If there’s one style of preamp that professional engineers would unanimously agree has defined the tone of pop/rock records for decades, it would most definitely be the venerable '73-style of mic pre. '73-style preamps have been massively used in recording and live applications for many years and are still considered to be the “Holy Grail” of preamp choices today.  The Warm Audio “WA73 Family” consists of single and dual channel '73-style preamps (with & w/out EQ), that each pay careful homage to British audio history.


When we at Warm Audio decided to release the WA273-EQ it was imperative that it met vintage expectation in both design and performance.  The tone and sweet character that vintage '73-style mic preamps impart is so unique and familiar, that we had only the pure desire to release sonically accurate reproductions. After years of R&D, careful reverse-engineering, and countless hours of auditioning, the WA273-EQ has been born!


UK Blore Edwards Switch-Pots


A great sounding '73-style circuit should be just as reliable as it is great sounding. The complex dual concentric switch potentiometers in the EQ sections of the WA273-EQ are made in the UK by Blore Edwards who manufacture military spec switches and potentiometers.  The use of Blore-Edwards components is no small inclusion for a '73-style preamp-eq in this price range.
