Basic Operation

With a semi-hollow and humbuckers, you can feel the connection 

between guitar and tubes. You can push it just hard enough to 

break up, while most of your notes are clean and clear.

Memphis Boogie

Dirty blues will hit your amp hard, if you’ve got the chops. This will 

dirty up your Strat

®

, but you’d better hit hard and dig in if you want it 

to get greasy.
