Well I sold the Laney VH-100R head and got this, plus I had a little cash left over! I absolutely love the clean channel and it sounds really great when driven by my TS808 reissue. The distortion channel however is a little different. I've sat and tweaked it for a few hours and it still sounds like there is a wet blanket over the distortion. It can sound like Rush or King Crimson, but I can't get an overly heavy distortion sound.
If you hadn't guessed it, the instrument is a kantele.
You could try swapping some tubes, but yeah, the lead channel isn't overly tight. It's VERY rock'n roll and classic metal, but doesn't do modern metal well.
