Controls

DELAY

This controls the delay time of Delay1, from approximately 40 ms fully counterclockwise to 550 ms

clockwise. This control is inactive when selecting Delay2. Delay time for Delay2 is set using the tap

footswitch.

The EQ control is placed before the bucket brigade delay devices, and affects all echoes on both DLY1

and DLY2 but NOT the direct signal. The EQ in the Memory Lane 2 is not a typical boost/cut treble

control. Instead, a 'tilt' style EQ is used, first introduced in the 1970's by hi-fi manufacturer Quad, and

also used in the Diamond Compressor, Diamond Boost-EQ and the original Memory Lane. The goal of

this EQ is to provide subtle spectral shifts in the overall frequency balance of the delayed signal, not just a

simple dulling or brightening of the treble frequencies. In practice, the Tilt control provides a simple,

intuitive tone shaping tool. You can think of the EQ as a spectral 'see-saw' with the balance point fixed at

a mid range frequency. With the EQ in the center detent position, the EQ is completely flat. Setting the

EQ counterclockwise gives progressively darker repeats, while setting the EQ clockwise gives

progressively brighter repeats.

LEVEL

This controls the amount of delayed signal fed back into the input of the delay circuit for both DLY1 and

DLY2, which in practice controls the number of repeats that are heard. Note that this control can be

overridden for DLY1 using the 'Slap' switch (see details under Slap Mode in this manual).

Set fully counterclockwise, no signal is fed back, so only one echo is heard. At about the mid-point,

multiple repeats can be heard depending on the strength of the original signal. Past mid-point, there

starts to be sufficient gain for oscillation to begin. The onset of oscillation is also dependent on the delay

time (shorter delay times make it easier to begin oscillation) and the EQ (gain in the EQ, particularly

when set towards the treble side, can make it easier to begin oscillation), so some adjustment of the

Feedback level may be required if the delay time or EQ is changed. Note that in comparison to the

original, the Memory Lane 2 requires relatively higher Feedback settings to achieve oscillation.

However, we have included an internal switch to activate 'spaceship mode' (see details under Spaceship

Mode in this manual) which provides higher gain in the feedback circuit resulting in increased sensitivity.

SPEED

This controls the speed of modulation of the delayed signal, from about 0.1 Hz fully counterclockwise to

10 Hz fully clockwise.

DEPTH

This controls the amount of modulation to be applied to the delayed signal (does not affect the direct

signal). Fully counterclockwise, modulation is off - there is a clickable switch in the control that indicates

fully off. This rotary switch in the modulation depth control is a master on/off control for modulation for

both DLY1 and DLY2. When using DLY1, the MOD/TAP footswitch control allows for turning on and

off the modulation 'on the fly'. For DLY2, modulation is on by default unless the depth control is fully

counter clockwise. Also, note that the actual depth of modulation is affected by delay time – for a given

modulation depth setting, longer delays will give deeper modulation than shorter delays.
