The Gary Hurst MKI is the 1st incarnation of the Tonebender! Originally housed in a wooden enclosure with a 3 transistor circuit and hand assembled by Hurst himself. He was asked by a British session guitarist to improve upon the Maestro Fuzztone by adding more sustain. He soon switched to the gold finished folded metal enclosure. Solasound then took over production even using the same style enclosure. Then for whatever reason, they released the Tonebender MK1.5 circuit with only 2 transistors. This was housed in a silver MKII style enclosure. This was the pedal used as the basis for the Colorsound/Macari MKII RI. This circuit was soon replaced with the 3 transistor MKII. The reissue Hurst Tonebenders you see from Musicground and Ebay are essentially 3 transistor MKII circuits and voiced closer to a Supa Fuzz.The Gary Hurst MKI was a reissue of the original Tone Bender (made by Sola Sound, Gary Hurst). And the reissue was a two transistor version not a three. The three transistor housing, gold folded, was also used for the later two transistor for a very short period, MK1.5 not to be confused with the reissue two transistor as they are not the same. If it is the old gold folded MKI housing but does not sound like a Fuzztone it is most likely a transition box with the MK1.5 two transistor circuit in it. So it's possible they're claiming that they used this version? I know that the Yardbirds used all sorts of fuzzes over the years depending on who was at the helm, I'm not sure about Ronson.
The Gary Hurst pedal was refurring to is the reissue of the same name.The Gary Hurst MKI is the 1st incarnation of the Tonebender!
And just prior to the MKII style housing some of those made it in the gold folded housing.Then for whatever reason, they released the Tonebender MK1.5 circuit with only 2 transistors.This was housed in a silver MKII style enclosure
I've read this to. I don't know how he improved on it they sound almost identical. Maybe you get all that sustain from the 9 volt battery over AA's?He was asked by a British session guitarist to improve upon the Maestro Fuzztone by adding more sustain.
