You will notice in the photos belos the 30 degree angle pointers on the control knob. This is usually a pretty good indicator of an early-80's RLG Burny. These RLG-50s had the lower-end pickups and wiring and poly finish but were very well made guitars, if not a bit heavy on average. Three of the four I had were around or over 10 lbs!
These models can be deceptive due to their looks and lack of a model number on the guitars. I have seen more than a few owners of likely RLG-50s assuming that the nice top on their guitar means they must be RLG-120/150/custom orders. That is a pretty good compliment to for the lowly RLG-50!
