I haven't heard anything about. In very general terms, I would say that probably every schematic.
Jack Orman's (AMZ) page. Keen's (GEO) page. Most of Justin. Philpott's Site is excellent (he has an effects feedback page). The schematics are listed by manufacturer or type or designer.

The Lava. Rim revisited. I realized the original Lava Rim sounds better. Lava Rim+! Here are my changes after a year. I think. it sounds great! Sound. samples available.
It's also very easy to. NPN transistors; the trimpots. You can mix NPN germanium transistors and silicon transistors. The trim pots let you use all types of transistors.
N5. 08. 8 for more distortion and gain. In addition. the 2nd transistor can use a MOSFET like the 2.
N7. 00. 0 or BS1. In addition. remove the diodes to really hear the MOSFET. Thanks to Jack. Orman for the tip on using a MOSFET for the 2nd transistor! F - > . 0. 1u. F. in parallel with the clipping diodes).
Hornet. - OK! High gain, high sustain, ANGRY. Minimalistic. design that can be .
Better watch. out cause the Hornet will sting The Rocket! Sound. sample available. The Hornet did not happen without the contributions. Alfonso Hermida. GFR, Gus Smalley, Jack Orman, R. G. Thank you guys! From Jack Orman. Since the supply of 2. N3. 88. A transistors have been depleted.
Parts Express, I thought I'd post a few alternate devicesthat they carry that can be used for F- F construction. Any of. the below parts should be suitable and are less than $1each.
The last one is spec- ed a little weak but would likely. The first one is a good sub for the 2.

The NTE1. 01 is another choice. NTE1. 01. html. 11/8/0. Small. Bear has a nice PNP version of the Hornet, check. Please try the 2. N3. 88. A. transistors as they are dirt cheap (1. I think). The 2. N5.
Mouser. The rest is pretty much Radio Shack or your local store. The . 0. 5u. F that I use I have found to be very. I have around the same bass as when the unit is bypassed. Many shades. of distortion will come out as you fool around and turn them. You can also. put the usual 5.
K pot at the input BEFORE the input cap as described. Technology. of the Fuzz Face - (GEO). Excellent article about the Fuzz Face. This will reduce your output level. I believe. the previous circuit I built on 1. The schematic works and is fine.
I didn't need. the bias pot for the 2nd one. More cleaning up and fixed a.
Jack cleaned up a few thing. Optional bias pot to stop gating. CMOS if you have the gating problem when notes are. You turn the pot until the gating is gone, measure. I have to point out that this is an advanced project. So many. things to keep track off.
In addition, I had to put in the bias. I just put one bias pot and connected a 1. Meg resistor. from each inverter input to the pot wiper. I ended with a 3. K. from 9. V to the 1. M resistors to inverter inputs, then a 5.
K resistor. to ground. The trim pot values are now listed. The revised schematic (revision 2) is now online. It was easy to create and gives very professional results. You can't miss them, they are the only. F caps on the entire board. In addition, I really mellowed.
F cap (two . 1u. F caps in parallel). F in the tone control. Remember that if you. F instead of the . F caps, you will. Basically two . 0. F caps. will give you a midrange heavy tone with some bass cut - nice.
Anything more will start giving you a smoother rounder. IC based distortion with FET booster. When the drive knob is turned all the way down and level. Goes from a hint of distortion to. The diode combination I chose produces a. I list a number of mods that you can. Put it on a proto board and mod it till it does.
Thanks to Jack Orman for helping with the design. FET booster on the end! Read the notes.. Shaka Braddah Mods by Doug Hammond. The. Shaka Express represents the top of the line Shaka for hi- gain. Step on this pedal and.
PCB. and Layout available from GEO. When the. drive is turned all the way down, you can a great good clean. Runs on 1. 8 volts (2 batteries) and has much less drive. Easy to build and sounds good. HV = higher. voltage. If you run it on 3. K. The circuit should go from soft clipping.
I believe the Shaka Braddah III. Shaka. Braddah III - OK! A. new version of the Shaka Braddah (based on a circuit by. Jack Orman) that sounds very good. Creamy and smooth. Smooth and warm at high. FET booster smoothing out the diodes.
Sound. sample available. Blake has another sound. SB3. In addition, when the drive settings. Each diode that you add will raise. Minibooster circuit. What this means is that you will hear more of the FETs.
In a similar vein, I suppose that. N9. 14 and 1. N4. Since I socketed my clipping section. I have tried different. ICs (RC4. 55. 8 and LF3.
LF3. 53 sounded different. I still like the sound of the TL0.
Try adding the . Fixed tone control, removed 1. K. trim etc.. It radically changes the sound. The pedal becomes more midrange, distortion is. More sustain at the expense of fidelity. The 1. 00. K trimmer loads. The new schematic reflects this change. On R. G.'s. board (which all of you should purchase), here.
A, not bad. I think you will find that. Shaka III circuit is extremely versatile and adapts to different.
The pedal sounds very different when used with. This probably explains. K resistor. is there. This arrangement sounds extremely. Wire 2 of these and reverse them in polarity when. Make 2 of these and then use them as diodes in the. Shaka III. This trimpot allows you.
The diode array tested at ~. Very nice.. Even. I'm going to. try some 1. N9. 14 and 1. N4. I realized I am able to mount the diodes. I did like. the sound of his mods.
I find that the Rat circuit seems to produce. The Booster 2. 5is the next generation. Booster 2 designed by Jack Orman. I refined the circuit.
Jack put in his Mini- Tiubes pedal. The. result is a stunning overdrive that has 9. Mini- Tubes with about 1/3 of the complexity.
A great. pedal, I am still enjoying mine. Also check out the Sweet. Thing, which is the Booster 2. Doug. Hammond's mods. Another excellent variation; this one is. Coming soon: Boost.
Sound. sample available. Hot Fuzz. - My take on the Colorsound Tone Bender Professional Mark. II with the Sweet Thing tone control. I'm still working on. Sound. sample available.
Apollo. Attenuators. Bell. Bespeco. Blackbox DIYBixonic. Boss. I. would purchase all Boss pedals because most of them are very complicated. Carlin. Colorsound (Sola Sound)Fuzz(Stellan's. Schematics)Overdriver.
OK! I like this pedal! Initially. designed to do clean boost.
Boy does it BOOST! To control the. gain and make it more like a distortion pedal, put a 1. K or 1. 00. K. volume pot at the end of the circuit, that way you now have a. Verified 8/9/9. 8.
Has a Big Muff/Sonic. Lots of gain. An interesting sound, It seems like. I can still hear the original guitar sound in the output like.
Look at. schematic.. Now look at the Jumbo. Tone Bender.. This is. There have always been some doubts about the schematic. The schematics posted by RG are pretty close, the only differences. ALL pots are 1. 00k not 2.
Mg (it appears the Yardbox. The resister from Q2 to earth is 3.
K not 3. 3k. 3. The capacitor that parallels the 3. On my unit there is a 2. The Transistors are all unmarked metal can. Germanium. The can has a narrow ridge around it about. One more thing, I've always believed that. This one however is dated inside 2.
March 1. 97. 4, so perhaps it is a later design after all or at least. The case is a very slightly shallower. Well there it is. I never thought I'd see one of these in the. OK! Tone Bender Professional Mark II.
Check out the various Bender variations. Check it out! Coron. Craig Anderton. Dale Van. Zile. Dallas. Rangemaster - OK! Check out R. G. Dan Armstrong said that MXR copied this circuit. Distortion+. He said they copied it line for line.
Last I knew, the Distortion+ does not. Doug has worked a while on this design and it promises.
All the good attributes of the Shaka Braddah. III have been retained with improvements. Here is the PCB. A Shaka with attitude+!
Try lower h. FE transistors - like 1. Ed Rembold suggests Q1 base to ground. K. OK! Notes: According to Jack.
Orman, . You have to feedback from the output to the. Schmitt trigger).
