The TUBER product line provides vacuum tube-based analog signal processing in Stomp Box Pedal packages. Distortion and Tremolo pedals are currently available.
Common to all TUBER products, the internal step-up voltage supply drives the tube plates at more than 200 volts - much like a typical preamp tube in a tube-based guitar amp. A 12 vac adapter is provided. A separate internal regulated dc voltage supply provides power to the tube filaments to ensure quiet circuit operation. High input impedance and a buffered, low impedance output connection means TUBER products will play well with the other devices in your pedal chain and your recording hardware. TUBER circuit boards are manufactured in a state of the art factory employing ISO9001 inspection standards.
TUBER Tremolo (FSTRM) provides a vacuum tube based analog tremolo effect in a Stomp Box/Pedal package. A single footswitch provides for "on" or " bypass" modes. Two on-board 12AX7 vacuum tubes provide circuit functionality, resulting in a lush optically coupled tremolo modulation of your guitar signal. The FSTRM control panel also includes a single pot tone control and an output level control. Input and output jacks are located on the rear panel. The FSTRM PCB layers include grounded copper pours for quiet operation.
