Portable Bass Products

Simone For Bass

Simone in the studio

Simone is about keeping your sound with you no matter where you find yourself. Small enough to fit in a backpack. Four tubes (valves) let you choose your tone and playing characteristics. The DI output uses the same Cinemag transformer used in the Monique. 

Simone Preamp

Simone on the floor

Simone is 7" (18.5cm) wide, 4 1/2" (11.5cm) deep, and 3 3/4" (8.5cm) tall. She weighs 3 pounds (1.4K). Ready to drive your amplifier from the front input or the aux in output. It doesn't get much easier. 

Simone 500 watts

500 Watts on the pedal board

The Simone 500 watt bass amp is designed to give us a true 500 watts into 4 ohms. You have 2 Powercon Speaker outputs in parallel. Optimized for 4 ohms, the Simone 500  is comfortable at 2 ohms and 8 ohms. No fan is required due to the all-aluminum chassis design. 

Classic Preamps

Hand made bamboo enclosure for Monique

Monique in Bamboo

The electronics, the sound, is exactly the same as the Dove Cage. The only difference is the enclosure. This Bamboo (wonderfully renewable wood) is hand made and it is hand finished by Jule!

Dove Cage - Gorgeous sound

Dove Cage Monique

First in the Monique product tree. Smooth powerful all tube bass cuts through the mix like you (and your engineer) won't believe.
On stage or in the studio, Monique will make you smile!

700 Watt Monique
