For the last couple years, I've been gigging with a Fender Rumble 500 combo, which sounds great and is mercifully lightweight, but I played through an Aguilar Tone Hammer 500 and DB 212 cabinet recently and loved the fullness of the sound. Since then, I've been thinking about upgrading to an Aguilar TH 350 with a single SL 112 cabinet, and I'm wondering how it might compare to the Rumble 500 in terms of volume / headroom.
I'm not an electronics wiz, but my understanding is that if you use the Rumble 500 without an external cab, you're actually only getting about 350 watts of power because the impedance of the combo is 8 ohms. The full 500 watts is available if you hook up an external cab and impedance drops to 4 ohms. As for the Aguilar SL 112 cab, that has 8 ohms impedance and power handling of 250 watts, so I guess 250 watts would be its limit when paired with the TH 350 head.
While I realize that amps of the same wattage can differ significantly in volume, I'm imagining the that the Rumble 500 without an external cab would at least be in the same ballpark as the Aguilar TH 350 + SL 112 (350 watts vs. 250 watts). Does that make sense, or am I underestimating the drop-off in headroom?
The reason I ask is that although I've almost never turned the volume knob past noon on the Rumble 500 (I play alt-country and folk-rock, generally in bars and smaller venues), I want to make sure I wouldn't be losing too much headroom if I were to switch to the 350-watt Aguilar head and 112 cab.
