I was playing guitar in 1978 - bought a brand new Gibson Firebird reissue with case for £395 from a shop in Sheffield called Sudbury Music.
Had it a month but could n't get on with it so took it back and swapped it for a tobacco sunburst Gibson Les Paul,complete with Gibson Protector
case! Think that was around £450 - seem to remember that discount Gibsons were unheard of through authorised dealers, so a lot of shops used
to obtain them from Europe (Holland mainly?) and bootleg them into the UK.-mine was one of those I believe! Great guitar though.
Other shops I have fond memories of around that time were Carlsbro (Mansfield), Music Ground (Stainforth), Scheerers (Leeds),Tim Gentle
(Southend),Musical Exchange (Brum). Back of Melody Maker was the place to look for s/h stuff, along with all the London stores advertising
Fender,Musicman and Gibson gear etc. such as Tempo, Orange, Macaris, Rose Morris, Argents and all the shops down Denmark St.
My band (that was wowing the working mens clubs around Yorkshire) decided to invest in a new PA system. I remember Rick Harrison at
Music Ground in Stainforth (near Doncaster) opening the shop specially one Thursday evening to demo an HH PA set up for us - MA150 mixer amp,
pair of Pro 200 2x12 cabs, a matching slave amp and a pair of 1x12 monitors! Think that came to around the £400 mark, and we used that PA
wherever we played, all 150 watts of it! Never let us down either. You can probably get a similar small PA now for around the same money-crazy!
