Must be an Ibanez day...
I was rummaging around in my shed looking through old boxes of junk (and tossing half of it) and came across my OLD Ibanez Overdrive. It is vintage enough to not have a 9V plug so only runs on batteries. Internally it is a Maxon device from probably the early '70's.
In the same box I also found a ETI424 spring reverb device which should keep me out of mischief for a while...
