Wren and Cuff takes two hand-matched BC108 silicon transistors selected for specific gains, super-quiet metal film resistors, and add smoothing capacitors to tame spiky highs and eliminate squealing at higher volumes, and that's only the start.
Don't like the low output on a traditional FF? Fixed it. All the volume you could ever want or need.
Don't like the way that a traditional FF fuzz knob is only useful at the last end of the knob? We've added a reverse-log potentiometer that widens that range and let's you dial things in just right.
Mullard “tropical fish” out-cap with increased value to allow more lows to come through. Also, Mullard tropical fish caps just look damn cool.
Custom “You” knob functions as a low-cut to reduce some of the low-end squash, letting you dial things in just right for "you". This is a simple but fantastic mod that gives an incredible amount of versatility.
