A true gem from Gibson’s golden era of tube amplification, this 1965 GA-5 Skylark delivers all the warmth and character you'd expect from a classic low-watt combo. Rated at approximately 5 watts, it’s a perfect amp for recording, home playing, or vintage tone enthusiasts.
This particular unit is in good vintage condition, showing some light cosmetic wear consistent with its age but remaining fully functional and sounding great. The original 8" speaker (typically Jensen or CTS) is intact and performs well, offering smooth breakup at moderate volumes. The amp retains its original tolex and grille cloth, both of which show minor scuffing and discoloration but no major tears or structural issues.
Powered by a simple and reliable three-tube complement — 1x 12AX7, 1x 6V6GT, and 1x 5Y3GT — the GA-5 Skylark is prized for its rich, creamy overdrive and touch-sensitive dynamics. With just a single volume control and two inputs, it’s the epitome of plug-and-play simplicity. Plug has been upgraded to a 3 prong for safety!
