"One Puff" All Tube Cigar Box Amp Demo Clip

Ok folks, here is a sound clip of my "One Puff" one watt all tube cigar box combo amp. See pics in the picture section. Recorded with a large condensor mic with NO processing. The clip starts with some clean sounds then to overdriven tones both straight into amp. Last part of clip is through an effects pedal. The amp is super quiet and the little 4 inch speaker does quite well for what it is. Would make a fine little recording amp. I took it to our local blues jam last night and blew harp through it, miked up of course, and it sounded fantastic. Enjoy !

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.
