Hi,
Could someone please let me know how, by looking at a picture, can you tell the difference between a Thunderbird IV vintage starburst and a Thunderbird Classic IV Pro vintage starburst. As far as I can see they both have 3 control knobs.
Has the location of the plug for the lead moved from the top to the edge on newer Classic Pro IVs?
Is the location of the strap lock a distinguishing feature.
I've attached photos if that helps.
Thanks in advance for your help.
