GXSGTR OBViouS Boost/Overdrive Axess Electronics
The OBViouS™ Boost/Overdrive is a transparent and straightforward, lower gain pedal meant to push an already overdriven tube amplifier. The pedal’s stimulus was the beloved Marshall® JMP PLEXI and 1987/X family of amplifiers, which when pushed, benefit greatly from the design’s ability to sculpt and fine-tune, tightened and tailored, bass and treble frequencies for a hot- rodded transparent response. Even though the pedal impetus was a certain family of amps, the OBViouS™ Boost/Overdrive can be used to push other tube amplifiers, with equally great results. When pushing most tube amplifiers, including a beloved Marshall®, more than a single “boost control” is a great asset because human hearing is highly nonlinear, and guitar amplifiers are only slightly better in their linearity. In addition to the pedal’s obvious ability to garner transparent tones, it can also be used to drive your sound to the edge via its gain knob and three-position clip toggle switch. The pedal’s circuit design is a fusion of our buffers, line drivers, custom boosts, a popular dual buffer tuner mute and boost pedal that we designed for a MEGA company which is now part of a Gigantic corporation, and some other boost and overdrive pedals that we have long been fans of. Built-in Canada and designed for years of reliable use and performance. Whether on the road and on stage, in the studio, or in a bedroom, basement, or garage, our products continue to work day-in/day out, even after over 23+ years of solid use.
CONTROLS/CONNECTIONS
-
BASS is a three-position toggle switch; [i] least amount of bass [ii] mid-amount of bass [iii] most amount of bass.
-
CLIP is a three-position toggle switch; [i] clean boost i.e. no diode clipping [ii] and [iii] provide different diode clipping options. As the GAIN knob is turned clockwise, positions [ii] and [iii] introduce some amount of compression — with position [ii] clipping and compressing at lower signal levels than position [iii].
-
GAIN increases the output level of the boost/ overdrive circuit when turned clockwise.
-
Note: With the LEVEL set for unity and
the CLIP set to position [i], increasing the -
GAIN will result in a natural saturation of the circuit — the setting at which this begins to occur is input signal dependent.
-
LEVEL increases the overall output level of the pedal when turned clockwise — with unity being around 12 o’clock.
-
Note: For a clean boost, turn the GAIN full counter-clockwise and set the CLIP to position [i] — then turn the LEVEL knob clockwise as desired.
-
TREBLE increases the amount of treble when turned clockwise — with unity being just past 3 o’clock. LED is on (blue) when the boost/overdrive effect is active and off when it is bypassed.
-
STOMP SWITCH toggles the boost/overdrive effect on (blue LED on) and off (bypassed).
-
INPUT is a ¼” TS (tip-sleeve) input jack that accepts an instrument-level signal from a guitar, another effect pedal or a pedal/loop switcher…
-
OUTPUT is a ¼” TS (tip-sleeve) output jack that is meant to be connected to the input of an amplifier, another effect pedal or a pedal/loop switcher… 9VDC is the external power supply jack and it accepts a standard 2.1mm x 5.5mm male barrel plug from a 9VDC wall-wart power adapter or pedalboard power supply with a
-
NEGATIVE CENTER plug. Refer to the SPECIFICATIONS section for additional information.
-
⚠ ATTENTION ⚠ Do NOT connect any other DC Voltage or AC Voltage power supply to this jack, other than that specified in this section and in the SPECIFICATIONS section. Doing so will result in damage — voiding the warranty.
