Hi everybody. I needed a smaller box for our band V31, think Sunn O))) with vintage look and good pressure in the base registers for smaller gigs. I had an empty Marshall cabinet of unknown origin. Probably it has been a guitar cabinet as it is not as deep as regular Marshall bass cabinets. But I simply cut it down so that a Marshall 15 inch speaker element could fit. I think it was pretty successful LoFi look that fits well with my Marshall 1969 Super Bass.
