AnalogMan Sun Face List of Transistor Options GERMANIUM


The AnalogMan Sunface has always been a favourite among boutique Fuzz Face enthusiasts.  It is well built, sounds amazing and, relative to the cost of an original vintage example, quite a bargain.  There are numerous forum threads popping up on the topic of transistor choice lately (among other options) and it’s only heating up. With the return of the Red Dot NKT’s availability, the choice has become harder than ever…


To date, AnalogMan currently offers approximately 12 or so optional transistors in addition to the “Standard” Japanese Germanium 2SB175 (medium-high gain) available for fresh Sun Face builds.  A staggering amount, considering the importance fuzz fanatics place on having the “right” components in their pedals, especially when it comes to the transistors.  This stock option is anything but standard in the tone department, but with so many available transistors to “upgrade” to, it would be ideal to match your transistor to your style and fuzz requirements.  Low down dirty Blues that just hints at Fuzz?  Lo-Gain Germanium.  Biting raspy Fuzz for snarling 60’s Psychedelic Rock with a screaming edge to it?  High gain silicon is your choice.  Among the usual germanium and silicon camp lie many variations;  we will delve deeper into these soon.  The aim here is to prevent any potential option anxiety Sun Face purchasers face with so many available transistor options. Keep in mind that Analog Mike doesn’t seem to put out anything less than amazing, so there really are no bad transistor choices per se;  just some better suited to certain styles than others. Some users even find themselves exploring genres they previously didn’t because of how good some of the lower gain options are.

We will take an in depth look at each transistor later.  For a quick reference here is a chart with a few brief descriptions of each and of their attributes, both bad and good.  These have been cross referenced with AnalogMike’s website, but more importantly, they have been thoroughly verified by actual use.  In another post I will also list discrepancies, if any, from the AnalogMan descriptions, but for now here is the list.  The key here is to use this as a guide, and your ears as the judges in the actual evaluation. Since there is almost always some variation in transistors keep in mind that these findings may be different than yours.

Very smooth,
No grit (but not the point)
Usage Laid back tones, smokey
blues, even non-fuzz
overdrive tones
Non-descript fuzz,
not a defining tone as such,

CLASSIC Transistor,

Cons(Obviously) Won’t do High Gain
Priciest option (listed)
Usage Smooth refined fuzz, close to 
NKT275 so classic tones
Classic Fuzz Tones 60’s

*Found this to be higher gain than any others, but could just be this particular example ….

Transistor Red dot NKT-275  
GE General Electric
Black vintage
Medium (available High Gain)
Low, Med-High, &
High gain
ProsCheap, great standard choice, a
bit of character
cleans up well, Warm
and Crisp, smooth
ConsNot a lot of Bark, this particular
example was a bit dark
Seemed like it had a bit
more compression
than other Germaniums
Usage 70’s Fuzz, sits a bit better in
the mix than wooly transistors
Classic warm fuzz tones
Transistor TI/UK **
More to come…
ProsGreat NKT alternative (but distinct
enough to have both though!)
Known to be a bit brighter
than most Germaniums
ConsNot an NKT (but quickly
getting close to the same price!)
Usage Anywhere you want warm
Germanium tones but with a
bit more cut

** These have become really hot lately so keep an eye out for them at a relatively decent price online or otherwise. Again, they have just enough of their own voice to warrant having both an NKT loaded Sun Face and a TI/UK.
