How small can an entire live guitar rig get? Recently I built myself a super-compact pedalboard. It measures 10" x 8" and ready for a pedal-sized amplifier.
It measures 46cm x 27cm x 20cm (11" x 10.5" x 8"), contains two 8", high-power Celestion drivers, it can handle 300 watts and weighs just under 7.5kg (16.5lbs).
The layout is based on an in-line format like my former Pedaltrain Nano, but wider with space left in preparation for the addition of a board-mounted amp.
