The Alluring Echo is a tape echo-style delay pedal that is based on the Magnetic Echo. It features a PT2399-based delay chip that produces lo-fi repeats ranging from 40-600ms. If you want, you can modify the circuit to achieve even longer delay times. The pedal also includes modulation effects to emulate wow and flutter.The controls on the Alluring Echo are as follows:1. Time: Adjusts the length of the delay.2. Regen: Controls the number of repeats, ranging from a single repeat to oscillating indefinitely.3. Depth: Determines the intensity of the modulation effect, from a subtle shimmer to a more pronounced pitch shift and chorus.4. Level: Sets the volume of the repeated echoes.5. Speed: Controls the speed of the modulation effect.An LED indicator provides visual feedback on the modulation section, with a brighter light indicating deeper modulation. The LED also flashes in time with the modulation effect.The circuit board is designed for 3mm resistors, which can be challenging to work with due to their small size and difficult-to-read codes. However, the end results are worth the effort. If you prefer, 6mm resistors can be supplied, but they will need to be mounted upright on the PCB. The LFO section of the circuit requires a small modification to add a missing resistor, but it is a simple task that does not affect the overall build. Future batches of the pedal will have this correction implemented.There is an option to choose a slightly modified version of the pedal that extends the delay time. However, it is important to note that increasing the delay time will also introduce more noise and lo-fi glitchiness. This may not necessarily be a bad thing, depending on your preferences. Additionally, you can choose to include an external gain pot, but it is recommended to stick with the default set and forget trimmer.
