Based on the original Dumble design, this Sebago Overdrive Deluxe does a great job executing on the magic that made the original so special. Like the original, this amp is foremost a gain machine! You can set it up tastefully enough to pull off sounds similar to a cranked 100w Marshall, all within a compact format. You won't find much clean headroom in this amp, which the same can also be said about the Dumble. It has a sharp look to the color scheme between the tolex and grillcloth, and is in excellent shape, with only minor signs of previous wear. The speaker is a high-powered 90w ceramic, from our Kentucky neighbors at WGS. Sebago truly delivers admirable Dumble qualities, at a reasonably price, making this amp an excellent value piece!
