The Grammatico GSG is world-renowned, having even been immortalized digitally within the Line 6 platform. In addition to being a thoughtful interpretation of a Dumble circuit, this special edition includes the following upgrades:
-
1965 Fender Twin transformer set
-
Mallory Made-in-USA filter caps
-
Assorted NOS and audiophile-grade resistors
-
NOS GE power tubes
Whether it sounds exactly like the original is often debated, but judged on its own merits, this amp delivers a wonderfully nuanced overdrive that will impress even the most skeptical players. Like the real Dumbles, the midrange switch provides a genuine midrange “quack” that helps the tone punch straight through the mix. Overall, this is a wonderfully crafted amp that pays great homage to the legendary Alexander Dumble.
The amp has light signs of previous wear, with some subtle staining on the top side.
