Got a 66 SF3 and 62 T100D I know they are both true hollowbody guitars. Were all guilds made that way or were some constructed with center block like a 335? Did the CE100 have a block? Would love to own a CE100 with Franz pickups
The ones that looks like a 335 are constructed like one (i.e. Starfire IV, V, VI and XII). I believe some of the single cutaway models here and there may have things like soundposts, etc., but I don't believe any of them have a full length neck-to-tail block like a 335, except the double-cut Starfires.
What Kakerlak said - I don't know of any single cutaways with a center block. Some later guitars like the X170 (and some X500's) have a fairly big soundpost under the bridge, but still no center block.
