The input is line-level, transformer balanced-bridging. An active vacuum tube input section has adjustable gain to accomodate input signals as low as -10 dBm. The input transformer is made by Jensen. The output stage utilizes the same custom Jensen transformer used on the VT-1/VT-2 mic preamps.

All controls are stepped for precise repeatability and uniform matching between units. High-quality rotary switches are used with 1% metal-film resistors. All of the audio capacitors are polystyrene or polypropylene. The inductors are custom-made for us by Jensen Transformers Inc.

The equalizer is constructed of heavy-guage aluminum, with a a 3RU (5.25 inch), 1/4-inch thick front panel, finished in D.W. Fearn red. It matches the VT-1/VT-2 series of mic preamps in appearance and construction.

Like the VT-1/VT-2 preamps, the Equalizer has been designed to provide an exceptional tool for audio professionals. The design frequencies and curves were determed by ear, after extensive listening to a variety of program material, both individual tracks and overall mixes. The result is a highly-musical equalizer with plenty of range for enhancing any track or mix.
