Hello, everyone!
I was lurking the forums for quite a long time. During this time, I nicked plenty of circuits and ideas for my personal collection. Now, the time has come for me to repay in some way... even if it is a small one :)
Three years ago, before I have started dabbling in the FX scene myself, I have acquired a Hiwatt Tube Overdriver pedal. It was being sold brand new at a half price (they must have not been popular here in Poland), so I picked it up, while my friend bought a Hiwatt...

Good morning everyone, I would like to ask for help regarding the chain of effects that I would like to use for my setup.
For obvious reasons, I need to have the Treble Booster on a dedicated line and the rest of the effects on the other.
To do this I built the Passive A B Y box and the micro mixer by General Guitar Gadget.
All good, except for the fact that the sound becomes incredibly trebly.
Initially I had thought of adding a dual buffer to the A B Y box but it would have created problems...

Helloooooo,

I checked the connections twice and also double-checked the values. The numbering doesn't follow the PCB at all because the PCB numbering is buried under the components.

Hi friends!
Is there any information on ProAnalog Fuzzes? I think they were top as for representing traditional rock / blues rock sound.
I found the layout on one of the forums and assembled it on
a pref board using old military soviet germanium transistors. It really sounds excellent.

Hi there. I am from Ukraine and I want to present you my project of low-voltage tube overdrive on a 6И1П (soviet analogue og ECH81).
Scheme:

Sound is recocrding on a blackberry q10 (tube overdrive - tube SE - 1x12 Seventy80):

Hi i'm needing some help with this.
I bought an MZ-2 on reverb with the mode knob not working properly.
The MZ-2 is an analog pcb which is the drive circuit sandwiched to a digital pcb which is the chorus/doubler circuit.
The issue being the Mode knob stays in drive mode no matter where i set it. I poked every solder joint with a chopstick and could barely get a whisper of the chorus/doubler signal. I even flowed some solder to the obvious connections to the mode knob and checked the...
