PQ-3B (Bass Parametric Equalizer) w/Original Box

Effect Information

“Three knobs
representing three EQ bands: Low, Mid and High, with the outer casing of
the knob controlling the frequency and a smaller internal knob the
level. There is a fourth knob to control the overall volume +/- 18db.
Pretty self explanatory once you know what you’re doing.”

“Very
quiet for an EQ, with a slight hiss when the “high” volume knob is
turned up fully. Although it’s designated a Bass EQ, it can work on any
electric instrument as its frequency range is from 25Hz to 16kHz.”

“Whether
you use a solid state or tube amp this pedal can be used to “tune” your
sound for each piece of gear and for each room/venue. Because the
frequency range is so wide, it can be used effectively for guitar, bass,
vocals, and even a DJ setup. This is one of my favorites.”

“You
can use it as a bass boost, a solo (mids) boost, a treble boost, cut
some bass from a poorly EQed fuzz, a simple volume boost to drive your
amp a little harder, maybe even a kill switch. Unless you must have more
than 18dbs of boost, I’d choose this over other “clean boosts” like the
MXR Micro Amp, Zvex SHO etc. Way more versatility at a fraction of the
cost.”

“Pretty easy to use as long as you know what a parametric
equalizer does. It controls bass, mid-range, and treble with a range of
25 Hz to 16 kHz. This is close to the extent of human hearing. Each
parameter and the overall volume is adjustable from +/-18 dB.”

“Tone
can be stretched in ridiculous ways with this device. Through extreme
knob turning there is not a bit of background noise. The +/-18 dB range
is pretty extreme, but it is indeed that flexible. On most parametric
and graphic equalizers, it is difficult to create convincing sounds when
you stretch a knob or slider beyond +/-12 dB. That flexibility is
available with this effect. This pedal is awesome as a customizable
clean boost — that is where the +/-18 dB range comes in handy.”

“Boss
PQ-3B Bass Parametric Equalizer pedal. 18dB of boost (the most of any
Boss EQ pedal) or cut across low, middle and high bands. Level and
frequency controls for each band for dialing your sound. Overall level
control as well.”
