Basic Overdrive Operation
Overdrive is a type of effect that works by distorting the input signal. Distortion can occur in a variety of ways and results in a wide variety of outputs. This table shows a simple representation of what some different types of distortion look like.
Clean signal: With no distortion, the guitar signal passes through the circuit unaffected. In this example, a pure sine tone is used as a test signal.
Tube/transistor saturation (soft clipping): |
Asymmetrical: |
Tube and transistor amplifiers enter a |
|
saturation state when overdriven and start to |
|
distort the shape of the signal. This involves |
|
some soft clipping at the peaks and valleys of |
|
the signal, and may be symmetrical or |
|
asymmetrical in shape. |
Symmetrical: |
|
Diode clipping (hard clipping): Diodes can |
Symmetrical hard clipping: The signal clips |
clamp or limit the signal to a maximum level. |
equally on the top and bottom. |
Asymmetrical hard clipping: The signal clips at different levels on the top and bottom.
Overshoot: Depending on the characteristics of diodes and transistors in the circuit, the signal may exceed its normal clipping point before settling, which is known as overshoot.
SA244 |
L.A. Lady Overdrive User’s Guide |
8 |
Extreme overshoot: The overshoot phenomenon can be taken to its extreme for fuzz and metal sounds.
Octave: A rectifier can be used to double the frequency of the signal, creating an octave fuzz effect with a unique tonal character.
The various drive circuits in the L.A. Lady Overdrive utilize a combination of these different approaches to create tones inspired by the classics, as well as new groundbreaking tones that bring their own unique flavors.
Effect Types
The L.A. Lady includes three basic overdrive types, with more effects available in the Neuro mobile app.
Classic
The Classic circuit offers an overdriven amp distortion sound with a smooth texture. Good for adding a little extra grind for an “always on” tone.
Crunch
The Crunch circuit is our own version of an overdriven tube amp made more aggressive and out front.
Smooth
The Smooth circuit offers a heavily saturated tone reminiscent of Mesa-Boogie® amplifiers. This aggressive approach to overdrive with its boosted highs and lows generates the thick, focused and heavily sustaining tone that inspired countless artists from Carlos Santana to Metallica.
Additional Effect Types
Additional effect types can be loaded into the L.A. Lady using the Neuro App on your mobile device (iOS / Android) or the built-in USB port (Mac / Windows).
The L.A. Lady Overdrive is compatible with Source Audio’s Fuzz and Distortion effects, so it is possible to load Overdrive, Distortion, and Fuzz effects on the L.A. Lady at the same time.

Knobs
Drive Knob
The DRIVE KNOB adjusts the amount of gain applied to the signal. Dial down the drive for a cleaner, more articulate tone or crank it up for over-the-top doses of overdrive.
Level Knob
Adjusts the output level of the effect. This is useful for setting the level of the overdrive effect compared to the bypassed signal. Note that because the overdrive effect compresses the signal in the clipping/saturation stage, the dynamic range of the distorted signal will be less than the dry signal, and the LEVEL KNOB can be used to compensate for the loss of level that results from this compression.
Bass Knob
The BASS KNOB adjusts a low shelf tone control. Turning the knob clockwise will boost the bass; turning the knob counter-clockwise will cut the bass.

Preset Storage and Recall
The L.A. Lady features a user preset that can be easily saved and recalled using the footswitch. When a preset is recalled, all of the parameters instantly jump to their saved value, regardless of the position of the knobs. This allows you to save your favorite sound without having to worry about the knob positions.
Saving Your First Preset
Bypass the L.A. Lady by clicking the ON/OFF FOOTSWITCH once. The ENGAGE/BYPASS LED should be dark at this time.
Press and hold the ON/OFF FOOTSWITCH for 5 seconds and wait for the ENGAGE/BYPASS LED to turn red. You are now in preset mode.
Set up the effect how you want it to sound, including the EFFECT SWITCH, LEVEL KNOB, DRIVE KNOB, BASS KNOB, and TREBLE KNOB. Once you have made a change, the ENGAGE/BYPASS LED will begin to blink.
To save your preset, hold the footswitch until the ENGAGE/BYPASS LED blinks rapidly 3 times.
Now you can engage and bypass the L.A. Lady using the ON/OFF FOOTSWITCH, and each time you engage the effect, your saved preset will be recalled.

Editing a Preset
Activate your preset (the ENGAGE/BYPASS LED will be solid red).
Change any parameter you wish (EFFECT SWITCH, LEVEL KNOB, DRIVE KNOB, BASS KNOB, and TREBLE KNOB). Once you have made a change, the ENGAGE/BYPASS LED will begin to blink.
When you are ready to save, press and hold the ON/OFF FOOTSWITCH for a few seconds. The ENGAGE/BYPASS LED will blink three times to show that the preset was saved.
Exiting Preset Mode
When Preset Mode is active, bypass the effect using the ON/OFF FOOTSWITCH. The ENGAGE/BYPASS LED should be dark at this time.
Press and hold the ON/OFF FOOTSWITCH for 5 seconds and wait for the ENGAGE/BYPASS LED to turn green. You have now exited Preset Mode.
Universal Bypass TM
Most effect pedals offer either true bypass or buffered bypass. The L.A. Lady contains two separate circuits for bypass mode, allowing you to choose the method you prefer. The true bypass path uses signal relays, which are electromechanical switches. This provides an ultra-low resistance path from the input jacks to the output jacks, which is effectively the same as a wire. The buffered bypass path uses extremely low noise buffers, which provide a very low output impedance and are effective for driving long cables or long chains of effects following the L.A. Lady’s audio output.
Out of the box, the L.A. Lady operates in true bypass mode. In order to switch to buffered bypass mode, edit the L.A. Lady’s global settings using the Neuro App.
We recommend you choose between the active analog bypass (a.k.a. buffered bypass) and relaybased true bypass based on what is needed in your signal chain. Ideally, the first pedal in a signal chain is a buffered input followed by true bypass in the rest of the signal chain.
Both bypass methods have pros and cons associated with them. Buffered bypass provides consistent input impedance so that if the source is susceptible to variations in input impedance (similar to a guitar pickup), there won’t be a noticeable change in tone. True bypass has the benefit of providing a dedicated hardwired bypass signal path. The L.A. Lady features small-signal relays for true bypass switching that offer reduced pops and clicks compared to the traditional true bypass switching method using a mechanical switch.
Stacking and Parallel Processing “Inside the Box”
The L.A. Lady works great as a simple mono Overdrive effect, but it has the power to do much more. Within the L.A. Lady, two completely independent overdrive, fuzz, or distortion circuits can be set up to run stacked (in series), in parallel (side-by-side and mixed), or even in true stereo. Usually, this would require two separate distortion pedals, but the L.A. Lady can do it all on its own.
Stacking (Series / Cascaded)
Stacking overdrive, fuzz, and distortion pedals is a common method for creating unique textures that would not be possible with a single pedal. This normally involves putting two pedals in series, one after the other, to create multiple gain stages. Typically, this requires two separate distortion pedals,
