Winner of the Premier Guitar Premier Gear award! The Mr O was created to reproduce the special and beloved sound of the original phase shifter pedal. Released in the early 1970's intending to replicate the sound of a Leslie rotary speaker, the phase shifter turned into a widely popular effect that influenced the sound and role of the electric guitar ever since. After many hours of careful listening, playing, and tweaking, we finally arrived at a design that earned its colors and has the elusive magic of this historic pedal. Mr O stays true to the original's six phase stages while packing much more inside of a smaller, pedalboard friendly footprint. Since the original had just three speed switches and no other adjustments, we gave the Mr O extra flexibility to satisfy the needs of a modern instrumentalist seeking the tones of this vintage classic.

CONTROLS:
-Speed controls the speed of the LFO. We carefully replicated the unique shape of the original's LFO waveform at various speeds.  Unlike a lot of modern phase and modulation designs, the shape of this wave changes slightly with speed adjustments. Balancing the amplitude and offset of the waveform at particular speed intervals are key to getting Mr-O to feel like the original. 
-Adjust Depth to achieve a more or less drastic phase shift. To the left, it can be quite subtle producing a slight phase shift to give your tone a bit of an evolving, "chewy" feel. To the right it becomes more intense and the unique waveform of the original becomes apparent. 
-The Color knob controls the amount of feedback regeneration, to add a bit more or less “whoosh” if desired. At the lower end, the tone is smooth and warm. Turning it up high creates sharper resonant peaks. 
-4/6 button to switch between the original six phase stages (up) OR decrease to four stages (down).

To most closely simulate the sound of the original, start with the Speed, Depth, and Color knobs pointing straight up to 12 o'clock with the switch UP in the six stage mode. You will now be closely emulating the sound of the original in the medium speed position. Adjusting Speed to the far left simulates the slow speed position, 2-3 o'clock simulating the fast position. We included a little extra to the far right for those who like to push the limits and like faster speeds in the vibrato realm. 

Additional Info/Power:
-True Bypass
-Standard center negative 9V DC supply (not included)
-Current draw: ~70mA
-The Mr O and MojoHandFX is in NO way sponsored, endorsed, or affiliated with Gibson or Maestro. MojoHandFX does not want to associate with or disrupt the legacy and goodwill of Gibson's Maestro mark.

Mixed Results - Sauberkugel Clean Ball Review
Color: Bag Petrol
I purchased the Sauberkugel Clean Ball in Teal to help keep my bags clean from dust, dirt, and crumbs, and while it had some positive aspects, I can only give it a moderate 3-star rating due to a few shortcomings. On the plus side, the concept of the sticky inside ball is ingenious and showed promise. It did manage to pick up some dust and small particles (including glitter) from my purse which was a relief. The teal color is cute and made it easier to spot in a bag. However, there were some limitations that affected its overall effectiveness. *It seemed to struggle with picking up certain types of debris, particularly larger crumbs, heavier dirt, and ever some larger glitter/confetti pieces. This inconsistency was a bit disappointing as I had hoped based on the ads for it to be much more effective. *Another major issue I encountered was the difficulty of opening and cleaning the ball. The design was supposed to make it relatively easy to open and clean (as the ads lead me to believe). However I was unable to get the ball unlatched - which made it quite challenging to clean fully. It was frustrating to wrestle with the ball and being unable open to clean it out fully. In summary, while the Sauberkugel Clean Ball had its merits and did manage to capture some unwanted particles, it fell short in terms of consistency and ease of use. The struggle to open and clean the ball was a significant drawback for me.

Great item, totally worth it.
Color: Black
I've used this for over a year now in my nice work purse to keep those tiny dirt particles from who-knows-where (you know the ones I mean!) from mysteriously getting in the bottom of of it. It rolls around easily in its plastic case either naturally (without getting goopy or leaky) or rolled by hand. Handiest thing I've ever bought to help keep my purse clean!

Simple and Effective Remote Organization
Color: Black, Size: Small
The Pros: Spacious Design: With five deep pockets, there is plenty of room to store everything from TV and soundbar remotes to reading glasses. Functional and Steady: It sits perfectly on a side table without tipping over. It does exactly what I hoped it would do by keeping all our remotes in one spot. Great Portability: It is lightweight enough to move around easily, which is helpful for keeping things organized while we are on the move. Clean Finish: The material looks professional and blends in well with the furniture without looking like a cheap plastic holder. The Cons: Pocket Depth: One thing to keep in mind is that the pockets are fairly deep. If you have very small remotes, they can slide down a bit far, making them slightly trickier to grab quickly. Bottom Line: This is a straightforward, no-fuss solution if you are tired of losing remotes in the couch cushions. It is well-made, looks good, and simply works. I would definitely recommend it to anyone looking to declutter their living space.
