I have a 1967 GIBSON TITAN AMP (head and cabinet)

It originally was outfitted with two 15" JBLs. I believe they would have been two D130s. It's an awesome vintage piece but when we received it didn't come with JBLs as advertised. There are currently two crappy Olson speakers in it now. So we want to either try to return it to it's original form with appropriate JBLs (D130s?) or advice on which JBL models would be best. We use it for guitar, vocals and even play some lps through a MARANTZ receiver and DUAL turntable.

I greatly appreciate your advice and help!

It's a 48 year old amp is in good condition and sounds great. The amp comes with a foot switch, casters on the cabinet and a tilt bar which swings out of the back of the cabinet so it can be angled backwards. Two isolated channels on the head. One channel features Tremolo. Players can patch the two channels together from the parallel inputs found on each channel. This way you can drive it into overdrive using channel one as pre-gain channel.

Speakers: 2 x15" JBL
Inputs: 2 on each channel
Channels: 2
Volume Controls: 2
Tone Controls on each Channel: Bass, midrange, treble
Tremolo: Depth, frequency
Reverb: No
