Helios 0011 Type 69 Vintage Originals 3 Band Mic Pre/EQ rack of 8.
Olympic Type 69 Series EQ as used by the Beatles, Rolling Stones, Bob Marley, Led Zeppelin, Hendrix, Bowie.
The EQ imparts colorful tonality, and is anything but neutral. Yet it can be pushed to its most extreme boost settings while retaining openness and clarity. The treble band is a beautiful sounding fixed 10kHz shelf EQ as it steps through its ten gain positions. The bass band functions as either a 50Hz shelf filter with selectable cuts (-3,-6,-9,-12,-15 dB), or a four-frequency selectable (60, 100, 200, 300) peak EQ. The bass peak EQ is odd in that even when the gain control is set at 0 dB, there is still a dramatic boost in band signal (roughly 2 dB!). The mid band operates as a frequency selectable peak (PK) or trough (TR) EQ. This mid band is unique in functionality because the peak/trough is assignable with the flip of a switch. This makes it handy for finding and setting notch cuts—turn up the gain pot and set the switch to “peak” to find the offending frequency—then simply switch to “trough” to cut. The mid band has eight stepped frequencies to choose from (700 Hz, 1, 1.4, 2, 2.8, 3.5, 4.5, 6 kHz)*. (Courtesy of Nick at Pachyderm Recording Studios)
“WON’T GET FOOLED AGAIN was recorded on the Stones mobile using 69s. These modules are the ones that re-create the sound I remember. On acoustic guitar a little 10k and 2.4, and a slight bass cut with a Neumann U87 and there is Glyn Johns 1970. Straight out of the box. It’s spooky.”
