Louis Electric Deltone Amp
The Deltone is a 6V6-based, 20 Watt, single 12" combo.
It is the result of requests from longstanding customers to build a black line
series to emulate the beautiful sounds of the pre-CBS blackface
amplifiers. The Deltone is a true
two-channel amp with two inputs for each channel. One channel offers a straight
sound and the other channel offers vibrato and reverb.
The Tremolo circuit was modified from the opto-coupled or
photo-cell tremolo circuit in the blackface amps and moved to a bias modulated
circuit. The Reverb circuit has also been altered from the 12AT7 driver tube to
a 12AU7. This change provides a more pleasing reverb sound to the ear.
The Normal channel of the Deltone has volume, treble and
bass. The Vibrato channel has volume, treble, middle, bass, reverb, speed, and
intensity. The original blackface deluxe amp did not have a middle control. The
middle control is a great addition as it provides more control for the player's
The Deltone comes standard with a 6V6 tube
configuration. The amp can accommodate a
6L6 configuration with 35 Watts of output power. An additional feature with the 6L6
configuration is a 4k/8k option. This
allows the player to simply switch the load to provide a cleaner or more
distorted sound. The 4k option provides
cleaner tones, while the 8k option will lower the wattage and provide quicker
mid-range break up.
