To Modify the Malekko Ekko 616 MK II Analog Delay
tutorial demonstrates how to modify the Malekko Ekko 616
MK II* Analog Delay so that it receives the clock signal from
PedalSync's analog delay control station, which features tap tempo,
modulation, and four program storage.
modify the Ekko 616?
tap tempo timing with 3 delay ratios
2) create and recall four presets
3) wider control range for modulation with easy access controls
Delaytion can control most analog delays based on the Panasonic
MN3205 and MN3208 chips and their clones. This includes the MXR
Carbon Copy and Build Your Own Clone's Analog Delay.

DO NOT BLAME US IF YOU RUIN YOUR EKKO 616 TRYING TO PERFORM THIS MODIFICATION!!!
we have not yet modified a first edition Ekko 616,
so if your Ekko does not have the blue circuit
board, do not use this tutorial!
you would rather have Molten Voltage perform this modification

the four (4) bottom screws. Use the right size Philips screwdriver,
as they are tight!
and remove C42 and R42.
not desolder any other parts or touch any trimpots!
EXTREMELY CAREFUL NOT TO DESOLDER OR DAMAGE ANY OTHER PARTS. BE ALSO
CAREFUL OF THE CAPACITORS STICKING UP OFF THE CIRCUIT BOARD, AS THEY
CAN EASILY BE BROKEN OFF.
the audio jacks nuts with an 11mm wrench.
the knobs with a flat head screwdriver, then remove the pot nuts with
a 10mm wrench.
the pot washers.
the switch nut with a 14mm wrench, and remove the washer.
carefully apply pressure to different parts of the top of the pedal.
Press the switch and the pots alternately to slowly remove it from
the enclosure. IT IS VERY TIGHT SO BE CAREFUL
NOT TO BREAK ANYTHING!
the audio jacks past their holes is the hardest part and sometimes
requires apply a bit of pressure in the jack, but NOT ON THE PLASTIC
THREADS or the metal tabs.
this is a VERY tricky dissembly.

a 3 inch jumper wire to pin 7 of the 3102 chip. The pins are sticking
through the PCB - (see photo). Pin 7 is the second one from
the left on the bottom row of 4 pins. Connect the other end of the
center lug of the RCA jack.
With the Ekko, there is no need to ground the RCA jack as the aluminum
enclosure is grounded and the RCA jack is metal.
the jumper wire around the circuit board by the screw hole as shown
in the photo.
re-assembling, compress the little ground springs (see photo) with
a flathead screwdriver to get the inside the enclosure.
sure the LEDs are straight and tall as they can be and put the PCB
touching the chips, trimpots, and other components on the circuit
take some force, but be sure not to hit any trimpots or capacitors
and try to only press where there are not parts.

everything back together.
the knobs back on without pushing them all the way down - they need
a bit of room to turn properly. Tighten snug, but do not overtighten.
not overtighten the audio jacks!
everything snug, but not overtight - the parts can break.
