I shimmed both my cheap Squiers. I noticed it was hard to get decent action without dropping the bridge saddles stupidly low and losing the break angle. I determined how much shimming I felt was needed, put in a full shim to raise the entire neck that much in relation to the bridge, and then did full setups. I got very good action and a nice break angle over the saddles on both. Both are much more adjustable and playable now.
