Just build a King Nothing and it worked first time and is sounding quite cool. Somehow the tone control has a very limited range and doesn't seem to do much. Is this as expected @vigilante398? Can this be improved? Here’s the internals: Cap at the top which is on it's side is a 4n7

I'm planning to build the King Nothing the coming weeks. I've seen quite some build reports here and I want to ask which FET the forum members used for their build and if they measured bias or if there was an issue with the bias? Does the FET require specific idss/VP values or does it not...

I recently finished 2 Boneyard builds created by our mastermind @Chuck D. Bones! Really like both of these builds a lot. Left is another green topped Mojito which is a great modified BJ circuit and inspired by @HamishR made in a nice PCB by @Robert. I’m glad you create and make these because I...

I just finished these 7 green topped builds, mostly with copper knobs. Top 4 from left to right (in the above picture): - Exar OD build using a Musikding Screamer PCB. Designed for side jacks so I used normal pots with wires and some velcro to position the PCB. Overall a nice version of the...

I’ve posted an issue with the God City TTTSNB EQs PCB last week relating to the LT1054. I’ve replaced the burnt out LT1054 with a new one and the build is working again. The left side EQ (Mesa 5-band) always worked well without issues. The right side 3 band semi-parametric EQ has had issues...

I'm building the TTTSNB from God City Instruments https://www.godcityinstruments.com/collections/diy-pcbs/products/n-e-w-the-thing-that-should-not-be. I'm placing both PCBs in seperate BB enclosures. I've already finished the Preamp but there's an issue with the dual EQ pedal. I've populated it...

I’ve been experimenting with a routing setup that produces noise into the signal that I haven’t been able to solve. I tried a Lehle D.loop SGOS in which I routed 3 loops: one containing a Tonex pedal, one containing a UAFX Lion 68 and one containing a Bogner Ecstasy 101B amp head going into a...

I’ve been reading about the transistors used in an 808. I’ve build a Dwarven Hammer (Prevision Drive) using 2n3904s. Some mention on other forums that a 2n5088/2n5089 combo or 2n5088 (Aion used these) or 2n5089 pairs are preferred, 2n5089 having the lowest noise. BC550 can also be a good one...

Curious about differences and response of the Draco vs Boogie Monster. Read on the forum that it’s too mid scooped? Anyone try modding the mids behavior? And how do these compare to the Abasi Pathos and Wrectifier? Fet based vs opamp based. Also interested if someone build the around 20 years...

Cool build and great, amp like sounding pedal. Timmy on steroids. Boosts well with the gain to minimum and gradually adds overdrive up to quite some distortion when increasing the gain. The mids pot is where the zorks are. ;) With mids to minimum it’s flat but increasing it adds a very pleasant...

Nice build and great sounding vibe, no need to buy one from JHS when you can build it yourself to your own liking. I had a tiny issue with a broken trace I found when measuring continuity on the PCBs. The trace between the 1n5817 and 47uf wasn’t working but when I made a small bridge from the...

I’ve acquired 2n5088s for an Electrovibe Mini I’m going to build. I noticed that most measure around 718 HFE but some are above 800, some are around 616 and one is 477. This was with a cheap measuring device. Does the HFE and leakage matter in this circuit? EDIT: Measured them again with my...

I should receive the Souldrive PCB tomorrow or Friday and got some 1n916 diodes for the clipping section, should be similar to 1n4148 probably. I also want to try some higher mV diodes like BA282/482 or MA856. Might open up the pedal a bit more so I’ll give those a try and see how they respond...

Can someone help me with how to create a veroboard design from the schematic below? This is the trimpot PCB for an Ilitch backplate denoiser coil that I'd like to create on veroboard. On the left the BPNCS (back plate noise coil) is shown which has a resistance of about 335-360 ohm.

I’m trying to better understand why biasing sometimes works and sometimes doesn’t work. I have a practical question about the Sandspur / Sunflower PCBs. I’m trying to use 2n1308 NPN germaniums in the Sandspur and noticed that the collector voltage of Q2 can’t get below around 5,5V. Bias and...

I’m building a number of fuzz faces with the Sunflower and Sandspur PCBs and the Solaris and Epsilon AION PCBs. Also the Tactical Fuzz. The clean control of the Sunflower/Sandspur is 50k (I make it externally controllable) and the AION ones use B 250k pots. Both seem to work fine but I was...

I'm using 2 Ilitch noise coil solutions, one with a backplate and another one routed underneath the pickguard. This noise coil has a resistance of around 350k (for standard) which works for standard output single coils. Ilitch includes a small PCB with 2 trimpots and a few SMD caps to dial in...

I own an original Maxon SD-9 and I’m interested to experiment with a number of PCBs which are similar. This thread is to share insights and mod experiences. I’m going to build an AION Meteor (Mods from the SD9M (mids) and a clipping switch) and the PPCB Samurai (based on Way Huge Geisha Drive)...

I build a Clandestine preamp yesterday and its quite a nice pedal. I got around 23v on R101 and I set the bias to around 13.9v (just right of center of the trimpot) which is about 60%. The pedal operates well and the 3 EQ presets work nicely. I noticed something very peculiar which I've...

I recently build quite some pedals using Robert’s superb PCBs. Here’s 10 of them. ;) Left to right: - Abider - Fordoble - Mystery Meat - Duocast Left to right: - Cattle Driver - General Tso’s - Paragon Mini - Modus Operandi - Cobbler - Special overdrive I will detail some of them below...
