Chorus is an effect I've "Done without" for over 10 years! I can remember the early versions, and now there are quite a lot of variations available. I wanted a basic simple to use, but good traditional sounding implementation. I also have quite a few other TC Electronic effects - They're all impressive and of excellent standard! The manufacturer gave me the confidence in a much lower priced product. I'm not disappointed. Just 3 controls, and I started with everything at "12 o'clock", which worked excellent! That's a good test of any effect or amp. I don't use chorus that often, but now I have an excellent sounding addition to my pedalboard. The 4 little feet had to be removed and velcro fitted to mount it on the pedalboard. I noted another reviewer's comments about stiff Philips screws, so selected the proper No.2 Philips screwdriver - only to find there was no battery inside anyway. I got caught out some years ago by failing to remove the battery from a pedal and it corroded the case from inside. Just making sure this time.
