Introduction

Thank you for purchasing a Diamond Memory Lane 2! This pedal represents a major evolution

in analog delay. Building on the original Memory Lane, this new version offers the same high

quality analog sound with new features, improved performance and lower noise.

Each Memory Lane 2 uses two Panasonic/Matsushita MN3005 4096-stage bucket brigade

devices. These devices have been used in several well-known analog delays over the years, and

when coupled with an NE570 compandor

to reduce noise from the total 8192 sample and hold stages, produce a very warm echo signal.

The Diamond Memory Lane 2 is a sophisticated analog delay device with many interesting

features and capabilities. Please take a few minutes and read through this short user manual – at a

minimum skim ahead to the 'Operation' section for some important operational notes before

plugging everything in and getting started.

A few words about normal operation-

The ongoing appeal of bucket brigade delay devices can be partly attributed to their somewhat

lo-ﬁ sound quality. Two things in particular contribute to this as a result of using slow clock rates

to achieve longer delay times: high-frequency rolloff and noise in the delay path.

The high frequency rolloff is a combination of both the capacitive signal loss as the signal is

passed bucket-to-bucket, and the analog low-pass anti-aliasing and reconstruction ﬁlters required

to minimize aliasing (distortion artifacts) from the bucket brigades. Each element of the bucket

brigade contributes a small amount of noise to the delayed signal as it is passed on. With 8192

elements in our chain necessary to achieve the 1/2 second plus of delay, that results in a small

amount of noise at the output. The NE570 compandor does a lot to minimize the audibility of

that noise, but it can become more noticeable as the delay time is increased to its max. This

sometimes results in audible noise pumping after individual notes as the NE570 does its job.

Remember to protect your hearing and wear appropriate hearing protection when playing loud...
