This tutorial demonstrates how to build Delaytion™, PedalSync's analog delay control station, which features tap tempo, modulation, and four program storage.

 

Delaytion can control most analog delays, including Dunlop's MXR Carbon Copy delay, Malekko Ekko 616 delay, and Build Your Own Clone's Analog Delay.

First etch your circuit board using this verified layout: Delaytion PCB Layout

(right click to save)

Drill the PCB, noting that the 4001 diode has slightly larger holes (seen under the black mark on PCB).

Use consecutive bits to accurately drill the button holes in the PCB:
1/8", 1/4", 3/8", 15/32"

It is critical to have the button holes drilled accurately, as the enclosure components are tightly packed.

Trim to the outline edges.

Populate the circuit board based on this: Delaytion Board Layout Diagram

Connect the nine (9) jumper wires identified in the Layout Diagram (A, B, C, D, E, F, H, I, J)
(D-D is bare in the photo)

Note that there are no jumpers required if you purchased the printed circuit board.

Ground the correct pins for chip select (CS1 and CS2 in the Layout Diagram). For the Carbon Copy, ground CS2. For the BYOC Analog Delay, ground both.

Click this link for the Delaytion Schematic which includes a Chip Select table.

Make a small loop in four pieces of bare hookup wire (about 3/4") and run those wires through the holes for the button connections from the back, then solder in place. Clip off the loops.

Insert the pushbutton switches from the top and secure them on the back side of the circuit board with a double-thick nut. Add an extra regular nut to obtain the proper spacing of approx. 1/4".

Bend the switch hookup wires through the pushbutton lug holes (while clipping the excecss) and solder in place.

 

Put 0.12" spacers on the the LEDs, then run the leads through the holes, noting polarity. Bend the leads back up through the circuit board and solder on the adjacent pads.

Note that the LEDs are simply soldered to their pads if you purchased the Printed Circuit Board (no adjacent pads).

 

Connect the two power wires and test the LEDs and pushbuttons before installing.

Print out this template: Delaytion Drill Hole Template

(right click to save)

If it does not size correctly, insert the template jpg it into a Word file.

Cut it out and carefully and center it on the 1590B enclosure, securing it with electrical tape.

Using an awl and dead-blow hammer, mark the drill hole locations (shown by the small white center dots).

Drill out all holes at 1/8".

This includes the two back-panel holes, which need to be 2/3 of the way to the bottom of the enclosure, and centered between the pots.

Drill out the top holes to the following sizes:

13/64" - Toggle Switches

15/32" - Pushbutton Footswitches

#8 (.199) - LED holes

9/32" - Potentiometers

1/8" - Pot Side Holes - Insert the pot on top, upside down and scratch the enclsoure with the pin to find the drill hole edge as shown in the photo.

Back Panel holes:

1/4" - RCA jack
15/32" - DC jack

Use a step drill bit for the 15/32 holes

 

Install all the components and connect the pots and switches as shown in the photo.

White = Ground (GD), Orange = 3.3 volts (V+)

Left to right looking at inside:

Delay Ratio Switch (3-position micro-toggle, mounted sideways)
Pin 6 (3:4), Ground, Pin 9 (1:3)

Delay Pot (A5K)
V+, Pin 2 (DELAY), Ground

DC Power Jack
Tip [-], Shunt [N/C], Sleeve [+]

Depth Pot (B5K)
V+, Pin 5 (DEPTH), Ground

RCA Jack
(CK and GD on PCB)

Rate Pot (C5K)
Ground, Pin 3 (RATE), V+

Write Switch (2-position micro-toggle, mounted sideways)
Pin 16 (WR), Ground (GD), (bottom lug N/C)

Attach the remaining wires.

If you are using the Delaytion PCB, the connections are as follows:

Power [+] and [-] = 9 Volt DC Power Connection - attach [-] to the center lug of the DC Jack, and [+] to the other outside lug.

WR and GD = Write Switch and Ground - Connect to top 2 lugs of Write Switch

Depth, Rate, Delay - Connect to the center lug of their respective pots

1:3, 3:4 - Connect to the outer 2 lugs of the Delay Ratio Switch (center lug to ground)

Also connect the +V and GD header pins to the 3 pots, as described above.

Refer to the Board Layout Diagram and the Schematic for connection information.

 

NOTE: Delaytion and the Delay must share a common ground, therefore either connect the ring of the RCA jack to ground on both pedals, or use a daisy-chain type power connection

Dress it up and Turn it on!

Why modify the Ekko 616?

1) tap tempo timing with 3 delay ratios
2) create and recall four presets
3) wider control range for modulation with easy access controls

Modify your Carbon Copy to receive Delaytion's clock signal.

Why modify the Carbon Copy?

1) tap tempo timing with 3 delay ratios
2) create and recall four presets
3) no need to open up the pedal to change modulation ratio and depth
4) extended delay time
