Hi, I have a thunderfunk tfb420 amp I am putting up for sale. It is in great condition and sounds great. Just in case you are wondering if these things really sound that good, the answer is yes they do. Everytime I think of going with something else, my t-funk always sounds better and is lighter and more tweakable. Unit has been lightly used with no problems whatsoever. Some people have responded with a proper price for the TF. 700+shipping brings it to your door.(Sorry, since these things don't come up that much, I had no idea how much it was worth, not trying to be a jerk) please e-mail me at email@example.com for questions (I Do have pics) P.S. I am selling because the job I'm doing now only requires me to go direct and I need the money.
