This head is a beast! All info about specifications you have on orange amps site.
But the best info of the sound of thunderverb 50, recorded with mics from 100$-2000$, you need to go on YOUTUBE and type (or copy/paste):
Recording 2 Electric Guitars With 8 Microphones ( mic / guitar test )
Sound in this video is very good quality! So The sound will speak to you by it self and you will hear best review of this amp ever by using channel B! You will hear just DRIVE SOUND! rock riff and riff using just one string (korn style) and modern rock open riff.
Read description about all process and all used gear.
I did this for all Orange fans, and gear slutz who want to hear difference in sound , using different mics and combinations.
Cheers and have a nice listening!
