I just acquired this head from the original owner. Originally bought 5/2012. Have sales receipt for transfer of remaining 3 year warranty. Great sounding head that packs a huge wallop! Quite a hammer for its size. Nice clean, articulate, but overall warm tone. Fits nicely in my gig bag pocket. Should probably keep it (and might just do that!) but I recently swapped to a more efficient cab, opening up more options for me. Thought I'd see what's out there. Trade interests (+/- cash as necessary) would be something in the neighborhood of the following: GB Streamliner 600/900 Aguilar TH-350/500 Eden WT-550 Mesa Walkabout Possibly: Thunderfunk 550 Markbass LM II/III, TTE500, Little Rocker, R500 GB ShuttleMax 9.2 GB Shuttle 6.0/9.0 Possibly open to other models- i tend to dig warm / tubey tones. This head is minty. Can't find a mark on it. I'll get pics, but it looks like this: http://www.genzbenz.com/?fa=detail&mid=2824&sid=715&cid=95 PM if you want to discuss possible trades. Thanks!
