What is your opinion of this product?
This is my third CUB 12R in 2 months, first one from AMS. First one had a Polyswitch issue, second died in 60 seconds after unpacking. This arrived on time from AMS and has been functioning perfectly so far. This little amp, though fabricated in CHINA, has that english tone and warms up nicely with single coils. That Blackmore grit sound. I swapped the tubes for Mullard and the speaker for a weber blue dog. What difference in performance! Great pice point to start and modestly mod. For my ears, better than a blues jr could ever be after mods. The 1 watt step down, makes driving at low volume a great recording option. I could not give 5 stars with the modifications done on my end.
