HOT TUBES
Congratulations on your purchase of the Hot Tubes overdrive, a faithful reissue of the original 1970s Electro-Harmonix classic, now in a compact pedalboard-friendly enclosure. Since its initial release in 1978, countless musicians have prized the scorching tube amp simulation the Hot Tubes delivers. They consider the original Hot Tubes to be indispensable, so it is rarely available on the vintage market. Now there is no need to search. The Hot Tubes reissue gives you the exact same tone and drives as the original.

When the effect is engaged, the LED will be lit.INPUT Jack – This ¼” jack is the audio input for the HOT TUBES. The input impedance is 100kΩ.AMP Jack – This ¼” jack is the audio output from the HOT TUBES. The output impedance depends on the VOLUME setting, ranging from 350Ω to 3kΩ.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.
