The Diamond Pedals
Boost-EQ combines a very low-noise 16 dB discrete clean boost with an
innovative parametric EQ section. This EQ combines the powerful tilt
equalization control from the Diamond Compressor plus a new midrange
cut/boost control. This new parametric EQ section places the midrange
control right at the fulcrum of the spectral tilt EQ, giving a unique
and powerful tone shaping tool with just two knobs. For clean boost
purists, the EQ in/out switch allows removal of the EQ circuitry from
the signal path when not in use. Standard 9V battery or 9 to 18V
external -ve tip AC adapter operation.
Maintaining a clean signal within the boost-EQ,
the up to 16 dB signal boost (about a 6.5 time increase in a guitars
output voltage swing) can push most tube amp input stages well into
overdrive territory - but with a wider frequency range and more
responsive feel than standard diode clipping overdrive pedals. The
boost-EQ's simple goal is to enhance the natural drive character of a
guitar amp's tubes - anywhere from a light clean solo boost with 2-4 dB
of gain, to heavier tube breakup with higher boost gains. The versatile
tilt EQ gives spectral shifts that 'tilt' around a centre midrange
frequency ->> a midrange frequency range that itself can
be boosted or cut as desired with the MIDS control. Use the tilt
control to subtly lighten or darken your tone, then use the mids
control to add more solo bite by increasing mids, or tailor a gently
scooped clean rhythm tone by decreasing mids. This powerful parameteric
combination can generate a wide range of frequency response templates -
from an increasing slope telephone set response to smokey jazz
roll-offs to humbucker tones on single coils.
