The SineWave Continuum Stage

Bringing the tone!

Controls and Specs

The Continuum and the Continuum Stage amplifiers are the culmination of building clean style amps for over two decades. These amplifiers DNA are firmly rooted in a mix of classic “Black Face” and “D-Style” front end topology and voicing. Over the last 25 years the layout, build, and parts choice have been continually fine-tuned to arrive at the designs that are being built today. The core idea of these designs is to provide the player with a very familiar voicing and feel. One that will help showcase the guitar, pedals, and players ability to create music. Both versions have the same front end but then differ when it comes to the phase inverter and power section.

The Continuum standard is more in line with a traditional “Black Face” amplifier with a standard phase inverter and power section. It will feel and play like that classic amplifier and offer more saturation at the start of the power section. This design has slightly more bounce and sag on the note.

The Continuum Stage has that same front end of its counter part but then drastically changes when it gets to the phase inverter. It shifts to a higher power or “Hi-Fi’ topology offering more clean headroom and punch to the power tubes. This amp is very much more in the vein of the classic “D-Style SSS” type amps.  Extended low-end response and shoulder on the note are combined with a more immediate attack from the fret-board.

    EQ

    The front end EQ section is extremely balanced and will allow the player to achieve the correct levels in the bedroom, studio, or the stage while adding more options for any guitar/pickup arrangement, rooms, or just wanting to play at lower levels. 3 toggle switches to extend each frequency range.

    CONTOUR

    The Contour control is a very familiar cut circuit that will reduce the higher frequency ranges of the output signal as it hits the power stage.

    POWER

    The Power section will be designed around the needs and desires of the player. The core amp was originally built around 6L6/7581A or comparable tube types. However the amp can be adjusted to fit any production tube type.

    EFFECTS LOOP

    The passive loop offers a basic interface for time based effects, post preamp. The Master Volume acts as a send to loop and requires a balanced, buffered setup with level control as it integrates back in to the amp.

SIGNAL STRENGTH

  • The Signal Strength circuit was created to optimize the front end of the amp and how it integrates into the back end of the preamp.  This circuit offers two options:

  • The high is more akin to an old vintage blackface in the way the bass and gain overpower the rest of the amp. This will instantly feel a bit more “old school” and will also offer more gain and volume. Overall headroom on the preamp side will be lower in this mode.

  • The Low is more modern and will decrease the amount of “harsh” or harmonic distortion that most vintage amps have. It will also help smooth out the signal if overdriven from pedals. There will be more note separation in this mode and the lower amount of gain will allow for more preamp headroom.

REVERB

The tube driven reverb is a versatile circuit that will allow a subtle reverb or a lush, washed out reverb. It was designed to mix with the dry signal in a very non-obtrusive way. The Send and Return controls allow the user to dial in exactly how the reverb signal is amplified and mixed with the dry signal.

REVERB EQ

The Reverb EQ is a three way switch that changes the frequency range of the mixed reverb signal.

  • Neutral – This is the normal mode and is considered neutral in both voicing and feel.

  • Bright – This setting will increase all the highs in the wet signal. Making the mix splashier.

  • Dark – This setting will decrease all the highs and mellow out the reverb signal.
