I’ve been wondering about tinkering with a guitar amplifier that runs of a 9V power supply for a while now. I tired a Diago Little Smasher which was loud and great for distorted tones, but not quite loud enough, or enough bass for clean. There are some cheap preassembled boards on eBay using the PAM8610 chip, they rated 10W, but this is probably only at 12V into 4ohm. I got a couple and these are the results:
– More expensive
– More bass
– Treble roll off
– Quieter (but can be as loud with a boost/preamp before it)
– Smallest enclosure probably a 1590LB
– More hum
– Less bass
– More Treble
– Louder (without preamp)
– Smaller, would fit in 1590H enclosure to make a tiny but loud amp!
Overall I think I liked the tone of the red board more, but I’ll probably put both in some projects.
