Lichtlaerm Audio Altar Heavy Doom Sludge Fuzz

The Lichtlaerm Audio Altar Heavy Doom Sludge Fuzz is a high-gain fuzz pedal aimed at doom and sludge players, listed at $219 (€199) as of December 2024¹. It sits in the fuzz family but is built to be far more adjustable than a typical one-knob fuzz, with a full EQ section, a footswitchable boost and switchable clipping styles.

Guitar Pedal X's Stefan Karlsson, reviewing it among the best new fuzz pedals of 2024, was emphatic¹:

He also found it "far more expansive than the Blackhawk Balrog", and noted that it "can be run much lower gain without a hint of doom overall", meaning players outside doom and sludge can dial it back into more ordinary fuzz and drive territory¹.

Controls

The Altar's control set is unusually deep for a fuzz, covering EQ, gain staging, clipping character and a boost curve¹:

The Grind control's HM-2 curve references the scooped, chainsaw-adjacent mid shape associated with that style of extreme metal voicing, applied here to the boost stage¹. The Comp control's three clipping styles mean the Altar can lean toward overdrive or distortion flavors as well as full fuzz, which is what allows the low-gain, non-doom settings the reviewer described¹.
