The Caline CP-507 Mariana is a compact reverb pedal with a twist: instead of one reverb voice, it carries seven presets, each a modulated reverb, and three knobs whose job changes depending on which preset you pick. Pedal of the Day describes it as cramming seven "Out-of-this-World" modulated reverbs into one compact pedal1. It sits in Caline's line of affordable reverbs alongside the CP-508 Wonderland, which the same review covered as a companion ambient reverb machine1.
What it does
The Mariana's core idea is seven different types of modulated reverbs, or delays, in a single box. Delicious Audio's buying guide, by Christopher Scapelliti and Paolo De Gregorio, describes it as super-affordable, offering seven different types of modulated reverbs (or delays), with three knobs that control different parameters depending on the selected mode2. That means the pedal is not one reverb with trim controls: each preset is its own voice, and the same physical knob can serve a different function from one mode to the next.
Pedal of the Day frames the flexibility the same way: with three independent controls affecting each of the seven presets, there is literally no end to the possibilities1. For a player, that layout points toward soundscape and ambient work rather than a straight spring or plate simulation, since modulation is built into every preset.
What reviewers said
"An amazingly versatile tool to create sonic soundscapes the like of which you have only dreamed of."
Pedal of the Day's verdict was that the Mariana offers amazing value for the money, as well as endless potential1. Delicious Audio included the Mariana in its roundup of hybrid reverbs that add modulation, tremolo, or fuzz and distortion to a reverb core, placing it among the affordable options in that field2.

Questions
How many reverb types does the Caline CP-507 Mariana have?
The Mariana carries seven presets, which Pedal of the Day describes as seven 'Out-of-this-World' modulated reverbs in one compact pedal. Delicious Audio's buying guide counts the same seven modes, noting that they cover modulated reverbs or delays, with three knobs that control different parameters depending on the selected mode.
What do the three knobs on the Mariana do?
The three controls are independent but their effect changes with the preset: Pedal of the Day describes three independent controls affecting each of the seven presets, and Delicious Audio says the three knobs control different parameters depending on the selected mode. So the same knob can do a different job in each mode.
What did reviewers say about the Mariana?
Pedal of the Day called it an amazingly versatile tool to create sonic soundscapes, and found it offered amazing value for the money as well as endless potential. Delicious Audio's buying guide describes it as super-affordable and lists it among hybrid reverbs with modulation.
