Rare Sunface Fuzz Pedal with NKT-275 White Dot, w/sundial and on/off volume pot. I have owned this pedal for years and has sat most of that time in it's box, have never gigged it because I had a KOT, and fuzz was never really needed for the stuff I play. It's an amazing sounding pedal and have loved playing with it the last few weeks while deciding to sell. The way it cleans up when backing off the volume sounds better than any boost or overdrive pedal I have owned and wish I had realised this sooner! I will no doubt regret selling it. Keen to move it on so MAKE ME AN OFFER!

The Analog Man Sun Face custom built fuzz pedal. This is higher quality than almost any other fuzzface clone you will find. Available with several transistor choices and many, many options.

In July, 2002 we started offering a NOS NKT-275 version of the Sun Face, using New Old Stock British Newmarket 1960s NKT-275 transistors. These were the actual transistors used in the original $expensive germanium fuzzfaces, not the skinny US made copies used in the new fuzzfaces since the 1990s (which look and sound totally different). You can take a peek into one of our NKT-loaded pedals on the left. It also includes an additional BIAS trim pot inside to set the exact bias on these transistors, for the ultimate sound. The Blue trim pot is for Bias, which should not need adjustment often, while the big White one is the CLEAN (input adjustment) knob. The BIAS pot really helps if you play at different temperatures. You can turn it down a bit at higher temperatures, and up a bit at lower temperatures, to keep the transistors happy and sounding best at their SWEET SPOT which is about 5 volts. The Sunface manual has more information on adjusting this. The bias control is more often found on the outside of our Sunface pedals as the SUN DIAL knob.

The sound of these NKT275 transistors is quite similar to the other types of germanium transistors that we use. But the NKT275s have less fuzz, and less high end fizziness. They have a deeper tone and clean up better than any other transistor. If you turn down the volume on your guitar, the NKT275 sound will be totally, sparkly clean without any fuzz remnants. Normally, NKT275 transistors are not high gain, that is why they clean up so well and are so smooth sounding. However we did have some high gain NKTs we have sorted out over the years, out of the same batch. If you don't need a fuzz that can get TOTALLY clean when you back the guitar down just a few numbers, the NKT275 is probably not for you. They are also tough to use with humbuckers, easily get lost in the mix in a band situation unless you play REALLY loud.

We sold out our first batch of NKT-275 transistors with red dots (totally authentic, came in little "cigarette packs" as seen above) in just a few months, but found more. Those early 1970s "white dot" NKT275s are the same size but don't look exactly the same. They have less (almost no!) leakage, and sound a little less dark, with better high end definition. They are from a military supplier in the UK and were tested to a NATO spec. These have white dots instead of red dots, signifying the military spec. They are not the skinny USA reproduction NKTs used in the new fuzzfaces or in some other fuzzface clones. When I retested them here, 95% of them worked perfectly unlike the last batch which was about 25% dead. The SUNFACE reviewed by Guitar Player magazine had the older red dot NKTs, while the one reviewed by TONEQUEST magazine had the newer ones. We ran out of the white dot NKTs in 2011 and are saving some just for repairs. We doubt we will be able to get more in, as all the ones we have gotten in the last decade were fakes parts that others already tested and rejected so we never used them.
