I use a Vox Valvetronix AD50VT - a modeller trying hard to sound valvey!
They are pretty good, plenty of variety (11 models) and effects built in, they do sound fantastic at low `bedroom hero` volumes. And the few occasions i`ve jammed loud with it have been pretty good too. I use the model that trys to imitate a Fender Twin a lot!
Forum won`t let me post a pic - i dont have 15 posts yet!!!
