I’m sorry for invading yalls space, I’m hoping someone here has this information. I’m wanting to tweak my fuzz head, and there’s only one trim pot inside. Do any of you know what it does?

I’m completely baffled by the price on this.

Hola, soy Sergio y esta es la primera vez que inicio una conversación en este sitio web. Me vi en la necesidad de tener que acudir a ustedes porque la situación lo amerita.

Les cuento lo sucedido con el pedal:

Compré un pedal JHS Twin Twelve V1 que se encontraba en mal estado, me lo vendieron muy barato, y en mi país no se ve mucho este pedal en segunda mano; así que lo compré sin dudar porque el problema se veía fácil de reparar.

Lo envié a un servicio técnico especializado en equipos de audio, y al final la reparación consistió en que cambiaron el potenciómetro de volumen y también procedieron a “calibrar el pedal”.

Hasta ahí todo bien, el problema está en que vivo lejos del servicio técnico así que me lo enviaron a mi domicilio y recién en ese momento pude probar el pedal. Me di cuenta de que la perilla de volumen ahora funcionaba correctamente pero como a las 8:45 se lograba el unity gain, lo cual me pareció demasiado extraño, y con el gain al máximo el pedal no llegaba a fuzzear como en los test que vi en YouTube.

El servicio técnico me dijo que no hay un manual que les sirviera de referencia a la hora de repara el pedal, y que simplemente habían hecho la calificación que ellos sabían que era la más correcta.

Le pregunté a la IA y esta me dijo que JHS vendía el pedal mal calibrado a propósito, ya que esa era la forma en que lograban el sonido deseado.

Desde el servicio técnico me dijeron que lleve nuevamente el pedal para volver a calibrar, pero necesito ayuda respecto a información útil que ayude a dejar el pedal calibrado de la forma que lo hace JHS de fábrica.

Considero que el JHS Twin Twelve V1 es un excelente pedal, y por lo mismo vale la pena intentar dejarlo mal 100%.

Se agradece mucho su pronta ayuda.

Saludos 👋. -

Hello everyone, I've had this demonfx gravity from a trade for a while back and noticed that when the pedal is in bypass mode, There is a loud high pitch noise coming from the pedal, not a buzz or nor a hum, A high pitch riniging noise. When engaged the humming is reduced and when I use a pre amp or compressor before it the humming is now barely audible

It's more audible when used on single coil pickups, because on my humbucker guitar the ringing is minimal

Is there something I can do to fix it?

I've tried the changing the power supply but same results

Is it a grounding issue or soldering issue or a chip issue?

Hope you guys can help.

I don't know where to solder this two wiresb

Lo probé en protoboard y anda bien! Lo que si en el canal limpio de mí nativo gts 45 transistorisado no suena bien, pero en el canal drive suena joya ! Alguien me podría decir a qué se debe! Gracias!! Ahí les dejo el esqueme que hice! En la entrada es 4.7 uf y la salida es 2.2uf

Fet Reverb Surfy Bear Clone

My first post..

Though I would share my FET reverb based on the surf bear, pic 3 is the finished article sat underneath a valve amp Tube-Town.

Been trying to learn pedal repair, and my first project already has me stumped. LED only works on diode tester, no sound when pedal is on. Thought the distortion was bad due to is clipping initially when there was still sound, but seemed to be a red herring so I put it back.

Followed wiring of another RAT pedal I have, replaced a couple resistors that were slightly browned.

Thought it could be the 3pdt switch but contacts open and close as they should.

If anyone could link some wiring diagrams that could help me diagnose my issue, it’d be greatly appreciated. Pretty discouraged so far.

I just finished this build! To switch my Phase 90 from front of amp to the Fx Loop,

I plug my Phase 90 in the 'Send' and 'Return' in this photo and my amps FX send and return into the 'Send'/'Ret' Loop in this photo.

I notice when I switch my Phase 90 into the Fx Loop of my amps there is a clear volume jump since its being switch from front of amp (instrument level) to the fx loop (line level) so i would like to install a 100k pot on the 'Send' to tame the volume jump BUT only have that volume control so it is only used when the Send and Ret is engaged

Any help is much appreciated! Thank you so much

Hi people, I’m a newbie at electronics. This is my second pedal, it’s a clone of a color sound tone bender.

At the moment it does not work, the true bypass works so I know it must be the board. When I hit the switch, the LED turns on and I can hear the volume adjustment work but there is no signal. I can just hear static get louder or quieter.

This is my first circuit with transistors, the parts list and board diagrams were a little confusing for me. As you can see on the parts list, it mentions NPN 107, 108, 109 etc. so I have 3 different transistors installed. From left to right, BC107, BC108, BC109.

Have I misunderstood this, are they supposed to be the same transistors for all 3 of sockets? Would this cause the circuit to fail by having different transistors. I am also not sure if they’re installed in the right orientation. I have included the documentation that came with the board, could anyone let me know? Thank you!

Hey everyone! I'm a very basic beginner with electronics and have been working on a Tube screamer/ Rat hybrid pedal in KiCad. I wanted to get some feedback on my schematic and see if there's any issues before I start breadboarding.

Hi everyone, this is my first post. I just wanted to say how I enjoy this group. Anyways, I'm basically a fuzz guy, but have been getting into distortions again as of late. I've been building modded HM2s and would love to have this diagram with the printout for etching. I've searched all over with no luck. Does anybody have this particular circuit they could share? I'd be beyond thrilled and super appreciative. Thanks in advance for the help.

Can someone help me finish this npn dallas arbiter scheme?
