As to the tuck and roll.....a guy here did a sample of T&R for me and I couldn't tell the difference between the original and what he did. He tried cutting the V in the foam but was very time consuming and didn't look quite right. He then just folded the foam with the material and made the pleat. You couldn't tell the difference, was a perfect match in every way. He wants $150 just to do an amp head but from what I saw, it's worth every penny. He cranked out 8 pleats the exact size of the amp head in less than 10 minutes and that included marking the foam where the stitching was to go. So there are people out there who can do it.....ask for a sample first before having it done just so you can see what your paying for.
