There were two pedals called Hot Tubes. The first was a solid-state overdrive that, for some reason, EHX will not reissue, which is too bad, as I find it to be a good pedal. The second, which I have never heard, is completely different. It, like the English Muff’n, uses two tubes, but it somehow sounds different, in a way I cannot fathom. Both are currently out of production.
The reissue Hot Tubes with the 2 12ax7 valves is great for classic rock. The treble and bass knobs are a paracyclic filter, so they dont behave like a traditional eq section. They behave more like a wah, which allows for some mid rangey tones. If you like Ronson era Bowie, the Hot Tubes will appeal to you.
