Custom Line Thunder 99 : Great idea...but

I got excited about this product early on in 2019, and ordered it for arrival in July. Product arrived ok, and worked a charm with Mooer compact preamps meaning I had a HUGE amount of tonal and volume choices from a very compact pedal board. The Thunder was loud enough in to 2 x 12 to keep up with drummers in bands (match that impedance, though!!) and was "clean" and uncolouring. Even the size of the volume meant I could gently ride my level when the band got excited. BUT....

After 1 month of use I found I was getting electric shocks from the unit. I isolated it from the rest of my gear and so ONLY the pedal and PSU were in use, and sure enough 5-8V were measured. I could "solve this" by plugging in to an earthed product but that isn't right. Unit is being returned and I'll update you when I have news...
