Doubt you could do more than use the amp as it is. Inexpensive SS amps with a preamp tube usually run them at low voltages and loose much of the tube characteristic. Even if it ran a high voltage power supply for the tube it would not have the current capacity to drive more than the tube in there. It is really hard to make a tube amp for under $100 using new parts.

That produces a really nice sound. Tube amps do sound good.

That's a great sound, I am new at this - when you say effects pedal which pedal are you using exactly

Thanks

You might as well drop the 12AX7 cathode resistor in half and parallel up the other triode with the first. You would get a bit more complex sound ane a bit more gain.

Yes, but you would put the second half in series.   That would provide much more gain and overdrive.  Plenty of mods possible here.  Just take a look at any of the classic Fender tube amp designs for ideas.

Listening to the amp I do not think it needs much more gain. Mind you, that is my own personal taste.
