1970 Ampeg AC-12


This 20 watt amp was only made for one year, which isn't surprising since it was meant for accordion. It sounds great for guitar, much better than I expected. The accordion input is quite sensitive so it is easy to get the amp to distort. The tremolo and reverb are also really useful.
