On multiple guitars
I don't so much have redundancy as a theme in my choice of guitars.
The two outliers are a Kritz strat-alike and a Tacoma acoustic.
The other three guitars are all Gibsons. A 1980 ES-335S (solid-body 335 shape), a 2000 ES-346 and a 1998 LP DC. All double cutaway, short scale, dual humbucker. Different pickups on each one, and different construction as well.
I'm waiting for my fourth "theme" guitar. This one's being built by Saul Koll. Size and shape similar to the 346, with some minor tweaks to suit my preferences. The body is hand-carved maple, with a pair of mahogany rails where there'd normally be a center block. The neck is mahogany.
