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.

Magnets holding the back piece fell out. Other than that it works as advertised.

Really Cool
This is actually a well made portafilter. It was such a good idea to be able to have a nice WDT tool built in that doesn’t take up some extra counter space or anything. It minimizes clutter and just was a good idea so you always have it handy. Definitely would recommend.

Fine basket, lousy magnets: Look elsewhere
Build is nice, solid and the baskets fit snuggly without being too hard to remove. The WDT tool works well and came with a surfeit of needles. HOWEVER The tiny magnets holding the WDT in the handle aren’t glued in place and now come FLYING out when the tool is removed. One or two pull free and then shoot across the unit, pulling others out and ending up somewhere in the kitchen. Fortunately (because they’re REALLY small), they form a small column making it somewhat easier to track down. But it’s such a nuisance I now leave the tool out, so there’s a small dangerous hedgehog of verrrry thin needles in my kitchen we need to work around. Sub-optimal, sorta defeats the purpose of in-handle tool.

***Twist the WDT tool to remove dont try to just pull, or use your finger nails A slight twist will break the magnetic bond and the tool just comes out of the handle*** i got this to get away chemicals, hot acidic coffee possibly leaching plastic and aluminum that the stock portifilter is made from. This seems like a nice stainless by the looks and heft of it. Aluminium is bad for the brain and plastic is just bad. Function... Im not using a 200$ or more grinder or anything... Just fresh beans and a 30$ wancle amazon burr grinder and this is pulling beautiful bottomless shots that really helped me dial in better and see my channeling issues that intern lets me adjust and get better. The stock tapered basket prevents consistant tamps and keeps you from using off the shelf filter papers at the bottom of the basket. i have to use a gram or 2 more for my dose but that just means stronger drinks. I can tell visually im getting more extraction now that im dialed in by the color after adding milk.
