The PastFx Chorus Ensemble Mini (CEM) is based upon the Holy Grail of Chorus pedals, The BOSS® CE-1. First released in 1976 it became famous for lush Chorus and Leslie effect Vibrato.

The PastFx Chorus Ensemble MN3007 Mini (CE-7 Mini) is a modified PastFx Chorus Ensemble Mini ,using the less obsolete NOS MN3007 BBD.

The CE-7 Mini uses the same PCB as the Mini, is almost identical with components and is attractively priced.

The CE-7 Mini operates off the same bipolar voltages, the exact same preamp section, and incorporates both switchable Buffer Mod and built in Depth Mod.

incorporates the “Noise Killer” circuitry
Same unique Preamp stage
Normal / effect footswitch
Vibrato / Chorus toggle switch
Triangle Wave LFO – Chorus
Sinewave LFO - Vibrato
Not True Bypass (Jfet switching as original )
Red LED Peak Level Indicator visual feedback of input sensitivity
High / Low Input sensitivity changeover switch
Blue LFO rate LED, visual indication of LFO Rate
Stereo/ Mono Outputs. In a Stereo setup, wet signal is directed to the Stereo jack and Dry to the Mono output jack.
Vibrato controls are Depth & Rate
Chorus is controlled by Intensity knob (which controls both rate and depth)
When effect is bypassed the LFO LED indicator remains on without flashing
Pedalboard friendly, uses minimal real estate and operates off industry standard (9VDC negative tip )
The CEM also incorporates up to 2 extra popular modifications that many owners of the original unit would use.
Depth Mod

This mod is popular for those who were wanting more control over their chorus effect.
The Vibrato Depth knob now controls the Depth of both the Chorus & Vibrato. The Stock depth setting of the Chorus can still be achieved by turning the Vibrato Depth knob fully clockwise.
Buffer Mod

Many owners of the original noticed that when selecting the high on the input sensitivity switch that some of the high frequencies of their signal was lost. This was a desirable outcome for some. To remedy this, some users would place a buffer before the BOSS® CE-1 to restore the high frequencies. The CED comes with an inbuilt buffer circuit which can be added or removed as desired.
Note: When clipping the signal heavily by having the Level control on high, it can give various responses based on what type of amp is being played through.
On some amps it can almost sound like a fuzz, and on others a more traditional crunch sound! This is the same experience with the original.
