3-Knob Tonebender Fuzz Most popular fuzz circuit besides the Fuzz Face is probably the Tonebender, which is also very simple but has 3 instead of 2 transistors. There have been different variations of the Tonebender Fuzz curcuit. The MKII has two knobs - volume and fuzz - and there are also 3-Knob versions which have an additional tone knob.    Tonebender is a Fuzz circuit that consists of 3 PNP germanium transistors. That means a voltage inverter is required if you want to run it with all your other pedals on a multi power supply. Otherwise you would need an own power supply only fo ..read more

Klon Centaur The original Klon Pedal is no longer produced and hence very expensive (+7000$ range and up). Thats why there are many clones of the Klon, many different DIY projects, for example the Kliche overdrive, the Kherion Klon from PCB Guitar mania and the AionFX refractor. Ive used the refractor project because it has some things ive wanted and I like: Fits into 125B Enclosure (maybe even a 1590B) PCB mounted pots Switch between buffered bypass and true bypass Circuit based on the original / KTR, same parts values etc I also liked the extra PCB for the 3PDT switch and that not much w ..read more

Tutorial: How to finish pedal enclosures with epoxy resin Ive been asked quite a few times, how i do my pedal enclosures. Thats why I decided to do a full tutorial on this blog, since its not only to show my work, but also to inspire, share knowledge and help others.  There are some ways to get designs on pedals, not only for labelling controls but also to make them look prettier. Most popular methods are using decals and finish them with enamel or epoxy resin, or use the edging techique. Ive tried most of them and epoxy resin works the best for me.  If you wanna use decals on pedals ..read more

Univibe Octavia Multieffect Pedal This build combines two pedals, which were made famous by Jimi Hendrix: The Univibe and the Tycobrahe Octavia Fuzz. I have used two madbean projects: The harbinger one for the univibe and the retrogade for the octavia. Ive put the octavia first in the signal chain. I just link to these two projects: https://www.madbeanpedals.com/projects/_folders/Octave/pdf/Retrograde2019.pdf https://www.madbeanpedals.com/projects/_folders/FilterMod/pdf/HarbingerOneFive.pdf Check out also my detailled build page of the univibe: https://fuzzypedals.blogspot.com/2014/10/build ..read more

Lets get Dirtbaby... The Dirtbaby is a recreation of the Deluxe Memory Man with the common delay chip PT2399. The DMM is Delay pedal by EHX which is also able to emulate a chorus / vibrato effect. The edge of U2 is using the DMM for a lot of rythm stuff (fe: U2 Song - Pride), so ive decided to build a dirtbaby (sidenote: Theres a new madbean project for a analog Memory Man now available: The Total Recall). All the parts are easy to obtain. The hardest part (for me) was the 2u2F NP (non polaric cap) The Pedal sounds really great, its very very versatile. If you like delay pedals, i strongly r ..read more

OCD Pedal The OCD (which stands for Obsessive Compulsive Drive) is an Overdrive Pedal developed by Fulltone.  Its a very famous pedal for its drive capabilities (also higher territories, almost distortion like) and its retaining the bass frequencies (a tube screamer kinda pedal is more mid-rangy)  The OCD is a very simple circuit and easy to build. Its a basically a standard op-amp drive circuit (like a tube screamer) with an enhanced tone stack. Additionally theres a switch between LP and HP. The HP mode adds additional resistor in parallel, which decreases the output resistance ..read more

The MXR Phase 90, probably the most popular Phaser Pedal (especially since Eddie Van Halen used it). The Phase 90 is a JFET base Phaser circuit. It uses 4 JFETs which needs to be matched to get proper phasing. For my build ive used a Madbean NomNom PCB and a matched JFET Quartett from Musikding (2n5952) You mach the JFETS by yourself too. Instructions for this are in the Madbean NomNom build doc.  All parts except the JFETs are very easy to obtain. For my build ive used following mods, which are the original does not have: Rate LED (which is also used as bypass LED) Feedback switch (i ..read more

Burns Buzzaround The Buzzaround is a Fuzz Pedal, which is based on the Germanium Tonebender, but has some variations. Soundwise its something between a Tonebender and a FuzzFace. It features 3 germanium transistors, the original features NKT213, which are very hard to obtain. Ive used AC125 for my build (ordered from musikding). The Buzzaround is a very simple circuit, and its very easy to build. Projects for the Buzzaround are: Madbean Bumblebee: Very good documentation (as always). Features an additional Volume knob. GuitarPCB FuzzyBee: Ive used this PCB for my build. Musikding also sells ..read more

The Deep Blue Delay is pedal by MadProfessor. Its a digital delay with smooth analog sound, based on the classic PT2399 chip. Its very standard, 3 knobs: One for delay time, one for repeats and one for the volume / mix level. This delay pedal is very expensive. Also it features no tap tempo. Since ive always wanted to do a tap tempo delay, i thought it was good idea to combine. Parts This is where ive got all the parts: PCB Deep Blue Delay = This is a Madbean Sea Urchin PCB, etched by Keef Gremillion You can order itin the Madbean Discontinued PCB section. PCB Tamp Tempo = Standard Taptati ..read more

SOV Overdrive The SOV Overdrive is Tube screamer circuit based OD pedal, with charge pump and some variations. Its developed by the company Free the tone - from japan. Matt schofield is using his custom made version of this pedal The Avalanche project from rullywow is a take on the SOV. great pcb Very transparent, loud and dynamic! Schematic   Drill Plan Find here the resized drill template of the build doc Drill Plan  My Build For my build ive used a red powder coated box, with waterslide + envirotex for finishing.
