This is a PULSE effector board. The approximate internal dimensions are 495x395x100mm. There are some scratches and dirt, but it doesn't seem to have been used much (as it wasn't taken out often). It's easy to handle because it opens and closes with four latches, allowing it to be removed vertically. I couldn't find the model number, but it's probably similar to the PULSE EC-05. Please check the size. Please refrain from price negotiations. Please consider it.
