“The GKL ma-peq is an outstanding piece of gear. Very detailed preamps and extremely useful and musical EQ section with a nice high boost switch. I’ve used it while tracking and mixing on many different sources including piano and vocals and it always improved whatever went through it!!”
— Pascal Shefteshy (Sarah McLachlan, Arcade Fire, Rufus Wainwright, Owen Pallett)
 
“The MA•PEQ Preamps and EQ’s sound amazing! Like really good, stunning.”
— Roel Verberk (Willie Nelson, Snoop Dogg, KANE, Live, Sandra van Nieuwland) with Maarten Harry de Boer

The Gaskell’s mic pres sound fantastic! I personally own two of their preamps and they are top-of-the-line gear. The Gaskell brothers are brilliant people with a passion for top-notch and innovative equipment.
