Old Studio Stage 500 ShoBud amp value

[Jonathan Wehman]

Can't find anything comparable on the web so I'm wondering what a Working "Studio Stage 500" Sho Bud amp is worth.

I worked for the company that built them and have a flagship amp in great shape, original JBL"D" 15" speaker. Still sounds great.
Plus the Maverick guitar built for Bonitron to prove out the Studio Stage 500 amp design. This guitar was never sold, SN 10000
Along with that I have the original volume pedal, original curly cord, original bar.

I know the amp must be rare as I can't find much on it. Also have 2 other proto versions of this amp head from early design changes.

Is this (never sold) guitar and (mint condition) amp combo something special that's worth more as a set?
or
Do I sell them individually as just any other guitar and 100w amp?
