The Ultimate Bass Platform

The new DSM & Humboldt SIMPLIFIER BASS STATION is everything you ever needed to go direct to the FOH or recording amazing bass tones without sacrificing anything.  It includes a Bass Preamp with gain, level, and a 3 band EQ with semi-parametric mid control. A parallel signal routing with a selectable LPF, dual FX loop (for preamp and parallel signal), and an amazing analog cabinet simulation, based on the acclaimed Omnicabsim ® by DSM Noisemaker.

  • Mic cabinet simulation
  • Dual FX loop
  • Parallel signal chain
  • A full featured preamp based on the classic Ampeg SVT(C) amp.




Mic position:
Controls that responds like a real CENTER/OFF AXIS microphone position adjusting the precise amount of high-end roll off you look for. As usual with real mics and speakers, placing the MIC outside the center works best for distorted tones, and cleans sound best near the center.
Adjust the resonance
Cabsim Blend:
Blends the Cabsim in and out of the main signal.
Preamp Blend:
Blends the preamp signal and the parallel signal into the main signal. Start with this control at 100% and then blend in the parallel signal until you get the desired mix.
Sets the preamp master volume level.
Sets the gain of the preamp. It will produce a sweet SVT overdrive if set above 70%.
Controls the high frequency band, +- 15dB @ 3.5kHz , shelving.
Controls the mid band, -+ 15dB, bandpass, frequency according to the mid freq switch.
Controls the low end frequencies, +- 15dB @ 80Hz, shelving.
Phone Level
Controls the volume on the headphone output.

Toggle switches

Speaker color:
Bright: Aluminum cone speakers with their particular mid high bite. Modern: Flatter response with extra highs and lows Warm: Vintage speaker with clearer mid response and smoother highs.
Cab Size:
4x10 Vented: A modern standard with extended flat low end response and bright drivers. 8x10 Sealed : Huge sounding resonant low end cabinet with modern speakers. 1x15 Vented : Warm and well rounded, with extended low end, but the highs are creamier and less piercing.
Parallel LPF:
3 way toggle switch that enables a 2-pole LPF affecting the parallel signal. response of classic tube types: 100Hz: Deep low end preserved, and any harmonic content is filtered out. OFF: LPF disabled. 500Hz: Deep low end, and low-mids preserved in the parallel signal chain.
Mid Freq
Selects between 400Hz, 900Hz or 1500Hz for the mid control.


Parallel Phase
Some pedals invert the phase of the signal, this causes signal cancellation on certain frequencies, or even total cancellation if the preamp is flat and the parallel-preamp blend is 50%. Adjust if necessary.
Adjust this if you have a very hot bass and need to lower the gain (active), or compensate for a low level bass signal with a slight 6dB boost (Passive).

Ground Lift

Ground Lift
Disconnects the ground connection from the XLR out. Use in case you are getting hum problems when connecting to an external device.


Preamp FX - send:
The preamp FX send comes after the preamp. Put the effects for the preamp side chain here.
Preamp FX - return:
Return from the “preamp” signal chain effects.
Parallel FX - send:
The parallel fx send output comes from the input, before the preamp. Put the effects you want to use with the “clean” signal chain here.
Parallel FX - return:
Return from the “clean” signal chain effects
Connect the bass here
Carries the Main output (preamp + parallel blend) in a balanced signal.
DI out:
Carries the Main output (preamp + parallel blend) in a balanced signal.
DI Parallel:
Carries only the parallel signal chain (including the fx loop and LPF)
Aux In:
The auxiliary input receives a signal from an mp3 player, phone, or any audio device, and sends the signal in stereo to the headphone out. The aux signal will not sound through the regular outputs. Perfect for monitoring or late night practice.
Headphone out:
Connect your headphones here. Controls and Switches:
