Warm Audio EQP-WA Tube EQ (REVIVE AUDIO MOD) PAIR - 2015 - Present - Blue

Warm's version of a Pulteq EQP1A which was modified for enhancements by Revive Audio.
The tubes have been upgraded to Genalex Gold Lion and one of the units has a rear-mounted level matching pot.

I'm downsizing my studio, but these were used lovingly (but sporadically) for a year or so.

They are in perfect condition and sound great.

**I will not be available to ship in August**

WARM says:

The EQP-WA faithfully recreates the most renowned tube equalizer in recording history, the original vintage Pultec-Style “EQP-1A.”Just like the original, the all-analog EQP-WA is able to maintain full, harmonically rich tone while adding and subtracting frequency information, compared to plug-ins and digital emulations that are unable to preserve the full character while sculpting the tone. The 100% analog, fully-discrete circuit adds anything from thump to punch to brilliance on the way in or in post-processing to program material. The original has been used on legendary recordings by artists like Led Zeppelin, John Mayer, Bob Dylan, The Beatles and more. Producers from Geroge Martin to Rick Rubin have used vintage originals to shape the sound of music’s biggest hits for decades.
Equalization is a key element of any professional recording, and the EQP-1A-style of EQ is the industry benchmark for professional EQ without compromising tone. To combat the expected tone loss during signal processing, the EQP-WA is designed just like the original with discrete tubes and transformers designed to enhance tone, not destroy it. Loaded with premium 12AX7 & 12AU7 tubes and CineMag transformers, the output amplifier section of the EQP-WA passes the EQ-corrected audio through tubes and transformers to maintain signal integrity and rich tone. This results in more width, depth, and separation on tracks. Favorite uses for the EQP-WA include setting vocals in a mix, adding final-touches to drums and final mixes, separating guitar tracks, and dialing in clarity to bass guitar. Even with that exhaustive list, there’s no studio application that the EQP-WA can’t handle

REVIVE says:

The EQP-Wa utilizes Cinemag input and output transformers which sound very smooth and warm in the circuit but the rest of the audio path leaves something to be desired.

The circuit is fairly close to the original but as with most Chinese manufactured units, the quality of the components leaves the sound in the Wanting category.  

One short cut beyond the quality of components is the lack of an interstage transformer.

The interstage transformer while not necessary for the gain of the design, did impart a fair amount of color and offered nice de-coupling for DC between the EQ and amp stage.  

Our modifications bring back the low end, smooth out the equalizer and bring back the character to the design.

The Results:

The service increases the headroom of the unit, widens the frequency response, smoothes out the response in a more musical way and increases the character/color of the design.

So The modifications:

We do a complete audio path upgrade using premium parts for lower noise and higher headroom as well as lower distortion.

All Audio caps are swapped out for better performance using Panasonic Parts and Wima Capacitors in the audio path for more authenticity.

This includes all filters as well and really is the Bees-Knees.

Bypassing is performed where necessary for lower noise in the power supply.

Power supply modifications are also performed Thru out for the lowest possible noise figures in the overall design and better current delivery.

Tubes are then swapped for more complimentary versions in the design in terms of authenticity.
