Just testign the waters to see if there might be something of interest in terms of trades. I really like this head, which is why I'm only really interested in a few possibilities at this time. This is MusicMan Audiophile HD-500 head, which was made around 2001 and features 500 watts at 8ohms and two channels. The preamp is driven by a single 12AU7 (as opposed to the noisier 12AX7) tube and it includes a +10db pad instead of the standard negative pad that is commonly used for active inputs. This head also includes the Loudspeaker Variable Response (LVR) feature, which allows you to essentially dial in a number of tones by simulating different cab/speaker dimensions. This makes the head quite versatile in terms of allowing you to dial in some vintage tones when needed as well as some more modern tones. The head includes a footswitch, which allows you to turn off the boost and EQ and utilize the mute function. EQ-wise, it features Bass, low mid, high mid and treble adjustments. It also features a simple limiter/compressor that allows adjustment for two settings: high and low. This head was built in Italy and there are a few threads on the board which feature info, reviews, etc., if you care to search. Basically, it's a great all-around, versatile head that offers plenty of power, even when run through a single, 8-ohm 4x10, such as I have done live. It is in very good shape and, like I said, I'm just testing the waters a bit to see what might be offered. At this time, I'm really only interested in a different head, potentially, and I'm specifically interested in a G-K head, but I would entertain other potential head offers. Feel free to PM me if interested.
