The Magpie Octal 21 is a clone of the Combs JJ-150. The circuit is an attempt to to emulate a Gibson EH-150 amp with octal tubes. It goes from Charlie Christian to Junior Barnard.

When Guyatone first began plans for the mighty micro series, they polled professional musicians in Japan to see what they felt would be the most useful pedal for a working guitarist. The answer was what would become the SSm5 Sonic Shaper!

Based on the original Guyatone EX-2 Exciter model (never sold in the USA), the SSm5 is a harmonic booster pedal that, by emphasizing specific frequencies, can offer the guitarist a broad tonal palette. The key to the SSm5 is the Shape control, which adjusts...

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.

Here the voltages, all measured against circuit ground (not DC adaptor ground), pedal on, switches off, knobs at 12 o'clock

Q1 J175 Pedal ON

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.
