I’ve been seeing a few demos of the Electro-Harmonix Hot Tubes Nano Overdrive, and have been interested in this guy as well. The original Electro-Harmonix Hot Tubes was quite large (the bigger classic enclosures from back in the day – see pic), and it’s time to bring it back, but give it a smaller footprint – ala nano! I have to say, the original was pretty damn big!
The Hot Tubes is a CMOS overdrive and is built to the same original specifications as the original (I’m assuming components are generally the same). Hot Tubes has Volume and Overdrive controls as well as a tone circuit control. There is a toggle that will allow you to bypass the tone circuit all together, which is kind of nice dependent on your situation or needs.
Here is a great demo by GAK
