We have and continue to offer Maple in LP necks from time to time. In our regular production, Custom Shop Zakk Wylde models for example. Zakk's are paired with active electronics so difficult to compare with passive electronics and Mahogany when plugged in. But unplugged........
Many players and luthiers that I know (myself included) prefer to try an electric guitar unplugged in a quiet surrounding. You can often hear and feel the tonal differences between various guitars, even within the same model. Once in a while one just jumps out at you.
Play the open A string, gently feel the headstock. Mahogany neck will resonate quite a bit, Maple not as much. BUT NOT ALL OF THE TIME since every piece of wood is different. As mentioned, the Maple probably adds sustain and edge, Mahogany resonance and thickness. Nuances are what make us all different, and our guitars.
That's why a universal truth exists. "How many guitars are enough?.............just one more Darlin', just one more......."
