Submarine Designer Bass Preamp Pedal with UltraBASS

Submarine Designer Bass Preamp Pedal with UltraBASS

We call it the little sparkling thing!

As the name suggests, Submarine Designer is built based on one of our best selling pedals, the Submarine. If you set all the toggles to “SUB” position, the core of the sound would be identical to the regular Submarine. While Submarine is versatile enough for most bassists, some of us need more control over pedals to get “exactly” what we want and we also know about the shortcomings of further EQ adjustments (overlapping frequencies, less-than accurate curve representation, etc). If you are not scared of knobs and switches, and you never get tired of trying out new sounds; then Submarine Designer is the ideal tone shaping preamp for you.

Start with all toggles at “SUB” position, tone control set to middle and body control points the star. That is your reference tone. Adjust the rest by using very informative captions, such as 250 Hz dip or 600 Hz boost. Do you want to overdrive your old school all tube preamp? Easy! Just set it to boost mod. Do you want 100% flat signal and just want additional volume boost with some warm/vintage vibe? Just set everything but the left bottom switch to “SUB” position. You want you bass to sound like an ice pick? You want your horns to sizzle? Just rotate tone control clock-wise. There more more than several dozens of combination available if you can make use of all the switches and knobs.

Just like Submarine, Submarine Designer is also designed to be a tone shaping preamp. That doesn’t mean you can’t use it to properly drive a poweramp, because it is capable of more than fair amount of clean boost. It will never be distorted when the volume is cranked (and boost toggle at “SUB” position), even if you use very high output active bass guitars. If you are a recording musician, you will enjoy the tones you can get out of Submarine Designer as well, sitting right in the mix with minimal post-processing.

The addition of UltraBASS switch, the user would be able boost the bass and sub-bass frequencies regardless of the tone control position. Our collaboration with Kreuzer Electronics allowed us to build the best Submarine of all times.

For information on how we record samples, please visit Recoding FAQ page. The numbers refer to clock positions, for example Tone 12 means tone knob is set to 12 o’clock. If a toggle was set to default position, it is omitted in the title; i.e. if UltraBASS was off, there would be no reference to it. A particular toggle is only mentioned if it was on when that sample was recorded unless it is a two position mode switch.
