Remember that you can only manage one unit at a time.

Q: How is the XTOMP CDCM technology different from similar modeling systems?

A: Hotone’s new era XTOMP is the fruit of a decade of circuit modeling research and development and employs our very own Comprehensive Dynamic Circuit Modeling (CDCM) system. CDCM has constructed an extremely complex dynamic variation matrix, able to realistically express every detailed change that occurs during the operational process of actual circuitry. That is to say, as XTOMP is operating, the models at work within it are constantly changing rather than remaining fixed. This matrix will adjust its own modeling parameters and even framework based on the instrument input signal range, signal frequency, knob position, the instrument’s own impedance, and other variable parameters, all to achieve the closest possible characteristics of actual circuitry. CDCM can also accurately model a specific aspect of a circuit, including slight variations between resistors or capacitors, in detailed description. This modeling technology is made possible by the powerful processing capability XTOMP boasts in its internal floating point DSP chip. The chip focuses all of its power into recreating the tone of a single effects model algorithm. This ensures the effects model gets all the processing power, and that’s why it sounds so realistic. Other modeling products rely on a single chip to process a number of algorithms in series, which weakens the calculation and processing resources that any given model actually receives, resulting in a lower degree of accuracy.

Q: Where do the original effects units that XTOMP models come from?

A: Since all of XTOMP’s modeling is based on actual circuitry, Hotone had to find the actual original units featured in the XTOMP model library. In order to capture the most meaningful tones, Hotone spent a great deal of resources in obtaining those classic effects which have long since disappeared from the market. We are also very grateful to those friends who lent their vintage effects to our modeling research. The model library is always open, and we hope that Hotone friends worldwide with antique original gear will reach out so we can add their priceless tool to the family.

Q: Can XTOMP model other digital gear?

A: The Hotone research team came out with a digital modeling technology based on “black box theory” (different from CDCM) as early as 2001. The answer to whether or not XTOMP will model digital equipment in the future depends on customer demand!

Q: Will Bluetooth download affect the XTOMP tone in any way?

A: Bluetooth perfectly transfers the model to the XTOMP unit, ensuring pure tone and flawless functionality. Hotone also designed XTOMP to keep the Bluetooth signal from interfering with other nearby frequencies.

Q: How were you able to make XTOMP so thin?

A: Even as Hotone demanded excellence in XTOMP’s circuitry and digital capabilities, we also had a high standard for its structural and aesthetic design. This design process spanned eight months, and the team came up with some unorthodox methods to reach the product’s ID goals and structural demands. One of these can be seen in the kick switch, which is unlike switches used in most other stompboxes that take up all of the internal space below them as the switch peg goes down deep into the box. XTOMP features a Tact Switch, which operates according to lever theory and leaves the inner casing more room for essential circuitry. The XTOMP design process is a classic example of Hotone’ s drive to “challenge the limits of design,” a principle that can be seen featured in several of the company’s products, many of which have been granted design patents.

Q: What do the lights under the XTOMP knobs do?

A: With vintage equipment, the number of adjustment knobs obviously varies from pedal to pedal. That’s why XTOMP is fitted with multicolored lights underneath the knobs that show which knobs are for use as the unit “becomes” the stompbox it is modeling. Of course, these lights also make settings easy to see and are super cool looking on a dark stage. For some models, the lights indicate the status of a knob setting. For example, if the original equipment had a toggle switch, that function will transfer to the XTOMP and be controllable in knob form. You can set up a color code in the App to show, for example, Boost ON/OFF. Set a knob light to change from say red (OFF) to green (ON), as you turn it and adjust your settings.

Q: Do I have to have a smart phone for the XTOMP to work?

A: Even though pretty much everybody has a smart phone, XTOMP is also equipped with a USB port for model updates, which means, you can use our free PC and Mac apps to manage your XTOMPs. Hotone also has plans to add computer Bluetooth connectivity in the near future.

Q: Do I have to purchase XTOMP models?

A: All current XTOMP models are free.
