Two-channel tube pedal amp for electric guitar

Always dreamed of "making friends" with electronic lamps. It seems like nothing complicated in circuitry, but ... in fact, a dark forest, if not space)))
After acquiring the guitar, the question became acute: "How to record the scores of your own songs?" There were no problems with transistor guitar “gadgets”. The Internet is full of schemes, even branded ones. And with the components on the market, everything is simple. Cloned several pedals from different manufacturers. Tested in different combinations. I found a “tasty” sound for the guitar and, ... .. assembled a hybrid of different circuits in one bottle (case). I use it with pleasure, only the sound is not studio of course. The lamp has always been on the throne in guitar music, although it is not alone in the chain of mesmerizing rock sound.
Two-channel tube pedal amp for electric guitar

I studied the circuit on the Internet. And started manufacturing. According to the block diagram, I have: the 1st “clean” channel through the 1st passive 5-band EQ. The 2nd channel is “overloaded” through the 2nd passive 5-band EQ. The low and high frequency controls are not displayed on the front panel as needed (they are tuned during commissioning to limit the bands). But the lower middle, middle, upper middle for active use.

Switching between channels is carried out by an electronic switch (k561tv1 and field-effect transistors). Switching control - LED on the front panel. You can switch using the button on the front panel or the pedal connected via a 6mm Jack to the socket on the rear panel of the case. The effect level control on the rear panel (to balance the balance between clean and overloaded). Ancient domestic lamps 6N2P. “Fusyats” seem to be, but the people on the forums say that imported 12AX7 howl more musically. Therefore, tube equipment Peavey, Marshall costs money. But the inhabitants of our site build your own happiness ... not expensive and tasteful)))

As the saying goes: "From what it was!" It turned out a toy for beginner guitarists, you can indulge, but .... I admit, it is very far from ideal.Although, as it turned out, when using cabinet simulators in the add-on (who knows what I mean), you can achieve a decent sound.

Don’t worry about 12AX7 and their hypothetical musicality - 6N2P is a very good lamp and, to say it, your sound passes through at least the electronic switch and equalizers. Here we are not talking about high fidelity gain.
Yes, that’s even better.

Tube panels were equipped with aluminum cups with springs, which were installed after installation and commissioning.
Perhaps it is worth making a spring clip of lamps (as was done in TVs, for example).
