BAS1 Bass Channel

Introducing BAS1 – the tone monster that’s about to change the way you experience your music. Picture this: every note you play takes center stage, oozing that authentic amplifier character that we all love. It’s like having a classic amp, but with a futuristic twist.

But don’t let the greatness fool you – BAS1 keeps things refreshingly simple. No need to decipher complicated controls. Take the preamp section, for instance – a single knob labeled GAIN is your ticket to sonic heaven. Plus, there’s an LED meter that’s got your back, helping you dial in that ideal Input Gain for the preamp, so you’re always in the sweet spot.

Caveman Audio taken inspiration from the legendary Urei 1176LN and given it a special twist tailored just for bass guitar signals. The result? Your bass lines feel more alive than ever. And guess what? This magical compression runs alongside your original sound, maintaining its essence and dynamics. It’s like giving your music a cozy blanket of warmth.

Here’s the real beauty: Caveman Audio done the hard work for you. Attack and Release times are pre-set, perfectly attuned for bass signals. You just handle the Threshold and the Output/Blend settings, and you’re golden. The kind of golden that takes your sound to a whole new level.

Now, get ready to sculpt your sound with finesse. The BAS1 got a two-band parametric equalizer and a trusty Bass control ready to rock. Whether you’re looking for that thumping low end, a mid-range punch, or a crisp high, Caveman Audio got you covered. And don’t worry about getting lost in the technical stuff – they made sure it’s intuitive.

Feeling the groove at 80Hz? That’s where the Bass control works its magic, focusing on that soul-shaking sweet spot. The Low EQ? It’s got the 150 Hz – 3 kHz range locked in. And the Hi EQ? That’s cruising through 600 Hz – 10 kHz. Both EQ bands offer up to +/- 15dB to play with, and they’re designed with that musician’s touch in mind.

As you’re dialing in that perfect sound, the Master Volume slides in for the finishing touch. And when you want silence to speak volumes, the MUTE function steps up.
