Compressor pedals are available at all price points, from Chinese-made budget boxes up to £300-plus units from Origin Effects.
The JF-10 Dyna compressor pedal is at the lower end of the scale, but is robustly built and has a picture of a scorpion on the front.
So, does it take the sting out of your dynamics? Well, it certainly has a lot of output, making it a useful clean boost, and the compression doesn't sound bad, if a little bright.
The Dyna doesn't have as much 'squash' as higher priced pedals, but you could just leave it on all the time to enhance your sound.
A workmanlike compressor for those of us on a tight budget.
