The Roadie 3 is also a control is some sense since it has the coolest feature (automatic tuning) but a low accuracy of 2 cent, to see if people choose features over accuracy. The Boss Chromatic Tuner is also there as sort of a Control. (Another side-note, these specific tuners were chosen due to their higher order of features and higher degree of accuracy above other tuners this was not meant to discriminate against chromatic tuners vs strobe tuners and there was no brand loyalty bias, these were simply chosen based on searches for 'reviews of the best tuners'. So let's just focus on the best tuner and not on whether one should have a dedicated tuner pedal in the first place for now!) There are many people who prefer to have a separate tuner pedal for various reasons. And you get the ability to use batteries and an extra power jack on your tuner Or a GFI System Skylar + cash from my end. I am looking to trade for a ST-300 Mini please. Comes with original box, manual and accessories. And if one cares about having a dedicated always-on tuner, this is still a relevant question to ask. Hi there, Up for sale/trade is a like new Sonic Research ST-300. (Side-Note: Of course someone can always say 'Well just use the tuner built into pedal X and save space', but in most cases, the accuracy of these tuners is much lower (or unpublished because it's not accurate). These all have their strengths and weaknesses. The TC Electronic and Sonic Research tuners have a tiny version Peterson doesn't offer a tiny-pedal equivalent to the StroboStomp. The Polytune and StroboStomp promise the same accuracy, and the PolyTune has a mode to strike a chord and tell you which string is out of tune, not present on other tuners. The StroboStomp still has the nicer, better display, and also pass-through charging up to 900 mA of current, allowing it to be useful for adding an extra outlet to larger boards. However, I've rarely seen this on anyone's pedalboard, and I never see anyone talking about this pedal, and it appears as though its UX design is not as great. I was convinced that their StroboStomp would be the most accurate equivalent pedal at 0.1 cent, but then I found that the Model ST-300 by Sonic Research promised a 0.02 cent accuracy and in a smaller form factor. I like the Peterson clip-on tuner with its strobe display.
