I’m impressed that you recognise the owner and the shop from one photo of the bass
Yeah, Mark was a great guy - I bought quite a few guitars, basses, setups, strings etc, from him over the years.
Boring story alert...
First visit was just before Christmas 1992 (I was 10 years old) for a replacement string for my terrible catalogue guitar. So obviously when my birthday came round a few months later, I wanted a new guitar and I begged my Dad to take me to Mark’s shop so I could try some out and choose one.
I fell in love with a Yamaha Pacifica which was £25 over budget, but Mark overheard my Dad trying to steer me towards something cheaper and reduced the price on the Yammy. And threw in a gig bag as well. That was the kind of guy he was
And his setups were second to none, extremely thorough and quality service. Great guy, great musician, great shop.
