The 1st version of the Memory Lane is definitely one of the most famous Diamond Pedals effects out there. That old Memory Lane was the first ever all analog delay pedal to offer tap tempo. It sounded immaculate, but like all analog delays, it did not offer long delay times (the maximum it delivered was 550 ms). That is what Diamond Pedals set to improve with the Memory Lane Jr delay. The MLNJr combines a digital sampling engine, with an all analog signal path before and after it. The result is a delay pedal with similar sound to the original one, but with and extended frequency range and over twice the delay time. The Diamond Pedals MLNJr Memory Lane Jr is by all means a fantastic delay pedal you ought to check out.
