WARM ANALOG PHASE SHIFTER & GAIN DEVICE

Pronounced "mountains", mntns is a variable-stage phaser with vibrato and gain modes.  Knobs control rate and amount of gain, and toggles allow 7 positions of options!


INSPIRATION:  We love the clean, high headroom phasers from the 70s and have created a circuit that honors the sound of the originals, while utilizing modern technology and adding features for today's players.


CIRCUIT SCIENCE:  At its core, mntns is an OTA-based analog phase shifter.  The knobs control LFO rate (phase speed) and a JFET op amp gain stage.  There are two stages of filters available- 2 for a milder warble and 4 for a rich, warm swirl.  The feedback (FB) toggle when engaged (to the left) introduces output signal to the input, sometimes called regeneration.  This results in a more intense, wider sweep of the LFO and phaser effect.  The mode toggle has 3 positions- G (Gain-only mode), P (Phaser mode), and V (Vibe).  The feature toggles and unique gain structure control allow you to dial in several classic sounds, as well as new sonic explorations.


SOUND:  mntns delivers clean, warm phaser tones suitable for a wide range of musical tastes. 

-Dial in the Gain control to set mntns at unity or boost the signal if desired.  You can also simulate grittier JFET phasers by turning the Gain control all the way up.  The Rate control will vary in function depending on the toggle settings and can achieve anything from very slow sweeps to speedy, robotic ray guns.

-The feedback works best in the Phaser mode, sounding more intense for 4 stages and curiously more vocal in 2 stages.

-The Vibe mode allows true pitch vibrato and works best at faster rates.  Try 4 stages for deeper pitch bending and 2 stages for a subtle shimmering effect.

-The combination of the transistor input stage and the op amp output stage can be isolated in the Gain-only mode.  This creates a unique gain structure that provides an organic boost with a touch of breakup when cranked.

Note:  The FB switch when on will mostly nullify the Vibe and Gain modes, rendering them slightly different phase shift tones.  

Quick settings:  Here are some ideas to get started!

  • Classic 70s sound:  FB off, 4 stages, Phaser mode, set Rate to taste, adjust Gain to unity
  • Dramatic tone contrast:  FB on, 2 stages, Phaser mode, set Rate slow, Gain to taste
  • Polite robot:  FB off, 4 stages, Vibe mode, Rate all the way up, Gain to taste

Austere design, esoteric nomenclature.

Skip the introductions and go right to the narrative
Let's face it. Most of the history I read is written by white people. Some things need to be read in the "first person" and this is one of them. Not only is it a landmark book (not just for it's time but for all time), it is still easy to read, believable, compassionate to all (including slave owners) and completely gripping. It is not too brutally descriptive to be disturbing to any older kids or teens I know, and it is a patient, instructive and compelling story that I believe could still be a powerful, memorable and life changing read for anyone. Personal Note: I went to Maryland public schools in the 70's and early 80's. This was not on my required reading list. I wish it had been, but then maybe I would have hated it. The story of Frederick Douglas is to me overwhelming. The indictment of Southern Christianity is also particularly grievous. I do feel like I'm beginning to get a sense of the longtime North - South cultural divide as a matter of regional . . . religious . . . and economic ... pride. Misc Notes: 1. Brer Rabbit - in the intro to my book - Robert O'Meally mentions Brer Rabbit and Disney's now banned (and well censored) in the USA "Song Of The South" movie (think "Zip-A-De-Do-Da") - I don't have any wisdom on this but Brer Rabbit is a vaguely forbidden character in our country, as is Bugs Bunny, who the writer indentifies as a modern day Brer Rabbit. I always liked Bugs Bunny, but you don't see these cartoons around. I have an older African American friend who asked me if I could find a copy of "Song of the South" which he had fond memories of watching in the movie theater as a kid. Well I couldn't . . . 2. In my appendix, there is mention of pro slavery arguements of the 1840's. One is to the effect of "Slavery itself doesn't hurt slaves . . . its the abuse of slavery by slaveholders that hurts slaves." Hmmm, that sounds familiar . . .

An essential American autobiography
As the title implies, this short work is the narrative of Frederick Douglass, an escaped slave. He wrote it by himself, a significant fact in that his prose is so eloquent and his pathos so powerful that it seems impossible for a former slave to have composed it. In this short autobiography, Douglass recounts his life as a slave, and details some of the horrors and atrocities perpetuated on slaves by their fiendish overseers, most of whom Douglass portrays as downright evil. More than just a narrative of his life, Douglass also gives an account of how the desire to be free grew and began to burn within his bosom, and how he grew to hate that horrible institution. Above all, this is a story of a slave learning that he is, in fact, a human being. The significance of this book cannot be overestimated. In it, Douglass effectively dispels a number of popular myths about slaves and slaveholders, and forever changes the way the reader (especially one who lived while slavery still existed) looks at slavery. The theme of this book is very simple: slavery is wrong. It is evil, it is cruel, and, despite what many people thought at the time, the slaves know how cruel it is. Douglass cites several examples of the horrible treatment slaves received, one of them being separation of families. "It is a common custom...to part children from their mothers at a very early age" So it was with Douglass and his own mother. Douglass writes in a very eloquent style, and this contributes to the power of this work. Many people who thought blacks were inferior in intelligence were shown to be sadly mistaken with the coming of Frederick Douglass, a man both educated and refined. It may be said that the book is not entirely fair, for it is decidedly anti-slavery, but it is undoubtedly true for most cases nonetheless. Most of the overseers in Douglass's narrative are demonic and sadistic, but when a good overseer comes along (such as Freeland), he is fair in his treatment of him. One can imagine the fuel this book gave to the abolitionist fire, and it is not difficult to see why Douglass had such an impact on both North and South. This is, in my opinion, a definitive work, in that it shows the horrible institution of slavery in all its barbaric nature, and does it from a firsthand point of view, that of a former slave. This book was a tremendous contribution, both for the light it shed on slavery in general, and for proving that blacks were not intellectually inferior by nature, but instead were "transformed into...brute[s]" at the hands of their overseers. This is a great book, essential for anyone wanting to study the Civil War era or wanting to gain a firmer understanding of slavery.

This man's ability to describe the various monstrosities encountered throughout his journey in such a beautiful, articulate
I found this book, though historic, to be a modern marvel. I find not only the man himself but even more so the writings of Frederick Douglass to be totally FASCINATING! This man's ability to describe the various monstrosities encountered throughout his journey in such a beautiful, articulate, and eloquent way is utterly GENIUS! In reading this timeless masterpiece I discovered that this man bears the unmatched, undisputed spirit of a champion; the undying essence of a true warrior that I'm sure would resonate to any and every reader who would be so bold as to take a glance at the greatness that lies between the pages of this work of genius. This man's profound desire to acquire knowledge and educate himself by whatever means necessary exudes a ground shaking, bone rattling determination as I have scarcely; if at all, ever heard of. Frederick Douglass is to me the epitome of class and integrity and can serve as a role model and an inspiration to anyone in search of an incentive to better themselves, even or ESPECIALLY in the face of adversity. In this BRILLIANT account of his heroic journey from slavery to freedom he bestows a wisdom; a very keen insight, and he embodies an honor, the likes of which I have never seen in ANY other writer. I HIGHLY recommend this book to ANYBODY who is in search of inspiration or just a GREAT read!

Simply the best narrative I have read...
As society moves about, the slavery of the past remains alive and well. "Sweep it under the rug and do not bring it up" is the mindset of many. This type of suppression is often brought about because of the known guilt of an unfair past. American slavery has deep roots, reading the life of Fredrick Douglass, will help unveil some of the true history of America. At one point in the book Douglass realized he had past the time of being an indentured servant and knew that being a slave for life was his fate. He was treated with little if no respect. Douglass described Mr. Severe, one of his "masters", as a man who would whip a slave for almost no reason at all (22). Dougless illustrated that Mr. Severe had no respect for his slaves, but treated them as if they were not human. Many people may think that Douglass story was the exception, but that's not the case. Many times through out the book Douglass spoke of other slave's punishment as far worse than his own. He even recorded the murder of two slaves in Talbot, Maryland and stated that the slave owner never paid for the crime (31-33). This type of abuse almost seems unfathomable, but it's reality. Studying the origins of slavery can allow us to see the disgusting progression of the enslavement of human life and stripping of human character. Douglass' narrative provides the reader with a glimpse into the life of a slave. The emotional state of Douglass was strong, considering the abuse that he underwent during his life. The narrative of Fredrick Douglass is a superb read for anyone wanting to get a first hand understanding of the life of an American slave.
