Ledges®
Tri-Dimensional Reverberation Machine

Ledges is a compact, three-mode reverb with the ability to save and recall six presets and user-assignable expression control with loads of customizable options. If you’re craving that warm, lush reverb tone from the players and songs you love, then this is your pedal. If you want to push the limits and take it further to sonic reaches that only you can uncover, then this is also your pedal. It’s everything you’ve ever wanted and needed out of a reverb.

We created Ledges for no-nonsense musicians who need access to a wide variety of fantastic sounds and don’t want to mess with menu diving, extra footswitches, or midi controllers. Ledges offers three distinct, rich reverbs that cover all your bases - Room, Hall and the almost infinitely regenerating Plate - with user assignable expression control and six presets to easily switch between settings. Presets can even save expression pedal assignments, making it easier than ever to save and switch between the 6 best reverb sounds that are yours and yours alone.

Ledges has three unique reverb modes: Room, Hall and Plate. Each mode uses a different algorithm, tuned to give specific spatial qualities, while still sitting perfectly in the mix. We steered clear of any tones that were harsh or muddy.

Three Handcrafted Reverb Modes

Mode R: Room Reverb

Room (R) has the darkest tone of the three modes. At the shortest length setting it’s like a small, boxy room, reminiscent of 80s reverb. As you bring the length up, the reflections become distant and brighter; similar to playing in a large tile room. If you hit the strings harder, it has an almost spring reverb character without becoming completely washed out.

Mode H: Hall Reverb

Hall’s (H) shortest length setting picks up where the longest length of Room leaves off. Hall shifts from a large hall to a massive cathedral with loads of soft, distant reflections that build up faster and trail off longer.

Mode P: Plate Reverb

Plate (P) goes from a traditional, large plate to a nearly infinite pad of reflections that create a regenerative freeze-like effect that gradually decays. At the shortest length setting, the decay of the Plate picks up where Hall leaves off. At the longest length setting, the highest frequencies of the reverb are recirculated, generating a nearly infinite ambient pad of bouncy reflections underneath your initial attack that can go to the verge of self-oscillation. The recirculated pad can be further fine-tuned with the damping control to sit just right in the mix.

Pro Tip: Ledges is buffered bypass to allow the reverb to naturally decay when bypassed. You can create a dense ambient pad, bypass the pedal and play over top of your naturally decaying micro-loop. Get 2 or 3 Ledges and make a mini reverb version of Frippertronics!

Global Features

Presets

Ledges boasts six presets and on-the-fly footswitch preset switching, with expression control that can be mapped to different controls and can also be saved as a preset.

Saving, recalling and overwriting presets has never been simpler.

To save a preset, turn the Preset rotary switch to the desired location you wish to save your preset. Dial in the mode and settings you want to save (including the expression pedal assignment!), hold the save/recall switch down until the LED flashes between green and red, and then release. Your preset is saved!

To recall a preset, just select the desired preset you wish to use with the Preset selector switch and do one of the two following actions:

1. When the pedal is activated and the effect is in use, hold the foot switch down for at least 0.75 seconds, and it will switch from Live mode to Preset mode. 
2. Tap the lighted Save/Recall switch. The switch will turn from green to red, indicating you are now in Preset mode. Tap again and the switch will turn from red to green, indicating you are in Live mode.

Operating Modes

Ledges has two operating modes which are indicated by the color of the Save/Recall switch LED. In Live mode, the pedal will operate exactly where the controls are set and any changes will have no effect on the presets unless saved. In Preset mode, stored presets, including expression pedal mapping, are selected using the Preset switch, and the physical settings of the controls will be ignored. 

When the pedal is activated and the effect is in use, hold down the foot switch for at least 0.75 seconds and it will switch from Live mode to Preset mode. With Ledges, it’s never been easier to switch between Live and Preset modes on the fly, vastly expanding your sonic cosmos - no bending down required!

User-Assignable Expression Control

You can easily map an expression pedal to any of the controls, allowing for limitless experimentation. Ledges comes with the expression jack mapped to the Damping control, but to reassign it, just insert the expression pedal into the EXP jack, place the expression pedal in the toe down position, turn the control (any amount and in any direction) on the Ledges that you wish to put under control of the expression pedal, put the expression pedal in the heel down position, and voila! This control is now assigned to the expression jack and can be controlled by an expression pedal.

Controls

Length: Sets the length of the reverb.

Mix: Adjusts the level of the reverb.

Damping: Tames the treble in the reverb reflections.

Presets: Ledges has six available preset slots for you to save and recall your favorite settings. The settings for each of the three controls, the mode switch and the expression jack assignment can be saved and recalled in any of the slots.

Tech Specs

• Dimensions: 4.75 x 2.50 x 2.25 in. (121 x 64 x 57 mm) with knobs
• Current Draw: 80 mA
• Input Impedance: 1 MΩ
• Output Impedance: 100 Ω
• TRS expression pedal wiring:
  Tip: Wiper
  Ring: +3.3V
  Sleeve: Ground
• Flexi-Switch® Technology

This device features Flexi-Switch® Technology! This relay-based, true bypass switching style allows you to simultaneously use momentary and latching style switching.

• For standard latching operation, tap the footswitch once to activate the effect and then tap again to bypass.
• For momentary operation, hold the footswitch down for as long as you’d like to use the effect. Once you release the switch the effect will be bypassed.

Ledges is buffered bypass with tails. Power is required to pass signal.

Power

This device takes a standard 9 volt DC power supply with a 2.1mm negative center barrel. We always recommend pedal-specific, transformer-isolated wall-wart power supplies or multiple isolated-output supplies. Pedals will make extra noise if there is ripple or unclean power. Switching-type power supplies, daisy chains and non-pedal specific power supplies do not filter dirty power as well and let through unwanted noise.

DO NOT RUN AT HIGHER VOLTAGES!
