What we have here are my new “PVMB” series of bass amp settings.

These are a much different approach to the EQ curve than before.

More low mids and brighter overall. The SVT Brt, GKCougar, and Del Sol turned out great and are very similar. Enjoy !!

Have Fun !!!


Another huge factor to consider in dialing in a tone is the frequency that you are actually hearing vs the frequency that you think you are hearing.

When you strike a Low E string the fundamental 41Hz peaks and drops within the first second, 82Hz and 164Hz peak at the same rate but drop at a significantly slower rate than the 41Hz. Pumping the Low E will create a sea of standing waves that won’t take long to cancel each other out, if you are only focusing on the sub harmonic frequencies.

I’ve personally had far more luck focusing on the 2nd and 4th harmonic overtones of the note. The waves are shorter and carry more punch. Example being. On an E string I will focus my frequencies around 82 and 164hz It’s the same frequency as E (41Hz). I have far less issues with low frequency cancellation, the stage is less muddy, and I have greater clarity hearing myself.

Full Range Flat Mid

Here are the settings for my new F.R.F.M. series of Helix Bass Amps.

Full Range Flat Mids were created to provide smooth, mellow bass tones that will sit in a mix without being overbearing.

Be sure to add the high/low cut EQ after the amp block to help keep things under control.

Have Fun !!!

GK Slap, Tap, and Finger

I had a request for a simple GK preset that would provide a balance of slap, tap, and finger style playing.

Here are the settings I came up with for a Jazz Bass.

Drive. 5.0
Bass. 6.0
L. Mid. 2.0
H. Mid 3.0
Treb. 4.0
C. Vol. 7.0
M. Vol. 10.0
Boost. 5.0
Cont. ON

For additional “Marcus Slap” sound, add a 500hz...1.0 Q...-8.0dB after the amp block.

Low cut 30hz...High cut 8kHz Have fun !!

Studio Tube Bass DI

So, I offer you the Studio Tube Bass D.I.

I’ve been wrestling with this one for awhile, and sometimes the absurdity is slapping you right in the face. Always experiment with the digital world.

I was waiting to change these super dead strings to show how much life this preset can add. It’s easy to dial in.

Add a Low/High Cut block first and set to 20Hz and 20.0kHz @ -2.0dB Level

Bass EQ

Here is my “guide” to Bass EQ…


Low Cut to remove excessive seismic lowend and increase headroom.


Boost with Wide Q to bring the low end closer to the listener.


Cut -3dB to reduce mud


Boost makes bassline stand out more in a mix.


Boost to bring out more attack of the string. More “pluck” sound


Boost/Cut here for the finger on the string noise.

Remember we are all after different tones so these points are simply “safe zone” to start sculpting.

Balanced EQ

For new members who are having a difficult time dialing in a good starting point for bass tones. These are settings that I’ve optimized for bass, following an exact EQ curve that Leo Fender discovered decades ago and it has been the foundation for great bass tones.

It’s also a fantastic way to hear the subtle differences between all the amps as well. I followed a strict tuning process monitoring over 50 different frequency points with a tolerance of +/- 0.5dB

The main tonal variation will happen because of the limitations of each amp in the lows and highs.
All output volumes are matched as well.

Here are my balanced EQ and output settings for each bass amp to provide a better starting point when dialing in your amp tone. I highly suggest making 12 new presets having one amp block per preset, so you can quickly switch between them all to hear how they sound.

These settings actually sound pretty great with no cabinet or IR needed.
