FRONT PANEL: INPUTS: First familiarize yourself with the layout of the front panel. Your SUBWAY amplifier is fitted with two INPUTS which are voiced individually for very different personalities and feel. BRIGHT would be the choice for all clean playing styles where sparkling highs are needed. - Page 7 CONTROLS: (Continued) TREBLE: As with most guitar amplifiers, the TREBLE control is the strongest of the three rotary tone controls. Its setting on the SUBWAY determines the blend and strength of the MIDDLE and BASS controls. Set high, it is the dominant control, minimizing the amount of MID and BASS that would be possible in the mix.

To confirm a noisy power tube, merely put the SUBWAY BLUES on STANDBY, remove it from its socket and turn it back on. It will cause no damage to run the SUBWAY BLUES briefly with one power tube missing. You may notice a slight background hum, however, as the push-pull becomes unbalanced. -
