The Lamb is a 100% all analog signal path, programmable overdrive pedal with onboard presets and full midi control. The Lamb is an op amp based overdrive circuit with soft clipping diodes placed inside the feedback loop of the op amp. While it is it's own unique circuit, it can be closely compared to similar type circuits like the Marshall BluesBreaker, Analog Man King of Tone, and JHS Morning Glory, etc. The Lamb features an internal 18V charge pump converting a standard 9V power supply to 18V for maximum headroom and responsive touch dynamics.

The Overdrive Circuits 
The Lamb has three different circuits which offer different levels of compression and clarity. By default the Lamb loads up with quad symmetrical silicone diodes which offers the least amount of compression for maximum clarity and "tube" like breakup. Then we offer symmetrical clipping with dual silicone diodes, this offers a slightly more compressed sound creating a more complex tone with rich overtones and saturation. The last option removes the clipping diodes from the bottom half of the sign wave which creates asymmetrical clipping on the top half of the sign wave. This option has much more headroom than the other two and is great for running a low gain / high volume type of overdrive to really push your amp into natural saturation.
Lead Boost 
Double tap the Preset switch to auto engage the Lead Boost. The volume of the Lead Boost is user definable and can be changed/stored in permanent memory via the configuration menu at startup. The Lead Boost can be adjusted from 1 thru 4, by default it is set to 1 from the factory. This can be changed upon powering up the pedal. After applying power to the Lamb, hold down the Bypass switch while the pedal is in startup mode (Volume & Mid Boost knobs are white and the Bypass and Preset LED's are flashing). While continuing to hold down on the Bypass switch, the Preset LED will flash the number of times equivalent to the Lead Boost (set to 1 from the factory) and then will have a 2 second pause before flashing again. Simply press the Preset switch to increment the Lead Boost by 1, press as many times necessary to change to the desired setting. Once you've reached number 4 the next press will start over again at number 1. Once you have the right number selected, just release the Bypass switch to save this setting into permanent memory.
The Tone Stack 
The tone stack of the Lamb offers complete flexibility for maximum tone shaping. Inside the Lamb is a trim pot that is adjustable to set the overall presence of the Lamb, use this to fine tune your sound based on which amp and/or guitar combo you are using. The Lamb has the standard tone knob (low pass filter) found on all BluesBreaker type pedals, allowing you subtract or add treble frequencies. The gain knob also provides a dual role, at lower gain settings it adds bass and at higher settings it removes bass to eliminate flub or unwanted overloading of the low frequencies at high gains. We've also added a unique feature to the Lamb, a Mid Boost knob, which allows you to dial in just the right amount of mids to help cut through the mix. Think of the Mid Boost knob as a volume control, all the way to the left is off, turning clockwise will increase the amount of mids introduced into the signal path.
The Workflow 
The workflow of the Lamb is similar to our Revelation Reverb, you have a "Live" mode and a "Preset" mode. When you press the Bypass switch, you will be in "Live" mode, the knobs will all be active and you can adjust to your desired sound. Pressing the Preset switch will jump into "Preset" mode, when here you immediately jump to the cue'd up preset and the knobs now become inactive. Pressing the "Preset" switch again will disengage the "Preset" mode and you immediately jump back to "Live" mode.
Just like our super popular Revelation Reverb, the Volume knob and the Mid Boost knob are illuminated with multi-colored LED's to indicate the status of which preset is cue'd up as well as which circuit the "Live" mode is in. To switch between circuits, simply do a long press (press and hold for at least ½ of a second) of the Bypass switch. Upon releasing the switch the LED on the Mid Boost knob will change colors indicating that you've changed circuits. To switch between presets, and/or cue up your desired preset while in "Live" mode, simply do a long press of the Preset switch. Upon releasing the switch the LED on the Volume knob will change colors indicating that you've either jumped to the next preset (while in "Preset" mode) or have cue'd up the next preset while in "Live" mode.
The colors of each knob are as follows:
Circuit / Mid Boost Knob LED
Cyan - symmetrical quad silicone diodes
White - symmetrical dual silicone diodes
Yellow - clipping diodes removed from bottom half of sign wave
Preset / Volume Knob LED
UV (purple) - preset #0
Red - preset #1
Green - preset #2
