The Broughton Audio Sunder Fuzz 10th is a fuzz pedal built for bass or guitar, marking the tenth anniversary of the original Sunder Fuzz. Broughton Audio describes it as taking "the original crushing fuzz and adds a clean low passed signal for even more heavy". The fuzz itself comes from a differential transistor pair, which the maker says generates heavy upper harmonics that create a wall of sound for bass or guitar, suited to heavy metal, synth, or any scenario where you need a massive fuzz tone.1
The clean blend is the core idea of the 10th Anniversary version. The low passed clean signal is taken post gain, so as you turn the gain up, you get even more clean lows available, keeping the low end full and dynamic under the fuzz.1
Controls
| Control | What it does |
|---|---|
| Low | Volume control of the low passed clean signal1 |
| High | Boost/cut of the treble frequencies1 |
| Mid | Boost/cut, with the center frequency variable from 200 Hz to 2 kHz1 |
The Low knob is the change that defines this version: on the original it did something else, and here it has been repurposed to set the level of the clean low end blended back in after the fuzz.1
Power
The pedal accepts 9 to 24 volts DC and draws approximately 20 mA. It uses a standard Boss style connector with center negative polarity, the same type as most pedalboard power supplies. The DC supply is not included.1
The Sunder Fuzz 10th uses a true bypass switch.1
Warranty
Broughton Audio covers its products for one year to the original owner.1
Where it sits
As a fuzz with a clean low blend, the Sunder Fuzz 10th belongs alongside other fuzz pedals aimed at bass players, and within Broughton Audio's own range of bass-oriented pedals such as the Broughton Audio Calamity, the Broughton Audio Helion, the Broughton Audio Bass Box and the Broughton Audio Azure Drive 10th.1
Questions
Can the Sunder Fuzz be used on guitar as well as bass?
Yes. Broughton Audio describes the Sunder Fuzz as a fuzz pedal for bass or guitar. Its differential transistor pair generates heavy upper harmonics that create a wall of sound for either instrument, and the maker suggests it for heavy metal, synth, or any scenario where you need a massive fuzz tone.
Does the Sunder Fuzz come with a power supply?
No. The maker's product page lists the pedal as taking a DC supply with a standard Boss style connector, center negative polarity, but the DC supply is not included. The pedal accepts 9 to 24 volts and draws approximately 20 mA.
What is the polarity of the Sunder Fuzz power jack?
The power jack uses center negative polarity with a standard Boss style connector, according to Broughton Audio. That is the same connector type used by most common pedal power supplies and daisy chains.
What does the Low knob do on the Sunder Fuzz?
On the 10th Anniversary version, the Low knob has been repurposed as a volume control of the low passed clean signal. That clean signal is taken post gain, so as you turn the gain up, you get even more clean lows available, which keeps the low end full under the fuzz.
What is the warranty on the Sunder Fuzz?
Broughton Audio covers its products for one year to the original owner, which includes the Sunder Fuzz 10th.
