This great little combo tube amp was built by (who?) and sold through Sears and Roebuck in the late 1960’s and early 70’s. It was originally sold as the Silvertone Model #1421, and in later years as the SR 10XL, and lastly as the Sears 10XL. Oh, the photo of this amp looks innocent enough, but, this is one serious sounding tube screamer. And you won’t usually find them as nice as this one!

Vintage sound without the high price. The Sears 5XL is a 5-watt, old school, hand-wired, all tube guitar amp. Lots of midrange growl and smooth overdrive.
