I was buying a new PT for my 5F11-ish thing and decided to get an 8K ot for my 5E3. I bought the 1750E based on the info on the Hammond website. However, I overlooked the dimensions. The 1750E has 2 7/8 inch spaced mounting holes whike the OT I have - as well as the Mojotone Tweed Deluxe OT - have 3 1/8 inch hole spacing. The DR OT looks much bigger than the Hammond, and the pictures on Robrob's 5E3 site look as thought the OT is bigger. What are tge correct dimensions for a 5E3 OT? Has anyone used the 1750E for a 5E3?
