The MXR Ten Band EQ lets you tune your bass or guitar rig in seconds, and it's been upgraded with noise-reduction circuitry, true bypass switching, a lightweight aluminum housing, brighter LEDs, and a second output.
This pedal can be powered by the included ECB004 18-volt adapter or the DC Brick™, Iso-Brick™ and Mini Iso-Brick™ power supplies.
By using two isolated outlets the Series adapter Flex gives you the sum of voltages of the two outlets used. This adapter Flex cable should be used in combination with any of CIOKS standard Flex cables if you want to power an 18V, 24V or even a 40V pedal.
