Here we have a custom-built Ol Yeller lunchbox head, the brown bassman 6G6-B normal channel.   Includes what I believe is an upgraded 50 watt Hammond transformer and a switch on the back for 8, 4, or 2 ohm load options.  I believe the front controls are for Presence, Bass, Mids, Treble, and Volume.  External bias taps for easy rebiasing of power tubes.  It is quite loud.  Tubes will be individually wrapped and stowed inside the amp prior to shipment.  Sold as-is, no returns.
