Stereo Chorus PX65


PX65 Chorus





PastFx Stereo Chorus PX65 is a faithful reincarnation of the beloved DOD FX65 Stereo Chorus,

which is rumoured to have been used by John Frusciante of the Red Hot Chili Peppers during the Blood Sugar Sex Magic album era.

It also includes extra features and tonal options allowing more possibilities from this classic circuit.


  • True Bypass / stereo outputs
  • Speed, Delay Time, & Depth controls now all have increased ranges. The Modulation rate can now produce a significantly slower speed. A red LFO LED indicator for visual speed display has been included.
  • The Delay Time control can also access shorter and longer delay times than of all the DOD FX65 and FX62 models. The Depth control can also access more extreme “seasick” modulation intensities.
  • The original FX65 and FX62 (Bass Model) were usually populated on the same FX65 PCB. We included 2 internal slide micro switches that enable switching between either the FX62 or FX65 circuits. (selecting any combination of slide switches will not damage the pedal)
  • Feedback from some FX62 users, expressed the desire to have a volume control as some felt the effect was not always at unity with their bypass signal. A Level control has been added to solve this issue. The Stock core level can still be achieved by turning the Level knob fully CCW. This becomes necessary when engaging the Vibrato mode. (see below)
  • A Blend control has also been included. This limits the amount of Wet / Modulated signal that combines with the dry signal. Again the stock circuit can simply be achieved by turning the Blend knob fully CW. Sometimes the reduction of the wet signal can produce a slightly perceived volume drop. The Level control can compensate for this, bringing the chorus signal back to unity gain.
  • Also not included in the original is a Vibrato feature. A pushbutton Vibrato switch can cut the dry signal to create this effect. When engaged, the lower red on/off led indicator will change to blue indicating this mode. The Blend knob will need to be fully CW in this setting. In this mode the Level control will need to be adjusted to return the lower signal level to unity gain.
  • The pedal now runs of the standard 9V DC  (Maximum 12VDC) Neg tip “Boss style” power supply jack. The uncommon DOD style powering connector is no longer needed.
  • Lastly, thanks to observing the creativity of how Andy Martin (Andy Demos) uses his Modded DODFX65, we have included the Dave / Andy switch. Dave Mode (Named after the great Dave Simpson) is the default Dod FX65 setting.
  • Switching to “Andy” mode, the pedal can now access the stereo output “out of phase” tones without having to swap cables between the mono and stereo output jacks.
  • A new Regen push button option has also been added. This feature of introducing a small amount of feedback (similar to a flanger circuit) allows a more intense “Andy” mode.The level of feedback can be adjusted via an internal trimpot (located on the middle RHS ofthe PCB) . Increasing the level control can magnify the amount of feedback, thereforeadjusting both to obtain the desired amount is required.The Regen function is only availablein “Andy” mode! When in this mode the top red led will alternate flashing blue.
  • When in this mode, faux “Through-Zero Flanging” tones can be achieved when turning the Speed control to very slow and having the delay time control between 0-25%



Faithful Dod Fx65 circuit with larger range of speed, delay time & depth.
Includes a Red LFO led for speed visual indication.
Level control allows to boost signal in Vibrato mode ( stock FX65 CCW).

Blend knob to dial back the wet signal.
