EQ1/EQ2

This switch allows you to choose between 2 completely 

different equalization setting.

 EQ1

 is a lower gain setting, with extended 

midrange and bass available when used in conjunction with the middle and 

bass controls as well as the deep switch. This setting is suitable for any style 

requiring a pure clean tone with a nice round bottom and plenty of 

headroom. 

EQ2 

is a higher gain setting , allowing a greater signal level to pass to the 

lead channel. This setting is suitable for any style requiring a clean to 

slightly distorted tone in clean mode , and more gain in the lead mode.

  9. 

INPUT GAIN

Adjusts the overall gain of the amplifier. Start with this 

control in the 12 o’clock position. Keep in mind that the amount of gain set 

here determines the signal level feeding the lead channel. Low gain settings 

of this control will require higher lead gain settings for the same amount of 

overdrive.

       10.

CLEAN CHANNEL MASTER VOLUME

Adjusts the output level of

the clean channel.

       11.

LEAD GAIN

Adjusts the input level (gain) of the lead channel.

At lower settings, a slightly overdriven tone can be achieved. 

As the control is adjusted clockwise, the overdrive effect increases.

12. 

LEAD MASTER

Adjusts the output level of the lead channel.

13. 

BYPASS SWITCH

This switch bypasses the tone controls, increasing both 

level and mid-range response.To enable foot switch control of this function, 

switch must be in the down position.

14.

LEAD CHANNEL SWITCH

Sends the instrument signal through the lead 

circuit, adding extra stages of gain to the  signal and enabling the lead gain 

and lead master controls. To enable foot switch control of this function, 

switch must be in the down position.

15.

  REVERB

Mixes the dry signal with a high quality spring-type

reverberation effect. This effect is defeated with the control in the full 

counterclockwise position.

16.

PRESENCE CONTROL

Adjusts the contour of high-frequency

response. The high frequency response will increase as you advance the 

control clockwise.

17.

STAND-BY SWITCH

The LTD is equipped with a three position STANDBY 

switch. In the center position, the amp is in STANDBY mode. In the "DOWN" 

position, the amp is operating with a low plate voltage setting. This is 

considered the LOW POWER mode. In the "UP" position, a higher plate 

voltage is supplied, and this is considered HIGH POWER mode. The difference 

in power between the 2 modes is approximately 25%, depending on tubes 

and class of operation.
