The Orbit Model T Preamp is not your ordinary Sunn Model T clone. It is an all-in-one booster, preamp, toneshaper, distorter, and overdriver with fuzz-range potential. This pedal is highly responsive not only to your playing dynamics, but also to whatever pedal that goes in front of it, pushing your instrument into another dimension of doom tonal quality.

In The Beginning…

Your input signal is split in two and fed into parallel, tube-amp emulating gain channels—Normal and Bright—for a complete range of grittiness perfect for when you want to add some dirt into your signal. The bassier Normal channel brings out the boom from the low end of your instrument’s frequency range. The Bright channel produces more treble, great for highlighting the added harmonics of your dirt pedals. Together, the two add a subtle compression that works beautifully when the Orbit is used as an always-on pedal at the end of your signal chain.

Fire and Ice

Unlock Fire and Ice modes with the Gain footswitch, which toggles between two incredible gain ranges by overdriving (or backing off from) the circuit’s internal gain stages. The gain ranges are denoted by the pedal’s indicator LED changing its colors. Ice mode (with its blue LED) produces a cooler overdrive, and is great for players who love low-gain overdrives, and for stacking multiple gain pedals in series. Fire mode (i.e., the LED goes red) gives you hotter distortion tones, for those who want nothing more than to blast their amps and scorch the earth behind them.

Tone Shaping

The gain stages are immediately followed by a passive Fender-style tone stack for intuitive and unique toneshaping capabilities, with three controls to help you modify your frequency response. Note that the mid frequency range on a stock Fender tone stack is naturally scooped, and is highly responsive to the Bass and Treble control. With the Treble almost all the way down, the mid scoop starts to appear at about 2 kHz, with a considerable bump in the bass. As the Treble increases, the mid scoop can reach ranges of 400–550 Hz, with the Mid knob simultaneously controlling both the range and amount of scoop. A somewhat flat response can be achieved with the Bass and Treble controls almost all the way down and the Mid control around center.

Get Loud

To compensate for the tone stack’s natural tendency to reduce the signal output gain, a clean volume boost has been integrated at the last stage of the circuit. This allows for greater flexibility in using the Orbit as a lower-gain overdrive by simply lowering the Gain controls while increasing the Volume.


  • Classic tube amp emulation using high-quality, carefully biased JFET transistors
  • Two gritty input gain channels in parallel: Normal and Bright
  • Fire and Ice modes toggled by the Gain footswitch
  • Fender-style tone stack featuring mid-scoop and controls for Treble, Mid, and Bass
  • Clean volume boost following the tone stack for output gain compensation
  • Stackability – This pedal gives new textures and highlights to a huge range of other circuits that you can place before it. Try it with a Rat, Big Muff, DOD 250, Tonebender, or anything else you can throw at it.
  • Dual-color indicator LED denotes the active or bypassed circuit, as well as Fire and Ice modes
  • Perfect for both guitar and bass, with passive and active pickups
  • True bypass, heavy-duty on/off footswitch
  • Top-mounted jacks

Shipping Information

Processing Time:
Depending on availability, the time I need to prepare an order for shipping varies. For custom builds, please allow 3-4 weeks lead time. For finished builds, please allow 1-2 weeks for processing.

Estimated Shipping Times:
Eco Post: 7–5 business days estimated distribution time for most destinations (see below), 10–12 business days estimated distribution time to Australia and Hong Kong.
Registered Mail: 4–8 weeks
I will do my best to meet these shipping estimates, but cannot guarantee them. Actual delivery time will depend on the shipping method you choose.

*** UPDATE***
Postal systems around the world appear to still be adapting to the global impact of COVID-19. This means that shipping times may be longer than we had previously been used to. I ask that you please be patient while we track the status of your package together.

Shipping Methods:
I ship out all pedal orders via Eco Post. This method is typically quicker than Registered Mail (advertised estimation is 7–5 business days, but due to the current situation has been known to take a bit longer, depending on the country), and it also features computerized tracking and proof of delivery.
This method is available in the following countries: Austria, Australia, Italy, Ireland, the United States, Belgium, Brazil, the United Kingdom, Germany, Denmark, South Korea, the Netherlands, Hong Kong, Greece, Japan, Norway, Spain, Poland, Portugal, Finland, France, Canada , Sweden, Switzerland, Thailand, Russia.

For PCB orders, you can choose between Eco Post and Registered Mail.

Customers living in Israel can arrange for Local pickup, just contact me for arrangements.

Customs and Import Taxes:
Buyers are responsible for any customs and import taxes that may apply. I am not responsible for delays due to customs.


Each Carcharias Effects pedal is hand-made by one person in his home workshop who loves making music, and making things that make music. Every purchase you make enables me to continue making more pedals, so your support is very much appreciated. That said, I take responsibility for the build quality of every pedal I make comes, and offer a 24-month warranty on each one, not covering normal wear-and-tear or abuse.

All the PCBs that I sell on this site were designed personally by me, but the fabrication is outsourced to third-party PCB fabrication services. Once they are designed, I order them in relatively small batches. I personally test every batch that I receive; however, as I am a strong believer in minimizing waste, there are cases in which I may sell perfectly functioning PCBs that might have some design flaw. I take responsibility for these design flaws (if any) and will specify their fixes or workarounds in the product's specific build document.

If you should encounter any issues with your product, please feel free to reach out to me via the contact form on this website. As I am based in Israel, I understand the inconvenience added by international shipping, and so I will be happy to assist in troubleshooting with you any problems before resorting to international shipping in case a repair needs to be made.
