From Yamaha –

Delay is at the heart of many multi-effect tones. Yet many guitarists use it simply to create echo effects or to replicate the solid slapback sound that's been around since the Fifties. Players with more adventurous aims will find plenty to like about Yamaha's UD-Stomp. With its powerful delay processing abilities  this effects processor lets you rediscover delay's vast potential for creating tones that go beyond the ordinary.

At the centre of the UD-Stomp are eight delay circuits. They can be run in parallel  with each offering up to 700 milliseconds of delay  or ganged in series to allow a whopping 5.5 seconds of delay. Each features variable parameters for delay time  feedback (repeats)  high- and low-cut filters  pan position (for when the UD-Stomp is used in stereo situations)  phase  tap and modulation.

The tap function provides control over the delay time of each circuit relative to the other circuits  allowing you to create interesting rhythmic effects  including bizarre-sounding stutters. The UD-Stomp's modulation function  on the other hand  lets you create shimmering chorus and vibrato effects  as well as Doppler-like effects  in which the pitch descends as the sound repeats. 

The Delay Chain
The UD-Stomp's eight delay bands can be joined in series or in parallel  or in a combination of both. When two or more delay lines operate in parallel  they act independently on the input signal; each can have its own tap  pan  filter and modulation settings. You can use this method to set up ping-pong and panning delays  or to create a flange effect on one band while producing long  repeating delays on another.

In series mode  the first band in the signal path feeds the next  and the final delay time is a combination of all the bands in the path. This is how the UD-Stomp can achieve very long delays  which are useful when you want to set up the processor for loop- and sample-style delays. But even when you're using just two delay bands  you can create delay times of more than one second and still have six bands left to work with.

Real-Time Control
The UD-Stomp has four footswitches that provide real-time control over the unit. The four-button layout is friendly to look at but some of its operations are cumbersome. For example,  to activate tap tempo  you must hold down one footswitch for several seconds  use another to select the band to be controlled and hit a third button to set the tempo time.

The UD-Stomp's 180 presets (90 user-writable) are organized into groups  each of which contains three banks of three effects. Switching within a bank is easy but switching banks within a group takes more care  and switching among groups is tricky. None of this will matter in the studio but onstage it could be distracting.

On the plus side  the unit's front panel has dedicated knobs for most editing functions  and the UD-Stomp offers MIDI control over almost every parameter. You can also hook up a control pedal and route it to various parameters (such as delay time  level or feedback)  then store the new values per patch or globally.

With 20-bit D/A and a sample rate of 44.1kHz  the UD-Stomp preserves the character and warmth of your guitar's tone while it creates truly breathtaking effects. The effects engine is incredibly versatile  and I especially like being able to have independent delays and modulation effects in a single preset. The factory settings  some of which were designed by jazz-fusion guitarist Allan Holdsworth  cover a wide range of effects  from the basics  such as chorus to tape delay  to some that are just plain bizarre.

The Bottom Line
Anyone who's into tweaking tone will love the UD-Stomp-there's simply no other floor-mounted delay like it. Although it would probably be hard to take full advantage of its features onstage  the UD-Stomp more than makes up for its complexities with effects that are rich  rewarding and truly out of this world.

This unit is in good original condition. It has been used only sporadically over the years and is in excellent working order. The Yamaha UD Stomp is a sophisticated soundscaping device which is no longer manufactured, but remains in demand. In recent times these have been selling second hand for over USD$1000.

Comes in its original box with full operating manual, power supply and substantial patch list so you can easily emulate the settings of Alan Holdsworth (27 actual Holdsworth patches) as well as dozens of other classic soundscapes.
