High-quality Burr-Brown Op-Amps and a straightforward yet versatile control panel deliver rich and dynamic tones with ample headroom and maximum tweakability.  From warm, vintage tones to modern low-end thump, ZIO is the first and final step in elevating your bass to its rightful place in the mix.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTotal Tone Control\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003eThe ZIO Analog Bass Preamp + DI features a perfectly executed and  intuitive set of tone controls to take your bass sound wherever it needs to go.  When used in tandem, the BASS and FOCUS knobs offer tremendous depth and power.  The BASS knob provides colossal low-end boost at around 100Hz, while also gently reducing muddy low-mids to retain clarity. The FOCUS knob sweeps the cut-off point of a high-pass filter to tame excessive sub bass and low bass frequencies, providing extra headroom for a concise and punchy sound.

Using high quality JFET Input Burr Brown OP Amps, this mode is transparent and will not add any harshness or excessive brightness. JFET mode is also very helpful in a studio or home recording environment for delivering a more natural sound to the DI or line inputs found on many pieces of studio equipment.

The LOW-CUT preamp has no impact on the low midrange or presence frequencies, and, instead, reduces the \"low lows\" to improve headroom and provide a tighter sound. This is especially useful on guitar neck pickups, some basses, synths, and any other sound that may be too \"boomy\" and overpowering in a live or studio mix.\u003c\/span\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp class=\"wsite-content-title\"\u003e\u003cspan\u003e\u003cmeta charset=\"utf-8\"\u003e \u003cstrong\u003eStudio\u003cbr\u003e\u003c\/strong\u003e\u003cmeta charset=\"utf-8\"\u003eSTUDIO mode is based on a pair of popular studio mixing tricks used on guitar and bass. It combines an EQ curve based on the famous \"Pultec Trick\" (used on records since the 1950s and still today) in combination with other tried and true methods to improve clarity. This mode provides a low mid cut to remove \"mud\" frequencies, a gentle presence boost in the upper midrange, and a natural-sounding high pass filter, to reduce low frequency rumble. With this mode, you can achieve a more \"polished\" sound that is intended to fit guitars and basses more clearly in a mix. Without all of that extra bass and mud, you also will gain more volume in the most useful frequencies. This mode works very well after fuzz and overdrive pedals for tone shaping as well!\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"wsite-content-title\"\u003e\u003cspan\u003e\u003cmeta charset=\"utf-8\"\u003e \u003cstrong\u003eE-Plex\u003cbr\u003e\u003c\/strong\u003e\u003cmeta charset=\"utf-8\"\u003eA recreation of the feel, character, and frequency response of a classic early 1970s tape echo unit, the E-PLEX mode offers a vintage-style FET buffer\/boost tone that is warm, clear, and a little bit dirty. Many players used to turn off the echo on these old units and simply use the dry preamp for its tone and feel as an always-on effect. In the original units, the output impedance was quite high, and this led to a high frequency roll off with long cable runs. This was difficult to control, but also part of the unit's top end character.\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0938\/1593\/0953\/files\/image_161_927ceeb6-8afc-4ed9-ba95-20c8ee1f1eb5.png?v=1756289495\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCable Length is Tone\u003c\/strong\u003e\u003cbr\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cspan\u003eWhen we connect a cable to the output of a passive guitar pickup, it does more than just pass signal on to the next device. Many guitarists will be familiar with the idea of different cables imparting a specific tonal quality. This is because cables have a property called capacitance, which increases with the length of the cable. This capacitance interacts with passive pickups and guitar wiring, to create a resonant filter and the higher the capacitance of the cable, the lower the cut-off of the resonant frequency. \u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eThe three toggle positions replicate different lengths of cable. Select the BRIGHT position to introduce a low capacitive load and the most treble content.
