Welcome to the Rainbow Machine, in all its synthetic glory! This one is for experimenters, adventurists and noisemakers. Totally not for purists and/or tone hounds, there are no “natural sounds” that will come from this box. It takes modern DSP and uses it as a tool of future past to create real time pitch shifting using digital oscillators. The sound is much different than most modern day pitch shifting devices. It was imagineered to be wild and out of control and slightly imperfect while still tracking up and down the guitar neck without glitching out. A cold digital beast made to pretend it has feelings. It will do basic polyphonic harmonies from a 4th down through a 3rd up and every atonal pitch in between. You may add in an accompanying octave of the harmony by bringing up the Secondary function control. You can take it way beyond and open up your third eye by bringing in the Magic. The Magic is the heart of the Rainbow Machine. In conjunction with the Tracking control, the Magic creates wild pitch take offs and descents, chaos chorusing, shrieks, pixie trails and wealth of other general mayhem inducing noises. The pitch can be controlled by an external expression pedal for extra fun! The Rainbow Machine can be used on bass, keys, vocals or anything else you can dream up! This device has become a main stay of so many studios and touring musicians that we have lost count! All digital wet signal with an all analog dry signal, true bypass switching and handmade one at a time by warm blooded human beans in the swamps of Akron, Ohio.

Controls

Pitch: This controls the pitch of the harmony. All the way counterclockwise is a 4th down, all the way clockwise is a 3rd up. The middle position is unison. The pitch can be controlled by an expression pedal as well.

Exp Jack: This is an expression pedal control jack for the pitch. The Pitch control is defeated when an expression pedal is inserted.

Primary: This controls the volume of the Primary pitch-shifted signal. Unity gain is at about 2 o’clock, anything above will boost the signal.

Secondary: This controls the volume of the secondary pitch-shifted signal. The Secondary controls the octave up/down from the primary pitch. At the noon position the Secondary is not present at all. However, turning the knob counterclockwise from noon yields an octave below, whereas turning clockwise yields an octave above and everything in between. Unity gain is at about 2 o’clock, anything above will boost the signal.

Tracking: This controls the amount of lag time between the direct dry signal and the shifted wet signal. The pitch-shifted signal will track right on the dry signal when this control is all the way clockwise. It will start to lag behind the more it is reduced. This function is especially useful when the “Magic” is engaged.

Magic: This adjusts the “weirdness” of the effect. The end result is a wide variety of wild effects depending on where the other controls are set. The magic control will only work if the magic switch is engaged and the primary and/or secondary are in use. (Technically, it’s a regeneration control that creates aliasing between a mix of the primary and secondary functions feeding back against each other.)

Tone: All the way clockwise is full signal, turn counterclockwise to soften the highs.

Power 

standard 9 volt DC power supply with a 2.1mm negative center barrel.

Absolutely Worth It!
Size: Standard
I've been using the Schenley Steam Mop for a few weeks now, and I'm genuinely impressed with how well it cleans. The steam heats up very quickly, and I love that I can clean my floors without using harsh chemicals. It easily removed dirt and sticky spots from my tile floors and left them looking fresh and sanitized. Very happy with the purchase!

CORD is TOOOOOO SHORT!
Size: Compact
Update: Schenley Customer Service paid attention to my review. While they obviously couldn't fix the short cord, they did send extra pads. I appreciate this effort. I will need to use an extension cord, when using. Not sure how Schenley could rectify- maybe with a credit towards the purchase of their upgraded model, with longer cord? This Steam Mop does a great job. It leaves no water residue after you've mopped. This is a change from a previous steamer I owned. If this mop's cord was longer, flexible, and containable with the unit, I would have given this five starts. Unfortunately, the cord is extremely short, making it impossible to do a downstairs using one plug socket. You have to turn the unit off, unplug, and then plug in to another socket. This happens multiple times during the process. The unit heats up quickly, but we shouldn't have to constantly plug/unplug turn off/turn on the unit in order to accomplish the job. Schenley needs to make a better, longer cord for this unit. Then, I'll give it five stars.

Love them!
Color: BlackNatural
This knife set exceeded my expectations! The knives are extremely sharp right out of the box and cut through meats, vegetables, and bread with ease. The German high carbon stainless steel feels durable and high quality, and the handles are comfortable to grip while cooking. I also really like the sleek black knife block — it looks modern and stylish on the counter without taking up too much space. Having 14 pieces included makes this a great complete set for everyday cooking. So far the knives have held their edge well and clean up easily. Excellent value for the price and a great addition to any kitchen!

Love the design of the container that the knife stand up in. The knives are super sturdy and sharp.
Color: Peach Pink
They are very nice and they’re very sharp. I surprisingly found them in pink to match my kitchen, which is great. They’re very easy to use and it looks like they will last quite a while.
