Introducing the Lamb, 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 asymmetrical clipping with 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 altogether however this will push the op amp into saturation creating op amp breakup for a slightly different feel.
Each circuit offers varying amounts of headroom, so typically when switching between these circuits your output volume will jump around quite a bit. At JET Pedals, we've added our volume leveling technology (VLT) to each circuit so you don't experience any jumps in volume when switching between circuits. This allows you to really feel the difference between the various circuit types, rather than simply hearing a perceived difference with volume jumps.
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 found on all BluesBreaker type pedals, allowing you subtract bass or treble frequencies. 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. The Mid Boost is designed to be a subtle improvement to your tone, we did not want this to be an overpowering tone shaping tool but rather something that is most noticeable once it's been removed from the signal path.
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 you 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 / High Cut Knob LED
- Cyan - symmetrical silicone diodes
- White - asymmetrical silicone diodes
- Yellow - clipping diodes removed (op amp clipping)
- Preset / Volume Knob LED
- UV (purple) - preset #0
- Red - preset #1
- Green - preset #2
- Our soft click Bypass and Preset switches are smart switches which have several different timed based functions to control various features of the pedal. Since there is a lot of time based magic happening behind the scenes, please note the following time based functions
- Time based functions are as follows:
- To switch circuits on the fly, press and hold the Bypass switch for at least ½ of a second and upon releasing the switch you will cycle through to the next circuit. Once you've reached the end, the next long press will cycle back to the first circuit.
- To switch presets on the fly, press and hold the Preset switch for at least ½ of a second and upon releasing the Preset switch you will cycle through to the next preset, once you've reached the end, the next long press will cycle back to the first preset. You can cycle through your presets in any state that the pedal is in (off, on, or in preset mode).
- To enter "Preset Save Mode", press and hold both the Bypass and Preset switch until the Bypass LED will begin to flash, confirming you are in "Preset Save Mode".
- A short press of the Bypass switch will cycle through the circuits
- A short press of the Preset switch will through where to store the preset
- Once you've selected the right circuit and preset location, simply set the knobs to your desired positions and do a long press of the Preset switch. Once releasing the switch, the Preset LED will flash rapidly letting you know you've just saved that preset. Repeat as necessary to save your other presets
- To exit "Preset Save Mode", press and hold the Bypass switch for longer than 2 seconds and upon releasing the Bypass switch you will exit the "Preset Save Mode"
- To engage the Lead. Boost, simply do a double press of the Preset switch.
MIDI Features & ControlsMidi communication to the Lamb conforms to the specification for TRS to Midi adapters issued by the Midi Association. So what does this mean for me? In order to communicate via Midi you will need either a 5 pin to 1/4" TRS adapter cable that is wired to the TRS specification (link to a compatible cable found here) or if you wish to make your own patch cables, a link to the wiring diagram and the midi specification can be found here. You can also use a midi box that converts 5 pin Midi to multiple TRS patch cable connections and will need to conform to the TRS specification, or a compatible Midi controller with TRS midi output's may be used to control the Lamb.
Changing the Midi Channel
From the factory the Lamb is set to receive Midi messages on Midi channel 1, however this can be changed upon powering up the pedal. After applying power to the Lamb, hold down the Preset 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 Preset switch, the Bypass LED will flash the number of times equivalent to the Midi channel (set to 1 from the factory) and then will have a 2 second pause before flashing again. Simply press the Bypass switch to increment the Midi channel by 1, press as many times necessary to change to the correct Midi channel. The numbers available on the Lamb are channels 1 thru 16, once you've reached number 16 the next press will start over again at number 1. Once you have the right number selected, just release the Preset switch to save this setting into permanent memory.
Unlimited Presets or Save Up to 100 Built-In Presets
You have two options for creating presets. The first option is to use a "smart" midi controller, like the JET Pedals MCX, that can send multiple simultaneous midi messages. Just send individual CC messages to turn the Bypass switch on, select the circuit, and set the values for each knob. The Lamb can receive multiple simultaneous midi messages so you can create unlimited presets with the right midi controller.
The second option is to use our revolutionary CC Snapshot feature. While in Live Mode, select your desired circuit and then set all of the knobs to their desired positions. From there just send midi CC #28 with any Value from 3 thru 99. The pedal will then take a snapshot of its circuit and knob positions, after that the knobs will flash green letting you know the preset has been saved into permanent memory. To recall this preset, just send a PC message with the same number used for the Value when sending CC #28.
Example: send CC #28 Value 10 to save a preset in the 10th slot. Send PC #10 to recall the new preset.
Sending Program Change Messages
Sending PC messages will recall the onboard presets stored within the Revelation
- PC #0 - Recalls the first preset (UV)
- PC #1 - Recalls the second preset (Red)
- PC #2 - Recalls the third preset (Green)
- PC #3 - #99 Recalls the preset created by CC Snapshot (Blue)
- In this mode all of the LED's will be blue and the knobs will be active in case you need to make changes on the fly. Since every preset 3-99 will be the same color, it may be hard to remember what's been saved to each preset location. No worries, if you move the knobs away from their original position, the color of the LED's will change and when moved back to the saved preset location the LED's light up blue again. For the Drive and Tone knobs (that don't have an illuminated knob) the Preset and Bypass LED's will begin to flash when moved away from the saved position and return to full on when you navigate back to the saved preset location.
Sending Control Change Messages
Sending CC messages will control the individual controls, knobs, and switches of the Lamb. Each knob on the Lamb is broken into 8 different sections, 1 is the equivalent of having the knob turned completely counter-clockwise and 8 is like having the knob turned completely clockwise. Similarly, 4 & 5 will be just to the left and right of straight up on the knob.
- CC #19 with any value of 1 thru 8 controls the Volume knob.
- CC #20 with any value of 1 thru 8 controls the Gain knob.
- CC #21 with any value of 1 thru 8 controls the Tone knob
- CC #22 with any value of 1 thru 8 controls the Mid Boost knob
- CC #23
- Any value between 0 & 63 turns the Bypass switch off
- Any value between 64 & 127 turns the Bypass switch on
- CC #24
- Any value between 0 & 63 turns the Preset switch off
- Any value between 64 & 127 turns the Preset switch on
- CC #25 any value between 0 & 127 increments the Preset number
- CC #26 any value between 0 & 127 decrements the Preset number
- CC #27
- Any value between 0 & 42 activates circuit #1 (symmetrical silicone diodes)
- Any value between 43 & 85 activates circuit #2 (asymmetrical silicone diodes)
- Any value between 86 & 127 activates circuit #3 (clipping diodes removed)
- CC #28 any value between 3 & 124 activates CC Snapshot mode
- This takes a snapshot of your current settings and stores it permanent memory at the appropriate preset location. An example would be to send CC #28 Value 3, this stores a preset in the 3rd slot and can be recalled anytime by sending PC #3
- CC #29
- Any value between 0 & 63 turns off the Lead Boost
- Any value between 64 & 127 turns on the Lead Boost
(you can also exit the Lead Boost with the Preset foot switch as well)
