power supply for guitar effect pedals MXR M238 ISO-BRICK, intended for reliable power supply of a large number of analog and digital effect pedals within the guitar pedalboard system. The MXR ISO-BRICK is equipped with 10 fully isolated outputs, which significantly reduces the possibility of unwanted noise, buzzing and interference that can occur when using multiple effect pedals at the same time. Thanks to the different output voltages and amperages, it allows powering a wide range of guitar and bass effect pedals. The device has six 9 V outputs, two 18 V outputs and two separate outputs with an adjustable voltage from 6 to 15 V. The adjustable outputs also enable the simulation of the voltage drop of a dead battery, which is especially useful for certain vintage effect pedals. The robust metal case with compact dimensions ensures durability and easy installation in the pedalboard, while individual LED indicators allow for power monitoring. The device comes with a Dunlop power adapter 18 V / 2 A (36 W), with a European mains connection. The adapter is of the appropriate specifications for the MXR M238 ISO-BRICK.
