The Orange Thunderverb 50 is a bit of a unique design.

To start, it's a 2 channel amp that utilizes a special designed transformer that allows the  amp to recreate bass frequencies all the way down to 30hz without loosing definition, and that is *REALLY* hard to do!  Leave it up to the genius of Ade Emsley at Orange UK.  I've had dinner with him on more than one occasion, and take it from me, the guy knows his stuff as well as anyone in the biz!  His design allows the lower frequencies to really cut through when playing with drop tunings or baritone guitars.  Naturally, it sounds stellar with regular tunings on normal guitars too!

The Thunderverb 50 also comes with a built in attenuator allowing you to crank the amp (which is absolutely what tube amps need to sound their best) and then attenuate the output wattage to the speakers so the overall volume can be tames.  AWESOME for multiple reasons...  One, in keeping the neighbors and their phones calls to the local authoirities at bay!  And secondly, you get to keep your tone at gigs where the sound guy (or those never understanding band mates) are always crying like a baby to turn down!  As you may kniow, then you turn a tube amp down, you lose tone.  LOTS OF IT.  An attenuator helps solve this problem.  For more info on attenuators, you may want to check out an article we wrote: WHAT IS AN AMP ATTENUATOR?

So, what else is special about the Thunderverb 50?  Well, how about a fully tube driven 3-spring reverb that's super lush?  Yep!  It's got it.  It's also features one of the finest Effects Loops out there.  Orange pioneered tyhe amp effects loop back in the 70's, so that should come as no surprise.  :)
