The JV-1A (a.k.a.
Blue Bottle™
) is a limited edition
signature mid-boost pedal designed by
Effectrode
for guitarist John Verity (Argent). John wanted to
fatten-up the tone of the single coil pickups on his
‘Corona’ guitar and we came up with the idea of
basing his pedal on a vintage ‘Pultec’ inductor-
based tube equaliser circuit–the way we see it, if
you’re going to build a mid booster in pedal, why
not do it with some style! The JV-1A adds warm
and musical sounding mids that work to enrich the
natural harmonic character of the guitar
and
there’s
also 18dB of all-tube gain on tap allowing the
Blue
Bottle
to push a tube amp into generating a
beautiful, singing, bluesy overdrive.
Audiophile grade components and silver solder are
utilised throughout the circuit along with precision,
low noise, metal-film resistors, stellar-quality
polyester coupling capacitors and ground-plane
layout. The result of all this attention to detail is a
mid-boost pedal with a full-bodied, rich and
addictive lead tone for solo playing–John Verity
seldom turns the JV-1A off!
Thank you for trusting
Effectrode
to be your effects
company . We wish you many years of musical
enjoyment from this hand-built, all-tube pedal.

The JV-1A signal path is based on
a
Sylvania
6111
N.O.S.
subminiature twin triode pencil
tube. These tiny tubes were
specially developed by
Sylvania
Electric
in the 1940s for military
and aerospace applications to
meet
their
stringent
Mil-E-1
specifications for reliability and
long service life under conditions of
severe shock, vibration (20,000G!),
high temperature and high altitude.
Sylvania
subminiature
tubes
represent the absolute pinnacle of thermionic
technology and are unquestionably the finest tubes
ever made by any company , ever–we will certainly
never see the likes of them again.
