By using FTT’s original algorithm, the AMBI SPACE combines various elements to achieve a mechanism for producing complex reverberation, through the use of a 32-bit dual core chip and a 32-bit high precision DSP. While the high quality, natural and musical sounding reverberation realized in this compact device can of course be used for electric guitars and basses, as well as for acoustic guitars and vocals, it is equally at home in other situations, such as recording and mixing.

In FTT’s newly developed and original reverb sounds “CAVE” and “SERENE”, the early reflections and late reverberation are added in multiple steps to realize a complex harmonic structure comprising enhanced frequency components, all of which creates an almost magical, transparent and spatial sounding reverb like you’ve never heard before. These new reverb sounds will stimulate your imagination.

By combining all of the analog and digital know-how accumulated so far by Free The Tone, the reverb effects unit AMBI SPACE was finally born after a long development period. Try it out and feel its sound.

Key features

  • The AMBI SPACE uses a dual core chip with a 32-bit main CPU and 32-bit co-processor and performs high speed calculations using the 32-bit high precision DSP to generate sounds comparable to those from rack mount effects units, although it is actually a compact effects unit.
  • Up to four settings of all knobs can be memorized as presets.
  • These four presets can be recalled by MIDI program-change numbers.
  • Six reverb modes are provided: SPRING, PLATE, ROOM, HALL, CAVE, and SERENE.
  • In Free The Tone’s unique reverb modes “CAVE” and “SERENE”, sounds with a rich harmonic structure are created by complex reverberation patterns being added to the reverb sound in multiple stages to realize unprecedented, transparent and spatial reverb sounds.
  • Original (dry) sounds pass through the unit from input to output as analog signals and are mixed with reverb sounds by the internal analog mixer, so the unit can output signals without spoiling the original sound quality.
  • The unit contains one of the major features of the Free The Tone products, the HTS (Holistic Tonal Solution) circuit. It manages signals comprehensively from input to output so that there is no change in sound character when the effect is turned on or off.

Delay

A delay pedal records your signal and plays it back after a set time, creating echoes that can range from tight, slapback repeats to long, atmospheric trails. It’s one of the most versatile effects, used to thicken tones, add rhythmic depth, or build spacious, ambient layers. Analogue delays offer warm, decaying repeats that blend naturally with your tone, while digital units provide pristine echoes with precise control over time, feedback, and mix levels.

From classic rockabilly and tape-style echoes to modern looping and shimmer effects, delay pedals have become essential tools for shaping sound. They can make solos soar, rhythms pulse, or transform simple chord progressions into cinematic textures. Whether used subtly to add dimension or boldly to create soundscapes, a good delay pedal can completely redefine the feel and atmosphere of your music.

MIDI

MIDI pedals use the Musical Instrument Digital Interface standard to communicate with other guitar pedals, effects units, and hardware. They allow control over presets, parameters, and switching across multiple devices from a single controller. MIDI integration makes it possible to build complex, synchronised pedal setups while keeping control simple and consistent.

New

This is brand new, fresh in, and a UK warranty is included. New Gear always comes from trusted UK music retailers.

Reverb

A reverb pedal is like the rich sauce that ties every flavour on the plate into one smooth experience. It adds depth, warmth, and atmosphere — the sonic equivalent of a perfectly reduced glaze that lingers on the tongue. Whether you’re after the subtle ambience of a cosy café (spring or plate reverb) or the grand echoes of a cathedral (hall or shimmer reverb), this is where your tone breathes and expands. A touch of reverb can turn a dry sound into something lush and inviting — but pour on too much, and it’s all you can taste. Used with finesse, it’s the finishing touch that transforms your tone from plain to unforgettable.
