Nothing beats a solid outboard EQ. Something that can take an ordinary audio signal and effortlessly sculpt it in a way that infuses extra energy and life into it.

The Sebatron Spider EQ is such a device.

By using a twin-triode valve as the main gain element (12AT7 or 12AX7) the Spider EQ is able to twist and adjust the sonics of a signal either drastically or subtly. This is done using two elaborated Baxandall EQ stages in series and carefully wired through feedback loops that incorporate the valves. The discrete Class A circuitry and high voltage rails mean that all the goodness of the raw material is preserved and not overly coloured.

The Spider EQ features four bands of active equalization.

There are two outer shelving bands with two switchable frequencies each and two mid bands with four switchable frequencies each. Each band has up to 10db of boost or cut.

1. Low Shelf - 40hz, 80hz
2. Low Mid Band wide 'Q' - 160hz, 220hz, 360hz, 500hz
3. High Mid Band narrow 'Q' - 1.2khz, 2.2khz, 4khz, 5khz
4. High Shelf - 14khz, 8khz

The Sebatron Spider can handle a full range of signals and all the colouration is derived from the valves making the Spider's response tight and fast - particularly in the low register due to the direct coupled transformerless nature of the circuit.

Two healthy sized VU meters with backlit globes add the final touch allowing for easy signal level monitoring.
