I notice that there is one What’s a Crying Tone answer on the poll. So here is a quote from one of the Forum’s CT topic posts:

“Here’s a photo of my Crying Tone / Volume Pedal family. (Posted on Pan Pedal as well). Posted here because I picked up one of the Volume Pedals, the Crying Tone and one of the Muff Fuzz Crying Tones over the last months on eBay. A good example of what is available out there at the moment.(The others I bought at the time of issue and used (still use) when playing gigs and in the studio)”

As some stalwart EHX forum members have pointed out, there were other pedals in this format, for example, the Pan Pedal, the Hotfoot, the Bad Stone Phaser, the Octave Multiplexer, the Queen Triggered Wah…..and the CT housing would indeed be really practical for a whole range of effect pedals, with volume/modulation etc able to be controlled directly by use of the treadle.

Yes, the value aspect has taken on importance nowadays for vintage EHX pedals, as it has for vintage guitars, but even today I still mod my gear, including ny Electravibe and guitars, whenever I feel it will help with the sound and/or performance I am looking for. Sometimes it works, sometimes it doesn’t, but the music aspect always takes priority.
….colour-wise I like red, green and amber LEDs. I also find blue LEDs turn me off (!) for some reason, though I can’t imagine why.
