Just in case people miss it, the boss 3 for the price of 2 pedal offer is on again. I believe it is on via Andertons, Dawsons and PMT, here is the link to Andertons. Wish the offer had been on when I bought my loop station! It certainly is a great offer for anyone looking to build a pedalboard from scratch, or looking to add to their collection.
The offer ends on November 16th.
