We offer a wide variety of products, and the following precautions apply to some of them. Please note that they are listed for all products. 【Voltage Compatibility】Designed for Japanese voltage (90-110V). Using with a different voltage may cause malfunction. 【Plug Type】Japanese plugs (A or B type). Use a conversion adapter if needed. 【Transformers & Adapters】Transformers adjust voltage; adapters only change plug shape. Using an adapter without a transformer may damage the product. 【Liability】We are not responsible for damages caused by improper use, such as using the product without a transformer. Dimensions: 121x64x57(mm) Power consumption: 10mA Input impedance: 50kOhm Output impedance: 10kOhm Power supply: This product can be used with a 9V AC adapter and a 2.1mm center negative adapter. We do not recommend using daisy chains or non-transformer power adapters, as they may generate noise. [Flexi-Switching] This product is equipped with a Flexi-Switch function. It is an electronic relay type true bypass, and depending on how you press it, it can be used as a normal latch type switch. Since it uses an electronic relay type switch, the input signal will not be output unless power is supplied. "Hunmmingbird" has been one of our popular effects since its introduction in 2007. The first unit started out as a slightly modified clone of the popular vintage "VOXRepeatPercussionTremolo", a popular tremolo that can be used like a delay, but in 2009 we added a JFET to give it more headroom, and changed the circuit to allow flexible control of the tremolo with Depth and Level. In 2015, we made further improvements and changed to a new circuit. As a further improvement, we have added a third mode that allows you to change the speed. It is now possible to choose between 1 and 2, which were in the original. With this improvement, you can easily create tremolos that are unbearably slow, fast tremolos like ring modulation, and everything in between. It is also possible to quickly adjust the tremolo speed from the outside with an expression pedal, and by treating the expression pedal like a wah, it is possible to manipulate a variety of tremolo changes in real time that were not possible with the original.
