TUBER

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. First TUBER pedals were powered by a 12vac supply,.  A 12 vac adapter is provided. An internal, regulated dc voltage supply provides power to the tube filaments and  ensures quiet circuit operation. Current TUBER pedals have been redesigned for 12vdc operation and take advantage of current pedal board power supplies that offer 12 vdc taps.  1 amp is required to properly power TUBER pedals. If your pedal board power supply can't satisfy this requirement, a 12 vdc wall wart is required. High input impedance and a buffered, low impedance output connection means TUBER pedals will play well with the other devices in your pedal  chain and your recording hardware.  TUBER circuit board layers include grounded copper pours to ensure quiet operation. All TUBER circuit boards are manufactured in a state of the art factory employing ISO9001 inspection standards.  Please check out the audio clips on the Media Page.

• TUBER Pedals:

TUBER FS1C :

The original TUBER - a single  channel, vacuum tube based  distortion pedal with separate drive and output level controls and a very responsive two-knob James-like tone stack offering separate treble and bass control. Foot Switches provide for "on" or " bypass" modes . Two on-board vacuum tubes provide plenty of drive and volume. The 12AX7 preamp tube is the design baseline but the tube bay will accept any 12A_7 tube so users can mix and match tube gains to paint their own tone picture. You can set up any TUBER  as a clean boost or high saturation monster. TUBER PCB layers include grounded copper pours for quiet operation.

TUBER SLO:

TUBER SLO is available in 12vac (Version 1) and 12vdc (Version 2) power supply variants. Single channel  operation includes separate drive and output level controls and a FMV (Fender Marshal Vox)  tone stack offering separate treble , bass and middle frequency control. This is the vacuum tube  pedal for players who like  a mid scoop option - closer to Marshall 2203/4 and Soldano cold clipper tones.  A Foot Switch provides for "on" or

" true bypass" modes.

TUBER Tremolo :

TUBER Tremolo (FSTRM)  version 1 is powered by a 12 vac adapter. TUBER Tremolo provides a vacuum tube based analog tremolo effect. A single footswitch provides for "on" or " true bypass" modes. Two on-board 12AX7 vacuum tubes provide circuit functionality, - 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.  Version 2 of the TUBER Tremolo is in development. Version 2 will be non optical  and will have a 12vdc power supply requirement.
