Boss TR-2
Tremolo
“C4 Mod”
Story time: I once performed this
modification for a Nashville studio
musician, transforming the humble
Boss TR-2 into, and I quote, “the best
tremolo [he’s] ever heard.” Now that I
have your attention, users who bought
a Boss TR-2 on the second-hand
market might notice a slight volume
drop when engaging. This volume drop
also begets a distinctive “mush” in the
modulation which can drive tremoloheavy players bananas. For those guys
and gals playing low-budget surf rock,
the older TR-2s can really take some
curl out of the waves. This, the C4 mod
(which is in no way related to plastic
explosives) reinstalls some of the pep
that’s siphoned out of the modulation,
as well as restores that precious volume.
What you’ll need:
Screwdriver, wire cutters or nail clippers
The fix:
Remove the back from
the pedal, and remove the board. Look
at the component side, and hunt around
for a capacitor (looks like a Chicklet)
marked “C4.” Using the clippers,
remove this capacitor. No, really, that’s
it. For fun, you can change the color of
the LED (just remove the stock LED and
replace it with a different-colored 3mm
LED) so people can know you modded
it. Of course, that is totally optional.
