Gary Hurst Tonebender MKI

 

Like the last one, a bit of a pain but the Gary Hurst version is slightly more forgiving I believe.  Again don't forget to cut the trimmer legs that are shown over the -9V rail, there should be no connection there.  This is based on the original Gary Hurst MkI because the reissue was in reality a MkII.  Maybe Gary thought the MkI's are a pain as well! :o)

This one is verified

This is one of those effects that is a real pain in the arse to build, but one that many people still want.  It's such a pain to get the right transistors and get it to bias properly so I've included two trimpots to allow you a bit more fine tuning.  The left hand trimmer biases Q1, right hand biases Q3 and the Attack pot biases Q2.  Don't forget to cut the leg of the Q1 trimmer at the -9V rail.

One for the metal heads or those looking for a bit more gain.  The offboard wiring will be a bit of a pain though!
