This setup is a “vestigial tail” from the original amplifier which was a modified 5C3 Deluxe with three inputs.  We used the same 
labeling, but proved high and low inputs for each channel for added flexibility. 
 

INST VOLUME 

adjusts the signal strength in the INST channel of the Tweedle Dee.  Again, this is for the brighter, tighter 

channel.  Think of it as a traditional volume control in non-master volume amplifiers. 
 

MIC VOLUME 

adjusts the signal strength in the MIC channel of the Tweedle Dee.  Again, this is for the fatter, darker channel. 

Think of it as a traditional volume control in non-master volume amplifiers. 

 

NOTE – experiment with jumpering both channels together and various combinations of INST and MIC volumes for a wide 
palate of guitar tones!

 

 

TONE

 adjusts the frequency balance for both channels.  At counter-clockwise settings, the tone has more bottom end and less 

treble.  At clockwise settings, the tone has less bottom end and more treble. 
 

NOTE – various combinations of TONE, and individual channel VOLUME controls will provide the greatest flexibility in a 
deceptively simple amplifier! 

 

INDICATOR 

will illuminate when the Tweedle Dee is powered by turning the front panel POWER toggle switch to the ON 

position.  If INDICATOR does not turn on, check your power cable connections, and then the fuses on the rear of the unit. 
 

POWER (ON / OFF) 

two-way toggle switch

 

powers the Tweedle Dee on and off.  With the toggle switch in the UP position, the 

Tweedle Dee is ON.  In the DOWN position, the amplifier is OFF. 
 

STANDBY (ON / OFF) 

applies high voltage to the vacuum tube anodes (and screen grids) during use of the Tweedle Dee. With 

the toggle switch in the UP position, the amplifier is operational.  In the DOWN position, the Tweedle Dee is in STANDBY 
mode.
