Description

With the price of vintage HOT TUBES soaring, countless guitarists have requested that we re-issue our 1970s CMOS HOT TUBES. Weve done this using the exact same design and miniaturized it, too!

Volume and Overdrive let you go from a gentle rasp that caresses your notes to a full-blown gain monster with a powerhouse punch. Sculpt your sound with the Tone control, or take a detour around the tone circuit with the Tone On/Off switch. True bypass for a pristine signal chain.

FEATURES

CMOS overdrive
Sensitive to your touch and guitars volume
True Bypass
Tone bypass switch completely removes tone circuit
9 Volt battery included
Optional 9.6DC-200 power supply available

CONTROLS

OVERDRIVE Knob Controls the amount of input gain and distortion delivered by the Hot Tubes. As you turn OVERDRIVE clockwise, the distortion ranges from mild tube-like breakup to saturated distortion.

TONE Knob Creates a range of tones from warm bass to bright treble as the knob is turned clockwise.

VOL Knob Sets the output volume of the HOT TUBES.

TONE Switch When this switch is set to OFF, the HOT TUBES Tone knob is disabled, resulting in a more powerful, direct tone. When the TONE SWITCH is set to ON, the TONE KNOB behaves normally.

FOOTSWITCH and LED The footswitch selects whether the HOT TUBES is engaged or in true bypass mode. When the effect is engaged, the LED will be lit.

INPUT Jack This 1/4 jack is the audio input for the HOT TUBES. The input impedance is 100k.

AMP Jack This 1/4 jack is the audio output from the HOT TUBES. The output impedance depends on the VOLUME setting, ranging from 350 to 3k.

9V Power Jack The HOT TUBES can run off of a 9V battery or you can use an optional 9VDC AC Adapter capable of delivering at least 50mA to the 9V power jack. The AC Adapter must have a center negative plug. The battery may be left in or taken out when using an AC Adapter. The Hot Tubes draws 18mA at 9VDC.
