In the midst of a big gear purge I came across this thing pretty cheap at a second hand shop here in Tokyo this evening and after plugging into it I had to take it home.
A 1973 Ace Tone Mini Ace. Ace Tone was founded by Ikutaro Kakehashi, who would later go on to found Roland and Boss.
It’s a funky transistor amp with a really interesting sounding spring reverb and tremolo circuit. The reverb doesn’t get cavernous but it does this really cool feedback swell when it’s cranked that almost sounds like it’s going to explode but then it washes out.
It does a nice “spaghetti western” sound, and definitely seems like the thing Jack White might dig.
The only thing is that despite being small and light, it gets loud! I can only put it on 2-3 in my place.
