FLAMMA's reverb and delay effector, the FS22 EKOVERB. It has some scratches and dirt from use, but it works well. Accessories include the box and printed materials. Feel free to ask if you have any questions! The FLAMMA FS22 Ekoverb is a convenient spatial effects unit equipped with three types of reverb and delay each. In addition to standard effects, it also features slightly unusual effects such as reverse delay and shimmer reverb, making it a minimalist yet playful unit for guitarists. The input/output is dual mono with two TS jacks each. It can of course be used with mono input/output like a normal effector, and supports various routings. The eight knobs that control the sound are arranged with the left four controlling the delay and the right four controlling the reverb, a layout also seen on the Strymon Flint, etc. The "LEVEL", "TIME", "TONE", and "FEEDBACK" knobs on the delay side adjust the volume of the delay effect, the time until the sound returns, the character, and the number of times the sound bounces back, respectively. The "LEVEL", "DECAY", "TONE", and "PRE-DELAY" knobs on the reverb side adjust the volume of the reverb effect, the decay time, the character, and the time from when the original sound is input until the reverb effect sounds, respectively. In recent years, there are many spatial pedals, especially modern spec reverbs equipped with shimmer, etc., that have complex controls that are difficult for beginners to handle. However, the controls of the FS22 Ekoverb are limited to the minimum basic functions, so even beginners can create sounds without hesitation.
