I'd say ET65 ... but it sounds like you would probably consider it too dark.  So...

Go G12 for a totally vintage Jensen/CTS American sound

Go Reaper HP for a slightly Britt voiced tone

Hope this helps ... post back here w/results!

In the Brit-sound area, why do you prefer the ET65 over the Reaper for this amp? Can you explain your reasons?

thanks

Personally, I find the HRDs to be a bit strident and overly crisp on top ... so I like the way the ET65 smooths out the top end.

Strident and overly crisp on top...i think the problem it's not the amp but the characteristics of the stock speaker.

See this modded HRDx with Reaper speaker. What's your opinion?

Thanks, Lorenzo

I agree ... I've always said that the first place a manufacturer will look to when trying to cut the cost of an amp is the speaker!  They will choose the cheapest thing they can find ... of Chinese origin ... then give it a cool name and put a nice sticker on it ... like "lipstick on a pig" ... or as I look at it "polishing a turd"!

The HRD is no exception ... But since your original post stated: "i have a Weber Chicago 12" speaker but it results too dark" ... I would say that you would find the ET65 too dark also!

Thanks, Vaughn

And what about the new WGS  Liberator 80 for this amp?

Haven't tried it personally ... but it hit's me as a good match.  The Liberator is a fairly warm speaker, but not so much as the ET65.
