Thank you for viewing. This is a self-made aluminum machined case for effects pedals. Please consider the size to be equivalent to a Hammond 1590B. The fact that effects pedal cases affect the sound is something that various high-end effects pedals, such as the SHIGEMORI series, demonstrate. This allows you to house your own creations in a machined aluminum case. I purchased this new from Garrett Audio several years ago and have kept it in storage without ever using it. I believe it's quite rare, so please consider it.
