Watch the Tone and Gear online guitar lesson by Jason Loughlin from Focus On: Western Swing
The guitar of choice was an archtop. Mostly gibsons though you did see some strombergs and D'Angelicos. You're going to want heavy gauge strings so you can really dig in. Don't worry you won't really be doing any bending more than a quarter step. What do we know about the amps? This gets a little tougher to pin down. Not a whole lot of documentation about who used what amps on what. Luckily, there weren't that many good amps to chose from. So chances are these western swing giants were using Gibson, epiphone and Rickenbacker amps. Low wattage, single speaker amps with volume and tone knobs. No effects were used.
