Increasing the intensity to create infinite repeats and manually adjusting the echo volume can produce unique, controlled soundscapes.

Some users run multiple RE-20 units in series for various delay effects: slapback, tap tempo, and long ambient echoes.

The RE-20 is noted for producing a unique pitch effect when changing modes while delays are feeding back, a feature missing in the RE-202.

The RE-20's tap tempo allows for easy quarter note tapping across all modes, unlike the RE-202, which requires switching to mode 1 for the same effect.

The RE-20's maximum delay time is 6 seconds, significantly longer than the RE-202's 2-second maximum in long mode, impacting extended ambient soundscapes.

The RE-20 includes a preamp that emulates the original effect, always on, unlike the adjustable preamp in newer models.

The RE-20 allows control over echo level with an expression pedal, affecting delay signal intensity without altering the dry or reverb sections.

The RE-20, despite being an older model, was one of the first tape delay pedals to incorporate tap tempo functionality.

The pedal's multi-head selection offers versatility with options for echo, reverb, or both simultaneously.

The RE-20 is praised for its ability to create a "modulated delay soup," with a flangey sound that subtly hangs in the background, unlike the punchier presence of the RE-202.

Some owners prefer the RE-20's oscillation and echo sound over more modern alternatives like the Strymon Timeline due to familiarity and tonal preference.

The RE-20 is considered a straightforward emulation of the original RE-201, while the newer RE-202 adds features like adjustable tape "age" and additional reverb types.

Some owners report that the RE-20's repeats have a laid-back presence, making it challenging for rhythmic delay but ideal for melding into the background with long feedback times.

Users note that the RE-20's reverb can be underwhelming alone, but when mixed subtly with delay, it contributes positively to the overall sound.

Owners highlight the RE-20's unique capability for creating ambient, spacious sounds, often comparing it favorably to newer models.

Adding a $30 bypass loop pedal allows users to manage the RE-20's always-on master volume and potential clipping, enhancing compatibility with high-end amps.

To avoid tone suck from the always-on preamp, users suggest placing the RE-20 in an effects loop using a bypass pedal.

With the RE-20 out of production, used models range from $233 to $306, offering a more affordable alternative to the newer, pricier RE-202.
