Lotsa bass players have heard about SUNN. And those bassplayers who had the opportunity to play a well maintained Sunn rig loved it. Sunn is now gone. Conrad amps is home of former Sunn owner Conrad Sundholm. He now creates guitar combo's. And the C4 bass preamp. http://www.conradamps.com/www.conradamps.com/Welcome.html I'm interested in this bass preamp. Who owns one and how it's like?
