Search for "fuzz by macha工房 MP42b x 2SB175 re-recording" Power: DC 9V center negative (Battery operation not possible) Knobs: Left vol, Right gain Uses 2SB175, which was used as a substitute for NKT275 in analogman sunface and is becoming difficult to obtain. This fuzz was created with the sound of a Fuzz Factory used as a normal fuzz in mind. It's the most satisfyingly complete fuzz I've made so far. In a word, it's an easy-to-use Fuzz Face-like fuzz. It features two germanium transistors: MP42b and 2SB175. After experimenting with various transistor combinations and measuring hfe values, this combination was chosen. Personally, I feel it's a combination that rivals AC128 and 2N404. Other parts also have a vintage tendency. Many general fuzzes become too boomy and lose chord definition, but this fuzz has a distortion-like bite, making it an easy-to-use fuzz. The responsiveness to the guitar's volume knob is also reproduced, allowing for clean, bell-like tones and crunch. The appearance is inspired by the Fuzz Face, finished in matte red lacquer. There are a few small paint chips. A trimmer potentiometer is attached to the board for the comp knob, so please adjust it to your preferred position. As long as you don't overdo it, it sounds good in basically any position. It's generally recommended to use it with a slightly overdriven amp. Operation and sound output have been confirmed. Although "new, unused" is selected for the condition, this is based on the criteria that it has not been used after production. Please understand that this is a handmade product, and there is no evidence that the original circuit is equivalent. We are careful with thorough checks and packaging, but please understand that all measurements and checks for dirt are done by eye, so there may be errors or oversights regarding dirt. fuzz face fuzz factory
