    Quality:

    This is one very easy to set up amp. I used a 20k pot because that is what I had. it works fine. I put it to use driving an old 6x9 car speaker in a speaker box for that size speaker. I used a 470microfarad cap to block DC to the speaker but 1000mf would work fine I tried it. I ran the output from a mixer to that amp and it did fine with a mic, Then I tried an electric guitar to it. It works fine but does over drive easy. Then for the awsome discovery. I plugged the guitar straight into the 20k input pot and then cut the voltage from 12 volt to six volt with a current limiting resistor feeding a 1000mf cap and I got the most incredible blues and or rock distortion out of that car speaker which I put a mic in front of in the studio to record.. I actually sat there and played guitar for a couple hours listening to that car speaker and its distortion when it is starved for power. Very cool I ordered in two so I can make one for my brother.. Thanks for the fun. I am tempted to order in the 12 watt one to see if it will work for a small guitar amp to play on the tailgate of my blazer at the cabin running on the car battery. If I get one I will let you know.
