$199 is your absolute final/total here for the the Fredric Effects Utility Perkolator MKII pedal.

This Utility Perkolator is Fredric's latest version of the highly sought-after Harmonic Percolator from the 1970s, made famous by Steve Albini of Shellac.

This MKII version pedal comes in a new triangular wedge enclosure and has some new features added as well. They added a ring modulator switch, for octavey/splattery overtones. This ring circuit is closely related to the vintage Dan Armstrong Green Ringer effect. Also, on the inside of the pedal, you will find 2 dip switches on the circuit board, to remove the low pass filter if desired (see "CONTROLS" below for details).

Before we get way into the Utility Perkolator MKII, the next 2 paragraphs simplify the difference between the Fredric Effects Harmonic Percolator and their Utility Perkolator:

Fredric Effects Harmonic Percolator - this clone is the 100% vintage correct circuit, with the hard-to-find, new old-stock vintage components. It has the unpredictability of the vintage Harmonic Percolator on which it is based, with a raucous edge to the sound, and a fizzy decay note.
 
Fredric Effects Utility Perkolator - this is the result of experimenting with the Harmonic Percolator circuit for a few years. It uses lower leakage, old stock USSR germanium transistors, and incorporates a very subtle low pass filter, which takes the fizz out of the decay and makes it generally a "better behaved" Harmonic Percolator. However, it is still capable of some great, full-on fuzz sounds!

 

The Harmonic Percolator is a simple, yet fascinating circuit which readily lends itself to some tweaking. Fredric Effects already builds a faithfully vintage version of the Harmonic Percolator, however their Utility Perkolator MKII takes this circuit in another direction.

Using higher gain, lower leakage Russian Germanium transistors, and a low pass filter which only removes the high-end hisses and glitches associated with the Harmonic Percolator, the Utility Perkolator MKII has a considerably lower noise floor, and more predictable note decay. The result is a tighter and more controllable effect which is still capable of producing the classic Harmonic Percolator sound.

Reviews from our customers at Reverb:

 


CONTROLS:

Harmonics:
Controls the gain of the circuit.

Balance:
Controls the overall volume of the effect.

Si-Ge Switch:
Selects 3 diode clipping options.
Up - Silicon clipping for a smoother sound.
Down - Germanium clipping (like the original Harmonic Percolator) for a grittier sound.
Middle - No clipping, for a more open and less "fuzz" sound.
The overall volume will be higher with no signal clipping selected.

New for Version 2...
Ring Switch:

This engages a ring modulator switch, for octavey/splattery overtones. This ring circuit is closely related to the vintage Dan Armstrong Green Ringer effect.

Dip Switches on the circuit board inside the pedal:
R8 bypass, NR on - A simple, yet subtle low pass filter. By default (see photo of the inside), these switches are in the positions OFF, ON = low pass filter engaged. To disengage the filter, you can set these to ON, OFF.

Heavy duty brackets!
Size: 8 Inch, Color: Gold, Size: 8 Inch, Color: Gold
These brackets are heavy duty and came with the correct hardware. They were easy to install, the two holes were so helpful to know where to mark them. I think because they’re heavy duty you can place a good amount of weight on your shelves. The only thing I wasn’t happy with is that 4/69 of shelves, the paint was chipping but it was the perfect gold color.

Don't hesitate - Great product!
Size: 12 Inch, Color: Black
Superior quality at an unbelievable savings over local retailers. Hardware for hanging included the cheaper plastic lags yet they also included the heavy duty lags, so no tapping in to our supply. Thank you for a great product
