The Aguilar Fuzzistor is a bass fuzz pedal from Aguilar Amplification, built around an analog silicon transistor distortion circuit. Aguilar pitches it at "epic, classic fuzz bass tones," and its defining feature for bass players is a Blend control that mixes your clean signal back in with the fuzz, so the low end does not disappear when the distortion kicks in1.
Premier Guitar reviewed the pedal and found it solidly made, noting it is "housed in a rugged and weighty orange-metal enclosure devoid of gaudy graphics" and calling it "Built to last." At the time of that review it sat at a $159 street price2.
The controls: Fuzz, Tone, Level and Blend
The Fuzzistor carries four knobs, which Premier Guitar described as "a quartet of smooth-dialing knobs for blend, level, tone, and fuzz"2.
| Control | What it does |
|---|---|
| Fuzz | Sets the amount of fuzz distortion2 |
| Tone | Shapes the fuzz; only affects the distorted signal, and provides nuance to the fuzz when swept2 |
| Level | Sets the output volume of the pedal2 |
| Blend | Mixes the clean and fuzz signals, giving complete control over the balance1 |
The Blend knob is the one that matters most to bass players. Because it "allows you to get ideal mix of clean and fuzz tone," you can keep a clean, full low end underneath as much or as little fuzz as you want, rather than committing your whole signal to the distortion1.
The Tone knob works differently from a tone control on a clean pedal: Premier Guitar's reviewer "especially dug the sensitivity of the tone knob (which only affects the distorted signal) and the available nuance" it offered when swept2. Your clean signal stays untouched no matter where the tone is set.
Power and connections
The Fuzzistor is simple to wire up: one 1/4" input jack and one 1/4" output jack1.
The Fuzzistor has no battery option. It runs on a universal 9-volt power supply only, and the supply is not included with the pedal1.
Its 4.5mA current draw is light enough that it will not put real pressure on a pedalboard power supply3. Aguilar covers the pedal with a three year limited warranty to the original owner against defects in materials and workmanship1.

Questions
Does the Aguilar Fuzzistor take a battery?
No. The Fuzzistor is powered by a universal 9-volt power supply only, and the supply is not included with the pedal, so you need to add one to your board's power setup before you can use it.
Does the Fuzzistor tone knob affect the clean signal?
No. Premier Guitar's review notes that the tone knob only affects the distorted signal, so your clean signal stays untouched no matter where you set the tone control. Sweeping it provides nuance to the fuzz character.
How much current does the Fuzzistor draw?
The Fuzzistor draws 4.5mA, which is a very light load. Even a modest pedalboard power supply can run it alongside several other pedals without strain.
Is the Aguilar Fuzzistor analog?
Yes. Aguilar describes it as analog silicon transistor distortion, built around a silicon transistor fuzz circuit rather than digital processing.
What warranty does the Fuzzistor have?
Aguilar Amplification covers its products with a three year limited warranty to the original owner against defects in materials and workmanship.
