Actually, I did have a problem with DC leakage/amp shutdown with a 0.5/3i combo. BAT diagnosed it as a bad resistor, fixed it in 24 hrs and I had it back in about 4 days total. Never had the problem again. And a hearty re-inforcement with the gain matching comments. I sold a CAT SL-1 MK2 that succeeded the BAT I had cause the stepped gain attenuator could not be properly "fine tuned".
