Description
Model feT
The Model feT is a transistor-based preamplifier designed around the legendary Sunn Model T amplifier. Those who have played the original know that while it excels at heavy tones when pushed, it is far more than just an amp for stoner rock and doom metal. In fact, on its own it is a fantastic mid-gain amplifier with a tone that is dark, yet clear and present—making it an exceptional pedal platform.
Most famous Model T tones come from putting a distortion or fuzz in front of the amp. Thus, the Model feT is designed to sound good on its own and with other pedals stacked in front. This pedal goes beyond the standard triode-to-JFET emulation approach with the inclusion of an emulated power amp. This broadens the range of gain and—in the true spirit of the original amp—allows for massive headroom and volume output. This greatly expands its capabilities beyond a typical drive pedal: the Model feT can be used directly into a power amp, cab simulation, or DAW.
Electrical Specifications
-
Bypass: Relay switching with true bypass
-
Input impedance @ 1 Khz: 500kΩ
-
Output impedance @ 1 Khz: 1kΩ
-
Power: 9V DC, 2.1 mm center negative barrel. The current draw is 65 mA.
We recommend a regulated, isolated power supply rated for 100 mA minimum. Our pedals do not accept batteries. Use of an incorrect power supply may cause permanent damage.
Controls
-
Normal: turn clockwise to add gain from the parallel “Normal” channel, which has a neutral voicing. Higher settings produce a thicker gain sound. The normal channel is fully muted when this control is at zero.
-
Brite: turn clockwise to add gain from the parallel “Brite” channel, which is voiced for extra midrange and sparkle. Adds bite to the drive tone at higher settings. The “Brite” channel is fully muted when this control is at zero.
-
Bass, Midrange, Treble: 3-band FMV EQ with the same moderately mid-scooped voicing as the original amp: highly interactive and nonlinear, but familiar.
-
Master: sets overall output volume. This control is capable of high volumes in order to access quieter clean settings and to properly drive an external power amp.
