NOTE - Just like the original "Jose mods", these different modes will impact the taper response of the MASTER control. In
other words, some settings might seem louder than others. In reality, equal volumes are happening sooner or later on the
control. The '60s mod hits stage volume soonest, and the Modern voicing hits stage volumes latest. Don't be afraid to turn up
the MASTER control in the '80s and Modern modes!
TREBLE adjusts the high frequency response in Channel 1.
MIDRANGE adjusts the mid frequency response in Channel 1.
BASS adjusts low frequencies in Channel 1.
PRESENCE adjusts the high frequency response of the power amplifier using negative feedback. Use this control to add
sparkle and clarity to your tone.
DEEP adjusts the low frequency response of the power amplifier using negative feedback. Use this control to add depth,
punch, and "thump" to your tone. Turning this control all the way counter-clockwise defeats this control and removes it from the
power amp.
INDICATOR will illuminate when SOY OTS is powered by turning the rear panel MAINS toggle switch to the ON position. If
INDICATOR does not turn on, check your power cable connections, and then the 2A slow-blow fuse on the rear of the unit.
STANDBY applies high voltage to the vacuum tube anodes (and screen grids) during use of the SOY. To ensure long tube life,
first power the unit on with the toggle switch in STANDBY position for approximately 30 seconds. Then place switch upward to
ON position to use the SOY. With the toggle switch in the UP position, the SOY is in operate mode. In the DOWN position, the
SOY is in standby mode.
POWER two-way toggle switch powers the SOY on and off. With the toggle switch in the UP position, the SOY is ON. In the
DOWN position, the SOY is OFF.
