Howdy, I'm building a wah pedal using the layout from this site but am having trouble getting it to work. No matter what way I try to wire it, I get no signal when it's switched on. I built an audio probe but i get noise at different volumes depending on where i touch so i'm confused on the aud...

I got some npn AC187 transistors and built both the Axis Face and the Mindbender over the holidays. I had the same problem with both in that I had to replace the 1K2 resistor with a 100K to get the voltage on the collector of Q2 to between 4 and 5V. (The voltage from the battery was measured at 9.2v). Has anyo...

1) What are the RIGHT voltages on the transistors pins? 2) Is it true that a Darlington pair works like a linear amplifier WITHOUT ANY DISTORTION or not? 3) What about removing (deleting) a 10 k from Q3 collector to ground?

phillip, thanks for the mod. i did it yesterday and it was very easy with the explanation you gave. this thing sound soo nice, mind you i only had it for about 5 minutes before i was already modding it. I was going to post saying that all my chips were working except for the Burr Brown you used. on further inv...

I went to my local Maplins (UK electronics chain) at Regent Road, Salford yesterday and they had a large basket of 9v 200mA wall warts for £1.49. These end in a tip positive mini jack meaning that they are perfect for old Electro Harmonics, DOD, Dunlop etc. pedals. I tried one with my big muff and old DOD p...

Hello my first post. The question I have is in regards to the DS1 mod, the chip that I have in my DS1 pedal is a BA726N, now in regards to what Phillip Bryant says on the mod page this mod works with the Mitsubishi M5223AL IC. So my question is are the chips the same replacement equivalen...

Gang, Is there a pedal out there that will simulate a Fuzz Face into a fully cranked Marshall, ala Jimi Hendrix

Hi Phillip, I made the Rangemaster clone from your schematics page and added some changes, like a input cap switch, LED and 1 meg pulldown resistors. This pedal sounds great. I just wanted to say thanks for the Info. BTW the other guitarist in my band said it was the best pedal he ever heard. LOL Now he w...

I built the axis wah and added a few othere changes and it rocks! I see no threads about it. Lets not be shy. Have a beer!

Tried my hand at the Scrambler. It's my second project after the 'Lune. It went together nicely but, when I plugged it in, had some weirdness issues. First, the texture knob only seemed to work when up halfway, otherwise, I got almost no sound. Secondly, the harder I played...

I am having some problems with the new Octavia I built from this site. I built the NPN version and it sounds good except that Im not getting much out of the two high strings. There is a huge difference in sound between some notes and others. It seems to be acting like a noise gate. The boost pot also doesnt ap...

I built a copy of the Foxey Lady 3 knob on stripboard and the sound is superb apart from a screech which occurs when the notes have died down. This occurs whether powered from battery or mains, using an amp or headphones and with 2 different guitars, it gets worse when nothing is plugged into the input soc...

Hi, can someone tell me how to get more "fuzz" out of my Dallas Arbiter Ge Fuzz Face??? Which resistors do I have to change??? -Philipp

Hi all, I've been building effects for a couple years by using existing artwork but would like to try building circuits from scratch by using perfboard. I figure this is a great way to really become familiar with circuits. I bought a few small pad-per-hole boards @ RadioSuck(did...

I noticed in the Tonebender info you recommend removing the resistor between the tone and vol pots to get a bit more volume. I'd say that this is a definite as I did this almost immediately after getting mine working. I tried it with 'Red Spot' germaniums first but it had very little volume and loa...

I started building the Axis wah and veered off a little as i leaned about different mods and ideas. I added the output buffer nd think i did that correct, and im adding a dcjack for power, and soon a cap selector switch. One problem i have noticed it the amount of noise/distortion like a "shhhhh" noise whe...

I have assembled all the parts to build a tube driver but I cannot find any info on how the pins are numbered on the socket for the tube. Can anyone suggest any links to suggest which way round the numbers go around it and where the origin is.

I was looking at trying to build a Hornby Skewes treble booster instead of plunking down $250 for a BSM HS but I'm a little but puzzled. On the BSM site they talk about how they choose their germanium transistors but the schematic on your site and over at GEO shows an FET... Was there another...
