Connections Before making any connections to any of the UD-Stomp’s INPUT and/or OUTPUT jacks, make sure that the power on the UD-Stomp and all other devices is turned OFF to prevent electrical shock or damage to the devices. ■ Connecting the Power ■ Connecting the UD-Stomp Use the supplied power adaptor (AC-10) to supply power to the UD-Stomp. Since the UD-Stomp is a delay effect, it should be connected to the end of the effect chain when used with other effects.
Connections ■ Connecting Headphones Connect a pair of headphones to the PHONES jack (standard stereo) on the UD-Stomp to play or practice in private. The volume of the headphones can be controlled with the OUTPUT knob. * When a pair of headphones is connected, the output from the OUTPUT jack and the DIGITAL OUT jack will still deliver sound output. When using headphones, use at a comfortable volume so as not to cause shock to your hearing.
Using the UD-Stomp The UD-Stomp is an effects processor that is equipped with eight identical delay circuits. It provides you with the power and freedom to create complex sounds by connecting multiple delay circuits in a series, or combine any or all of the individual circuits into a single, long delay, etc. This section will use some of the UD-Stomp’s preset programs as examples to help you understand how the parameters and functions work. ■ Preparation 1.
Using the UD-Stomp Selecting an Effect Band Let’s first select a delay circuit and set its parameters. The [EFFECT BAND 1-8] buttons are used to switch the eight effect circuits ON/OFF. 1. • If the [UP] lamp flashes when the knob is rotated, rotate the knob to the right (toward 10), and if the [DOWN] lamp flashes, rotate the knob to the left (toward 0). At this time, the knob’s parameter value set in the current patch is flashing in the display.
Using the UD-Stomp PAN Setting the Feedback Up to this point we have set the delay time so a single delay sound is produced 250msec after the original sound. Next, set the Feedback parameter to determine how many times the delay will repeat. 4. Rotate the FEEDBACK knob so that “10.0” appears in the display. The delay sound is repeated infinitely without fading out. When the FEEDBACK is set to a lower value, the number of times the delay is repeated will decrease and the delay sound will fade out.
Using the UD-Stomp Setting the Modulation Delay Circuit Adding Modulation to the Delay Time causes the delay sound’s pitch to change. This can be used to create effects such as chorus, flanger, etc. TAP=66.6% 240msec TAP=100% 360msec Delay sound from Effect Band 1 Delay sound from Effect Band 2 Original Sound 13. Recall patch “9.11” again. 14. Press the [EFFECT BAND 1] button and use the TIME COARSE knob to set the delay time to “600.” 15. Set the SPEED knob to “4.0” and the DEPTH knob to “10.
Using the UD-Stomp Now Effect Bands 1 and 2 are connected as shown in the illustration below. IN BAND 1 IN BAND 2 IN BAND 1 1 BAND 4 IN BAND 8 8 BAND 5 IN BAND 3 3 BAND 6 series. Press the [EFFECT BAND 2] button, then hold the [CONNECT] button and press the [UP] button so that “1” is shown in the display. The output signal of Effect Band 1 (the original sound mixed with the delay sound) is now sent to the input of Effect Band 2. Effect Band 1 and Effect Band 2 are now connected in a series.
