Product Description

The BMAX is a high quality bass preamp/processor for the recording studio and on the stage. At the heart of the BMAX is a class A/B front-end, the input of which emulates the loading effect that the input of classic-design tube preamp would present to the bass pickups, and one of the key aspects in the warmth and punch of tube preamps. The BMAX also provides a pure and clean electronically-balanced DI output. From its 1/4" thick extruded front panel to thoughfully designed ergonomics to the red-abalone-topped knobs, the fit and finish of the BMAX exudes quality craftsmanship.


  • The BMAX is perfect anywhere an extremely high-quality, pristine preamplifier is required for the bass guitar
  • In the recording studio where a bass amplifier is impractical due to space or loudness considerations
  • In performance applications, where players will find the BMAX ergonomics intuitive and easy to use
  • The BMAX EQ and Dynamic controls, combined with the patented Sonic Maximizer processor, afford a wide palette of tonal choices

Overall Rating
Great pre-amp for diverse sounds
What is your overall opinion of this product?
OK - got this from AMS about 6 months ago and have been using it as the pre-amp before my Carvin 500 bass head. All i can say is this is a really great pre-amp and it really livens up my bass rig sound. I use the pre-amp into the power amp input of my head. I have both the compressor on and the BBE sound processing on with them all set to around half way. This seems to give the best sound as too much compression makes the sound cut off too much and too much of the BBE process makes it too boomy. With it on though it makes my highs a bit crisper and my lows a bit more present. The mids control is only a cut so i set it to a higher level so it doesn't cut as much to get a bit more mid-range. OTher than that it's now a keeper in my everyday rig - don't know what I'd do without it. THis is an all around great sound sculpting tool.
What is your opinion of the quality of this product? How does it work for different genres of music?
Solid quality - very solid feeling - nothing cheap or cheesy about it.
Are the features on the product what you were expecting? What are your favorite features?
Cut/boost on bass, treble but only cut on mids. there is a nice compressor built in and the BBE process boosts highs and lows. Bright switch to boost highs even more but i don't use it much - tends to make string noise more apparent and annoying - probably OK for slapping but I can get a really great slap sound without it so don't use it. Compressor and BBE process can be turned on/off.
How is the sound quality? How does the sound compare to other products you've use?
Sound quality is great. Better clarity, punchier lows and crisper highs. A/B it with/without on your bass head/rig and see - the difference is really amazing. I have a SansAmp pedal and i now prefer this instead. Yes, the SansAmp is nice but not as versatile as the BBE-Max and also does't have a compressor (which, in my opinion is a required tool to get a really good bass sound that is punchy and not boomy).
Are the controls logically laid out?
Controls are laid out nicely. Smooth pots - nice. Also, the controls are laid out logically - gain first, then tone modification controls like bright switch, treble, mid *cut*, bass, then mid sweep range/gain, then compressor and finally BBE process - just a well laid out signal chain.
How is the tone?
Great tone. This will bring any bass rig alive. I can't imagine NOT using it now that I've been using it for 6 months.
Did you get what you were expecting for the price? How does it compare to similar products in the same price range?
Great value at this price. I've seen it selling around and not found a better price except for used.
