The outer aisles are where you often seem to find the quirky, interesting and innovative items - and so it was with Hall 4.0, home of all things guitar.
We came across a table with some small Lego-related power supply units that mate together to provide a compact multi-voltage power option for pedalboards.
There's a range; each small module built to supply a specific voltage/current; bus powered and supplied from either a master module with AC mains input (outputting 18V at 2Amps), or by any power supply you happen to already have which provides between 12 and 18 Volts DC.
We asked Igor Gapchenko to give us the low-down.
