Well I never get to crank to 10, the most I think I'll ever need to go on the master with the laney is 4-5 which is still bloody loud.
On the TDPRI forum, I posted asking about the G12H vs the Wizard and someone who has used both says:
"Well, this is all subjective and opinion....BUT, I'd get the Wizard any and every day over the G12H. And I've loved the G12H's for many years, but Eminence has improved on the concept in my opinion.
The Wizard is a very versatile speaker and perfect for the AC/DC crunch you're looking for. Nice lows like the Celestions, but better articulation and overall tone. Very thick. Very loud. I heard/played through one in an 18watt Marshall combo clone and the tone was amazing. I'll say again...loud. Sounded like 2 12's and not boxy at all like a 1X12 can sound.
Yes, I would definitely say the highs are rolled off....especially compared to an "American" styled speaker or even the British Celestion Blue model. Great mids...really substantial lows, but not muddy. Sounds big. When I was trying to decide on a speaker for my cab, EarCandy described the Red Fang as Cream/early Brit tone and the Wizard as AC/DC type. Since I already had the Legend GB128 they suggested the Red Fang for some balance and upper end chime....said the Wizard would be very similar to the Legend."
Sounds good to me. Now the main thing that I'm concerned about is the volume, loads of reviews say it is very loud, which would mean even more attenuation :( Theres a link someone else posted comparing the two but I'm still awaiting activation to access the forum -
