House of Vans joined forces with BOSS and Roland to bring to Waterloo Tunnels Cause & Effects, a ten-day celebration of four decades of guitar technology.

For this exclusive take-over, BOSS and Roland have assembled an unparalleled collection of guitar technology, workshops and artist appearances.

Visitors will encounter pristine tape echo units from the ’70s, first-issue pedals, rare guitar synthesisers from the 80’s, collectable memorabilia and insider stories, along with enough oddities and special editions to satisfy even the most diehard gear nerd.
