Introducing the Caveman Audio BAS1 Bass Channel


This is the most impressive sounding piece of bass gear I have seen to date.

I am completely blown away by the thoughtful and highly flexible yet simple to use design, and the fact that it is dead quiet and completely musical. 

I have tried it with many different types of basses, and it makes every bass sound better than I even knew that bass could sound. 

If you can visit the shop, please make an appointment to try it out, you will not be disappointed.


The fact that Mark King uses the BAS1 was enough to convince me of its quality, but now that I have heard it for myself, I can confidently recommend it to anyone who owns a recording studio where bass guitars are recorded, and to anyone who plays bass guitar and will not settle for anything less than the very best possible tone they are capable of producing with their instrument. It simply doesn't get any better, full stop.


I will be creating a demo recording as soon as time permits. Check back here for a link to a demo recording, it should be available before the end of April.


In the meantime, see below for some info about the BAS1 taken directly from the Caveman Audio website.


I have two units in stock and available for immediate delivery.

The footswitch, footswitch cable, and power cable are all included.

It also comes with a set of self-adhesive rubber feet that you can install if you don't wish to rackmount it.


The ultimate low-end system for creating ultimate bass tones 


What would you use in the studio to get the best possible bass sound?

1: A great sounding preamp.
2: Parallel compression.
3: EQ. 

This is exactly what BAS1 gives you! It simply represents the peak of our skills and efforts. And the result is without doubt the finest Bass Preamp that we could have ever imagined crafting.

It is designed to run directly to a FOH-console or the mixing desk in the studio via a transformer-balanced DI We even added a transformer-balanced AMP OUT to feed your amplifier/monitor on the stage.

  • Neutrik gold-plated ¼” Cable input
  • Transformer-balanced Neutrik gold-plated XLR Wireless input
  • Transformer-balanced Neutrik gold-plated XLR DI output
  • Transformer-balanced Neutrik gold-plated ¼” TRS out for external amps 
  • Adjustable Input Gain
  • Studio Quality Parallel Compression
  • Studio Quality 2-band Parametric EQ with Bandwidth ("Q") control
  • Studio Quality Low-End control
  • Overall Master Volume
  • Mute function
  • Tuner Output
  • Worldwide voltage compatibility


BAS1 is a tone monster that will make every note you play stand out clearly and with the character and definition of a genuine tube amplifier.

Great sound does not have to come with a complicated user interface. On the contrary, BAS 1 is fairly simple to operate. For instance, the preamp section holds only one control – GAIN! An LED meter helps you to dial in the best Input Gain level for the preamp.

Next up is the compressor section. This is our version of the legendary Urei 1176LN – but with increased attack time with the sole purpose of suiting bass guitar signals perfectly. Further, we have designed it to run in parallel with the original signal in order to maintain the integrity of your signal and its unique and characteristic dynamics. The parallel compression design gives your sound ‘body’ and ‘foundation’ in a way that an equalizer could never do.

We have pre-set the Attack and Release time inside the unit – again specifically with bass signals in mind. All you need to do is to dial in the Threshold and Output/Blend settings. This is one killer effect for sure.

Finally, we have added a two-band parametric equalizer and a fixed Bass control that lets you sculpt and fine-tune the bass sounds that dreams are made of!

The Bass control operates with a very narrow bandwidth at 80Hz. This is where we believe the low end of a bass excels.

The Low EQ operates within the 150 Hz – 3 kHz frequency range, and the Hi EQ spans the 600 Hz – 10 kHz frequency range.

The Level range is +/- 15dB for the Low and Hi EQ bands – and both feature variable Q control.

A Master Volume at the very end of the signal chain and a MUTE function completes BAS1.
