The Fuzzlord Effects Model T150 Preamp is an analog preamp pedal built around the circuit of a legendary amplifier. Fuzzlord describes it as "inspired by the rare and highly coveted Sunn Model T amplifier," and says it captures that amp's "snarling aggression, massive headroom, and the rich harmonic content." The Sunn Model T was a 150W amp from the sixties, known for its monstrous tone: lots of bass and heavy distortion12. The T150 puts that character on a pedalboard as a preamp that can drive an amp or power amp directly.
What it does
The T150 is a preamp, not a distortion pedal in the usual sense: it recreates the gain and voicing stages of an amplifier so the pedal itself can act as one. Fuzzlord says an internally boosted power supply lets the pedal deliver "towering volume with enough headroom and punch," which matters because a preamp designed to stand in for a 150W amp needs more internal voltage than a standard 9V circuit alone provides2. The maker states that its "analog stages were carefully voiced to mirror the frequency response" of the original amp, so the tonal shaping happens in analog circuitry rather than digital modeling2.
The controls
The T150 has six knobs, laid out like the channel and EQ sections of the amp it is based on2:
| Control | What it does |
|---|---|
| NORMAL | Dials in thick, saturated tones from the Normal channel, with its classic low-end-focused rumble |
| BRITE | Adds bite, presence, and aggressive edge via the bright channel |
| BASS | Shapes the low-end foundation |
| MID | Carves out presence in the mix, from scooped to pushed forward |
| TREB | Adjusts high-end clarity, from dark and moody to searing brightness |
| MASTER | Sets the overall output volume |
The NORMAL and BRITE knobs are the heart of the design. They correspond to the two channels of the Sunn Model T: the Normal channel is the darker, bass-heavy side, while the Brite control brings in the brighter channel's bite and edge. Blending the two lets a player shape how much saturation and top-end aggression the preamp carries into the rest of the rig2.
The pedal requires a 9V center negative 2.1mm isolated power supply only. There is no battery option, and the maker's wording rules out daisy-chained supplies. Budget 45mA of current from the supply2.
Size, build, and availability
Fuzzlord lists the enclosure at 120 x 94 x 42.5 mm and calls it compact and pedalboard-friendly. The finish is a rugged powder coat with UV printed artwork, and product images show a red splatter finish option2. The pedal was listed at $259.00 USD on the maker's product page as of 17 October 20262. Fuzzlord's stated returns policy accepts returns within 3 days of delivery, with the buyer paying return shipping2.

Questions
Is the Fuzzlord Model T150 analog or digital?
It is an analog pedal. Fuzzlord Effects says its analog stages were carefully voiced to mirror the frequency response of the Sunn Model T amplifier the pedal is inspired by. There is no digital modeling involved, and the internally boosted power supply gives the circuit the headroom it needs for high-output preamp duty.
Can the Fuzzlord Model T150 run on a battery?
No. Fuzzlord Effects specifies a 9V center negative 2.1mm isolated power supply only, so there is no battery option. The pedal draws 45mA, and the maker calls for an isolated supply rather than a daisy-chained one.
What power supply does the Model T150 need?
A 9V center negative 2.1mm isolated power supply, and nothing else. The pedal draws 45mA, which is well within most isolated supplies, but the maker is explicit that an isolated supply is required.
Is the Fuzzlord Model T150 true bypass?
Yes. The pedal uses true bypass relay-based soft switching, which Fuzzlord Effects describes as delivering seamless transitions when the pedal is engaged and disengaged.
What is the difference between the Normal and Brite controls on the T150?
The NORMAL control dials in thick, saturated tones from the pedal's Normal channel, which Fuzzlord describes as having a classic low-end-focused rumble. The BRITE control works the bright channel instead, adding bite, presence, and aggressive edge. Together they let you blend the two channel characters of the original amp.
How big is the Fuzzlord Model T150 pedal?
Fuzzlord Effects lists the enclosure at 120 x 94 x 42.5 mm and describes it as compact and pedalboard-friendly. The finish is a rugged powder coat with UV printed artwork.
