@uzeurillus1on I have some experience over a period of years with the Bacchus brand.
Your gold top looks like a circa 1996/1997 BLS-95 GO (GO is gold aka gold top)
The spec should be 2 piece/center seam maple top, 2 piece/center seam mahogany body back, medium length/off-set tenon.
The BLS-95 model was a precursor to the 1998 catalog model BLS-120. BLS-120 had an upgraded 1 piece back and long neck tenon. Also serialized and typically more desirable with a corresponding typically higher selling price point.
The blue top with the black back looks like a circa 2004 BLS-59 with a custom color top and custom color back color finish. These will typically have the HB (honey burst) top color finish with a cherry color finished back and neck. I have seen one or two examples in GO aka gold aka gold top color finish with a dark back.
Your example should have a 2 piece/center seam maple top, 1 piece mahogany body back, long neck tenon and the 1021** serial number (again) indicates a circa 2004 example.
The BLS-59 was the post BLS-120 example LP Standard type from Bacchus.
I have owned several BLS-95 examples, several BLS-120 examples and several BLS-59 examples; all great guitars but as the line moved forward in time from circa 1996 to circa 2005. My favorites have always been the BLS-59 examples but they are all good guitars IMO.
Neck thicknesses became thicker as the line went forward in time that's why I prefer the BLS-59 examples.
Cheers
