i picked up a laney gh50l recently. very nice, especially for the money.
However it has to be louder than my 100 watt engl before it starts sounding good, and the taper of the volume knob isn't as smooth (it's harder to get it to the perfect volume, it's a bit like an electric shower :lol: ).
It's not just about wattage, in other words. Granted more wattage generally means more headroom, but it doesn't necessarily mean it'll sound better at lower volumes.
EDIT: just to clarify, my engl has 6L6s and the laney has el34s- i've heard 6L6s make the laney sound better at lower volumes, but I haven't tried it myself.
