80/A Flanger


80A Flanger

Currently we have only a limited number of pedals available. This is due to the small amount of Vintage Bucket Brigade Devices we have been able to source.

              I would also like to acknowledge "Scruffie" for his invaluable assistance and counsel on this and several other PastFx designs.




The 80/A Flanger is based upon a venerable late 70’s, early 80’s discontinued analog flanger pedal famously utilised by numerous musicians, including the likes of master guitarists Pat Travers and Paul Gilbert. It uses an obsolete high voltage 512 stage Bucket Brigade Device with  extra features and functions all in a small Pedal Board Friendly sized enclosure.

From subtle modulation, to soaring jet woosh, to metallic clang and out-of-this-world warble, and everything in between– the 80/A delivers a vintage-correct reimagining and expansion of the original from which it was inspired.

The pedal is capable of a very broad range in terms of LFO/Speed rate (up to approximately 30 sec), and delay time (0.39ms-14ms)

Furthermore, the 80/A includes a very useful blend control, which allows the wet modulated signal to be reduced allowing a more subtle effect. New Red and Blue LFO rate indicators now allow a visual confirmation of the speed of the effect.



Manual - controls the fixed delay time of the effect. (When a stereo cable is inserted into the Control jack, the manual control will no longer function.)

Range - controls whether the speed control (automatic) or Manual control (fixed) controls the Delay time. FCW = 100% speed control. FCCW = Fixed (Matrix style) 12 oclock is a blend of both

Speed – controls the automatic rate of the LFO (visually displayed via Blue/Red LED)

Blend – New control which restricts the amount of modulated / wet signal mixing with the dry signal. Fully Clockwise is stock setting.(reducing the blend does not reduce the feedback)

Threshold - controls the sensitivity of the Noise Gate circuit which is determined by the intensity of the instruments attack. Fully clockwise minimises this feature. With careful CCW adjustment, the Threshold control can allow an envelope style flange occurring pending the attack and amplitude of the signal fed.

Enhance - Also known as color/feedback/regen, controls the amount of signal regenerated back into the front end of the circuit. This allows the flanger to create a more intense effect.

Level – Allows for output volume adjustment of overall effect

Harmonics – Blue LED = Negative Feedback (hollow tubular sound), Red LED = Positive feedback (fuller sound)

Control - expression pedal jack allowing the Manual control to be controlled externally using a 10K – 100K potentiometer.

(Ring - Pot pin 1, Sleeve - Pot pin 2, Tip - Pot pin 3)

Technical Specs:

  • Matsushita / Panasonic 512-stage Bucket Brigade Device
  • Does NOT use  low voltage BBD Chip, resulting in higher headroom when the effect is engaged
  • True bypass operation
  • 18V DC centre negative power supply requirements; no battery option available
  • Dimensions: 112 x 60 x 31mm / 4.4" x 2.36" x 1.22" (enclosure only)
  • Current draw: 35 mA
  • There are no internal adjustable trimpots. Changing their position will result in a non functioning pedal.
  • Please only use high quality 18VDC regulated power supply with Boss style Negative tip.
  • Cheap switchmode power supplies, will guarantee noise issues and performance issues!


We recommend but not limited to:
• Voodoo Lab Pedal Power ® 2 Plus etc.
• Cioks DC7/4/8/10/SOL.
• Walrus Audio Phoenix.
• T-Rex® Chameleon Fuel Tank
• Truetone 1 Spot PRO CS7/12 only
• Gigrig Generator
• Eventide PowerMax / Mini
• Strymon Zuma/Zuma R300/Ojai R30
• Donner® DP-4 ISO 8 PLUS
• Fender Engine Room LVL8 / LVL12
• Mosky®C8 Power Station
• Dunlop ECB004 18VDC*
PLEASE NOTE: * Dunlop ECB004 18VDC is an economical switchmode power supply that may work however,
in a complex pedal board setup switchmode supply noise may occur.
It is recommended to use a high quality power supply (see above) to avoid such issues.
