The Stella Amp!


Have questions about the Stella amp? Having problems assembling the kit? Or maybe you want to post links to pics of your Stella amp build? This is the place for it!

Is an "effects loop" possible?

Hello -

I recently ordered the kit and can't wait 'till it gets delivered to start putting it together. I'm very excited about this project. I too have build some basic small amps based on the LM386 and I agree, they all sound -more or less- the same.

I read through all posts in the forum and could n't find a similar thread so I hope it's OK to start a new one.

Spring reverb anyone?

Hi! I'm about to order and built a Stella Amp.
There's a question I would like to ask first.

Has anybody modified or extended the Stella Amp with a spring reverb like this?

I was wondering how I might be able to integrate this schematic into the Stella design.
This design uses the 386 amp. I don't want to make the sound worse with such amp on the input....


Thank you Thank you Thank you!

I am so appreciative of your circuit. Thanks for designing something that truly sounds good while being easy to build. The ubiquitous '386 designs, while simple, sound terrible and I don't understand why others aren't more interested in finding newer more flexible, inexpensive, better sounding, and easy to build designs like yours. I built one Stella and after playing through it for a week, I ordered another so I'll have it handy when I find that "perfect enclosure". Am finding myself playing more through the Stella now than my primary amp.

High Gain

Hi There, I wanted to first mention that this is a fantastic little kit. I finally built mine and noticed that I can barely get any audible sound unless I crank the gain. Granted It sounds nice and gnarly, but There does seem to be a lot of acclaim on the interwebs for the clean tones. So, I'm wondering if I could have done something obviously wrong. Didnt notice any bad solder jobs but I havent looked super closely yet. As for power, Im using the 4pack AA batteries and tested it on a 8ohm cab (100 watt max) and a 4 ohm guitar speaker. Thanks,

Your Files on circuit board

Hi John, is it ok to print and use you drawings of the circuit board on you site to make a copy of the circuit board at home? If so what layers would I print to be able to etch top of circuit board and what layers do I need to print to etch the bottom part of board. I will not do this of course if you did not intend for anyone to make a copy of you circuit board.


sounds like a great solution (pun intended)

john, i'm so excited about finding this amp! i make cigar box guitars and amps and sell them all over the world - - i have used noisy cricket, ruby and gems, but they are all made for "real" guitar speakers - hopefully this is the answer for small speakers

sorry about your flooding - that happened to me years ago and flooded my whole house

i'm ordering a couple of boards and am gathering up the parts online as i live in the middle of nowhere
