the guitars used were gibsons

the amps were vox tube amps not cabinets but the recording style called for a seperated amp from the recording studio

they put the amp in a room alone with a mic to record it without the noises from the open studio

tellis makes a similar amp now that is lighter but not cheap

ive played bass since i was 11 and worked in a recording studio for a while

but all i had to do was a simple search on the studio sites
