I'm selling my beloved Thunderfunk TFB420. This had some upgrades by Dave Funk previous to me getting the head. It worked great before it quit working, so selling as a project. It still powers up, but no output. It hasn't been turned on for more than a second since it quit to keep from causing more damage. Since I have my Eden WT400 and an A.M.P. Series 220 and there are no repair facilities I trust near me, I'm letting this go as-is. Asking $260 shipped to the CONUS. It comes as pictured with no cord included. I opened it up and took a pic of the inside and the 4 burned resistors on the power amp board. I managed to find the schematics for it and can print them or send a PDF of them to whoever buys it. PM me for any questions or to make a deal. I am open to a trade or partial trade. I'd consider a smaller head like a Genz Benz Neopak or Markbass 250, or another small bass head. An Avatar neo single 12 8 ohm cabinet. I'd take a set of Bartolini, Nordstroms or Aguilar 6 string soapbar pickups, a Bart or Aguilar 3 band pre or an Ibanez or equivalent 6 string body as a partial trade, or ??? Let me know what you've got. Thanks for looking.
