[. . . ] An obvious choice for an external speaker would be the Classic @ 115E which uses the same speaker in a larger cabinet.

The speed control determines the rate at which the signal is modulated. This control varies the speed of the Tremolo master oscillator and should provide any speed desired for modern music. Clockwise rotation of the speed control increases the speed of the modulation of the tremolo. The intensity control is used to vary the amount of amplitude modulation of the clean signal. The final level adjustment should be made after the desired sound has been achieved. Be sure to use a high-quality shielded cable to connect the guitar to the amplifier. When using the remote footswitch, always insert the plug fully (second click) to ensure proper operation. Connect only to a power supply of the type marked on the unit adjacent to the power supply cord. For more information on grounding, write for our free booklet "Shock Hazard and Grounding.
