Might be worht considering the 'Build your own clone' Mark II Tonebender. My one sounds excellent, comes with NOS transisters, excellent components, easy to put together (as long as you can solder) and costs about £60. I have a Fuzz Factory which sounds amazing and is very versitile but takes me about 5 hours to dial in. I also have a little big muff but the Tonebender has much better tone. So on balance the Tonebender is the best fuzz I have owned.
