If you ordered either V-drum Reburb Kit for the Head Trigger or the Head & Rim Trigger, you are about to restore its performance to when it was brand new.
Does your Roland V-drum look like this (PD-120)?
It will look like this after refurbishment/cleaning & new
Piezo/Cone Trigger parts.
you’ve got a newer V-drum design, don’t worry if your drum looks different
inside, piezo’s locations are different, etc.
Inner designs have changed, but the parts and their
replacement/refurbishment haven’t changed, so everything in these instructions
apply to ALL V-drums
Aside from upgrading the key triggering components, the
other steps you can take in completely refurbishing your V-drum are:
A thorough cleaning inside and out
Replacing a worn/damaged 2-ply mesh head with
Either a Roland OEM mesh head OR a 3-ply mesh head available through my
Cleaning a dirty white mesh head with my
Stardust cleaning product available through my website.
Replacing a worn/damaged Rubber Rim Protector with
my Rim Condom product available through my website.
replace the piezo/cone triggering components, follow these 7-steps:
Remove mesh head and take note of the how
piezo(s) wires are connected to the circuit board. Which wire goes to the white center &
which wire to the brass outer ring of the piezo – mark them or take note.
Using a wire cutter, snip old piezo wires near
the piezo(s), leaving original soldered wiring intact. There is no good reason to re-solder wires to
the circuit board.
With a flat head screwdriver, putty knife or a
safe razor blade, pry off the old piezo(s) and remove residual foam tape off of
surface. Thoroughly clean surface to
prepare for new piezo(s) adhesion.
Feed the centered head piezo new wiring through
the platform small hole (if available) before connecting to old wires like in
photos above. Prepare old wire leads and new piezo wiring for splicing with
1/2” of bare, twisted wire ends. You can
shorten the combined new/old wire if you desire as there is plenty to complete
the splice. Begin splicing new and old
wire leads together with tight twists and complete each connection using the
(grey colored) twist-on wire connects provided.
Some use shrink tube, your choice.
Peel and stick new piezo(s) onto original cleaned
location. Tuck/secure the spliced wires
to conceal as best you can.
For the head piezo/cone - height is to be
properly set, 1/16” or 2-3mm above the bearing edge plane. Verify with a straight edge ruler across the
drums bearing edge that you have the cone tip protruding above the bearing edge
plane, approximately 1/16” or 2-3mm - this means the cone tip will be pressed
into the bottom of the mesh head. Once
you confirm this proper cone tip height over the bearing edge plane, then peel
and permanently stick the cone into place, being careful to center it on the
piezo. Press and hold cone to ensure a solid
adhesion. Most Roland trigger platforms
have some micro vertical adjustment screws, up/down, and this may need to be tweaked
to attain the cone tip position of 1/16” or 2-3mm above the bearing edge plane.
Re-install mesh head, the upgrade is complete and
it is time to get back to playing – Rock-on!!
