The company's founder and CPO is Daniel Schwartz, who is also credited as the designer of the Simplifier X21. Around the Simplifier family, DSM/Humboldt has built out a range that includes the Dumblifier two-channel overdrive, a dedicated bass lineup, and drive, compressor and distortion pedals.
The Simplifier: analog amp and cab simulation
The product the company is known for is the Simplifier MK-II, an analog amp simulation pedal that DSM/Humboldt calls "The State-Of-The-Art on Analog Amp simulation," packed into what the maker describes as an ultra compact footprint, the same size as the original Simplifier7. The earlier Simplifier Classic is described by the maker as a "100% true analog preamp"8, and its power-tube section includes a KT88 position the maker says is "Similar to 6L6 but with improved low-end range, perfect for bass or 7+ strings guitars"8.
The family has since grown:
| Pedal | What it is |
|---|---|
| Simplifier Classic | 100% true analog preamp with power-tube and cab simulation8 |
| Simplifier MK-II | Analog amp simulation pedal in the original's compact footprint7 |
| Simplifier X | The maker's most advanced analog amp simulator, designed by Daniel Schwartz21 |
| Simplifier DLX | Pedal-format member of the Simplifier family9 |
For players comparing formats, the Simplifier X and Simplifier DLX are both analog amp simulator pedals; the X is the one the maker positions as its most advanced, while the DLX keeps the concept in a standard pedal format29.
The bass lineup
Bass players get their own branch of the Simplifier. The Simplifier Bass Station is a bass preamp with DI and analog cabinet simulation, based on the Omnicabsim by DSM Noisemaker, with gain, level, a 3-band EQ with semi-parametric mid control, a parallel signal routing with a selectable LPF, and a dual FX loop1011. The maker pitches it as "everything you ever needed to go direct to the FOH or recording amazing bass tones without sacrificing anything"1211.
The newer Simplifier Bass Master is a bass preamp pedal with a new cabsim and a 4-band equalizer, which the maker calls "the culmination of years of research over the different factors that interact" to shape bass tone1314. The company published a demo of the Bass Master with Ben Jud14.
The Dumblifier and the rest of the range
The Dumblifier is a two-channel overdrive pedal that the maker says "can operate as a complete analog amp replacement with cab-sim and stereo features, or as a two-channel overdrive pedal," packed into a pedal format "without the cost or fragility" of an amplifier15. It includes a reverb section, with the amount controlled by a REVERB knob on the front of the pedal15.
The wider range covers:
- Black Clouds, a distortion pedal the maker bills as "The Ultimate Distortion"16
- Silver Linings, a drive/preamp pedal designed under lockdown, which the maker says was built to "bring rays of joy and inspiration"17
- ClearComp 1078, a compressor pedal "inspired by studio comp/limiters, but at your feet"18
