No pics to hand unfortunately, but the oldest I have is amps, early 90s vintage. I am not sure which is older - I have a Mark IVa, 5150 block letter and a XXX with the girls in the front grill. I assume they are all probably 92-ish but the Mark IVa might be 1990, and...
I spose it’s not a production guitar but that BC Rich single cut that Meegs was rocking in Coal Chamber is my ultimate white whale. The pics are on the site here somewhere. Other than that, I reckon those Grohl Trini Lopez models are amazing.
