Reading some past threads about whether the portion of string between the bridge and tailpiece should be 2 octaves plus a fourth over the string above the bridge, etc., I checked my strings and found the following. When I play only on the portions of the strings between the bridge and tailpiece: the interval between the E and A strings is an even fourth. the interval between the A and the D is only a major third, and the interval between the D and G is also only a major third. When I play the regular part of the strings (above the bridge), they're tuned perfectly and the intervals all are perfect fourths. Is this normal? Does it matter? It doesn't seem to affect my playing, but it does seem odd.
