Black digital guitar tuner with blue LED screen

I lost my black digital guitar tuner yesterday around 3pm near the Winchester Guildhall on High Street. It's a compact rectangular device, about the size of a matchbox, with a blue LED screen and a slightly cracked top-left corner. It lives in a snug black silicone case, and on the back there's a small white sticker with my initials 'PP'. It's essential for tuning during rehearsals and gigs, so I really need it back. If anyone finds it, drop it at the Guildhall reception or email me at [email protected].
