Gotten a few requests for this one and I finally got around to doing it. It's a bit of a hodge-podge–3 dual opamps, a hex inverter, and a JFET mu-amp array. Definitely not fitting this in a 1590B, but will fit nicely in a 1590BB with the pots board mounted. Info and schematic here.

Tone Kontrol (TC) adalah rangkaian untuk mengatur frekuensi yang ingin dikuatkan pada penguat amplifier. Hasilnya bisa melakukan pengaturan penguatan suara yang akan dikuatkan sehingga menghasilkan suara yang bagus(tergantung kesukaan user). Banyak sekali macam rangkaian tone kontrol, berikut contohnya: Bagian 1. Tone Control Pasif sangat mudah dibuat, menggunakan komponen yang sedikit, tidak ada noise(hump, dsb). tetapi mempunyai satu kekurangan yaitu melemahkan suara input sehingga hasil suara akhri terdengar lebih kecil dibanding sebelum menggunakan TC. Walaupun begitu cukub baik untuk awalan belajar merakit rangkaian elektronik apalagi karena menggunakan sedikit komponen sehingga murah. Catatan tone kontrol ini mono. daftar komponen: C1: 100n C2: 10n C3: 1n C4: 10n C5: 10uF/10V R1: 10K R2: 1K R3: 10K Potensio 100K semua kapasitor yang digunakan adalah milar kecuali C5. Input disambung dengan jack 3.5mm sedangkan output disambungkan ke input ampli. Karena jack 3.5mm stereo R dan L digabung supaya menjadi mono baru disambung ke tone kontrol. link terkain: memasang Tone Kontrol Pasif dengan ampli TDA2822 Bagian 2. Tone Control Aktif merupakan tone kontrol yang ditambah penguatan kecil sehingga rugi-rugi(pelemahan) yang dihasilkan rangkaian bisa seperti tidak ada. penguatan tone kontrol bisa dibuat dari rangkaian transistor atau OpAmp. berbeda dengan TC pasif, TC aktif perlu sumber tegangan untuk menghidupkan transistor atau OpAmp. gambar skema rangkaian TC aktif gambar jalur PCB TC Daftar Komponen : Nama Komponen Proteus Eagle C1: 1u/16V C2: 47u/16V C3: 47n C4: 1n C5: 47u/16V C6: 3n3 C7: 10n R1: 5k6 R2,R5: 56k R3,R4: 8k2 R6,R7,R9,R10: 4k7 R8: 10k R11: 56k potensio: 50k IC: 4558 ELEC-RAD10 ELEC-RAD10 CAP55M CAP55M ELEC-RAD10 CAP55M CAP55M RES40 RES40 RES40 RES40 RES50 RES40 - DIL08 catatan: potensio pada contoh layout diatas tidak tersedia di proteus. Harus membuat sendiri, Sementara bisa diganti dengan "P1". P1 adalah footprint untukk transistor, tetapi mempunyai ukuran yang kaki yang sama dengan potensio. - OpAmp 4558 pada gambar skema diatas terdapat gambar segitiga dengan tanda + dan - didalamnya, itu merupakan simbol OpAmp. IC 4558 terdapat dua buah penguat jadi 2 buah gambar segitiga(penguat) wujudnya berupa sebuah IC. Dalam gambar skema, setiap penguat(segitiga) memiliki kaki 4 dan 8. Nyatanya pada gambar ic 4558 diatas hanya terdapat satu buah kaki nomor 4 dan 8. Jadi sebenarnya ada 2 buah kaki nomor 4 pada skema sebenarnya menunjuk kaki yang sama, begitu pula kaki nomor 8. - power, maksudnya diberi tegangan sesuai kebutuhan. Tertulis +12 dan -12 berarti dibutuhkan PSU simetris untuk menghidupkan rangkaian ini. - kapasitor kapasitor milar dan kapasitor elco(electrolic capacitor = kapasitor polar) memiliki simbol yang sama. hanya bedanya terdapat simbol positif (+) yaitu elco dan tidak yaitu mylar. berikut adalah panduan ukuran footprint beserta namanya bila membuat gambar jalur PCB menggunakan proteus ares download file pdf klik disini cara menggunakan gambar diatas harus mempunyai semua komponen yang akan dirakit. kemudian bandingkan komponen dengan gambar. misal: Bandingkan R1 dengan RES50, ukuran cukup pas jadi gunakan RES50 Bandingkan IC 4558 dengan DIL8, ukuran pas bandingkan potensio dengan P1, ukuran pas, dan seterusnya.
The Maestro Super Fuzz-Tone was introduced in the early 70s. It uses 6 transistors, 2 of which are used as clipping diodes. Original transistors were 2N5133s, but 2N5088s or BC109Cs can be good subs. I've built 2 clones of this pedal in the past (though not with this layout) and used 2N5088s with good results. The original Balance control was a 30k dual gang pot, which you would probably have a very hard time sourcing. In both my clones I used a 50k with no problems, but if you want you can put 82k resistors between lugs 1 and 3 to get the dual gang pot to around 31k, though it will mess with the taper some. Said Balance control acts almost like a clean blend, and the switch offers 2 different tones. If you're tired of Big Muffs, give this one a try. Works great on bass too. Here's a couple really short demos I did on guitar and bass on one of the clones I built a few years ago (pardon my butchering of a couple Black Keys songs).
When a Hackaday article proclaims that its subject is a book you should read, you might imagine that we would be talking of a seminal text known only by its authors' names. Horowitz and Hill, perhaps...

The Fuzz-Stainer is a pretty rare fuzz box made by Sam Ash in the 70s. Don't confuse this with the Sam Ash Fuzzz Boxx/AstroTone, as it's a different circuit. Original units used 2N5173 transistors with BCE pinouts. I've made 2 versions of the layout, one for BCE transistors (on the right) and one for CBE (on the left). 2N2222s or 2N3904s seem like they might be good substitutes. Output is pretty close to unity with the Volume pot maxed, so you may want to replace the 10k pot with a 50k or 100k, and/or reduce or remove the 68k resistor from Volume 2 to Out. To make the trimmer external (like the Jerms clone in the video below), use a B20k pot with lug 3 going to the emitter of Q2, and lugs 1 and 2 going to ground.
This is a pulse generator with adjustable duty cycle made with the 555 timer IC. The circuit is an astable multivibrator with a 50% pulse duty cycle. The
The Triple Wreck is a high gain distortion that some say sounds like a 5150 amp. It has a 3-band EQ and a switch to select between "Vintage" and "Modern" tones. There's also a built in boost section to take things over the top. I've laid out the distortion section and the boost section as separate layouts in case someone wants to build it without the boost in a 1590B. The boost itself might be a nice little stand alone pedal and would easily fit in a 1590A. (The boost is a simple BJT-based circuit that drives a modified Big Muff tone stack. If you wanted to add a volume control to the boost circuit, just connect lug 3 of a 100k pot to lug 2 of the Cream pot, then ground lug 1 of the new Volume pot, with lug 2 to Out.) Edit Aug. 20: Got a request for this without the ground loop as there have been reports of noise in the circuit and that could be culprit. If you've already built it, try cutting some copper near the text on the PCB.

The Zvex Super Hard On has become one of the sought after boost pedals today. Derived from the preamp section of a 60s recording console, the SHO uses negative feedback to control the gain (which is what gives it the crackle when adjusting the knob). It's capable of being a clean boost and adding some sparkle to your tone, or pushing your tube amp to break up and creating a great overdriven sound. If you want to add a master volume control to it, remove the 47k resistor and use a 50k pot. Lug 3 to the Out pad, lug 2 becomes effect out, and lug 1 goes to ground.

Here's a really cool one designed by the great Tim Escobedo. T.M.K. = Too Many Knobs. (And you thought the Fuzz Factory had too many) It's part fuzz box, part noise maker and would probably be just as much at home on a synth rack as it would be on a pedal board. This can get pretty gnarly and should fit in a 1590B.
Stumbled across this one over on the old La Revolution Deux blog. It's a simplified version of the Diamond Compressor, removing the EQ and the blinking LED circuitry. Makes for a much smaller footprint and will fit nicely in either a 1590B or 125B. Here's the schematic for reference.
