1. Guitar Input accepts the output from your instrument by means of a shielded signal cable. This input signal to this jack is not attenuated and accommodates instruments with standard output signals. If your instrument has a strong output signal, use the Accordion Input
2. Accordion Input accepts the output from your instrument by means of a shielded signal cable. The signal to this jack is attenuated 6dB to accommodate instruments with stronger output signals.
3. Volume controls the overall output level of the amplifier. At lower volume settings the sound will be clean. As you push the volume higher and crank your guitar the sound becomes distorted
4. Tone controls the overall tonal character of the amplifier. Rotating the knob toward the “T” (“Treble”) increases the higher frequencies, giving a brighter, more “crisp” sound. Rotating the control towards the “B” (“Bass”) reduces the high frequencies, giving a darker, more “muffled” sound. The Tone control offers a cut or boost of 30dB at 4kHz.
5. Tremolo-Speed sets the rate at which the tremolo effect “vibrates.” The Tremolo-Intensity control (#6) must be turned up to hear the effects of this knob’s setting
6. Tremolo-Intensity sets the depth of the tremolo effect. For slow, smoother vibrato effects try the Intensity control at around 6 and the Speed control at 1. For the really wild sounds, crank the Intensity up towards 8 (or beyond) and go from there.
7. Reverb-Dimension controls the amount of reverberation applied to the signal. With the control at the “0” position there is no reverb applied; as the control is turned towards “10” the amount of
reverb increases accordingly
8. Power light illuminates (iridescent blue) when the amplifier is turned on. 9. Power switch is used to turn the amplifier on and off.
10. Power cord connects the amplifier to a suitable source of A.C. voltage. This is a grounded, three-wire cord and must be connected to a properly grounded outlet. DO NOT attempt to defeat the
ground connection of the power cord! If your amp was purchased outside of the United States, see the sticker next to the A.C. connector for its power ratings. Follow the above guidelines.
11,12. Power Tubes: 6L6 (2)
13. Power Amp Phase Splitter Tube: 12AX7A / 7025 (1)
14. Preamp Tube: 12AX7A / 7025 (1) Replace tubes ONLY with same types! Refer to pages 7 through 10 for important information about tubes and tube products.
15: Footswitch Jack is located up inside the amplifier, just past the cabinet’s covered back panel. Connect the supplied footswitch here for remote control of the Reverb and Tremolo on/off
