instead of doing a HPF and a High Shelf boost. find a good center frequency and just use a tilt EQ point. Then turn those small dips into a single 24dB curve since they are close in frequency dip them, then after using the tilt, set it to dynamic to grab an extra dB if there's any spiky tone. Since this isn't a heavily distorted guitar part, I'd also use a compressor for shaping before EQ... but hey...whatever works to get the end result.
