The Overdrive amplifier is inspired by the tone and features of vintage tube amps but has its own unique character. This single channel class A amp has all the clean twang you would need but with plenty of gain on tap for some serious overdrive. The combination of a well-filtered power supply and original circuitry allow these amps to remain punchy, articulate and artifact-free no matter how hard it's driven - no weird ghost notes or odd harmonics here!
The amp covers a wide range of sounds, from bold cleans to fluid singing overdriven tones, and everything in between; controls are sensitive and interactive, yet any setting is exceptionally musical. As with all Sommatone amps - this is not a replica, you won't see this circuitry, build quality or tonal flexibility in any other amp on the market.
Given that the reverb in our Roaring series gets rave reviews, we decided to incorporate it into the Overdrive's design. We've configured this exclusive circuit in a way that enables us to offer reverb as an option by wiring the reverb in parallel with the preamp (versus series which is used by most amp manufacturers). Because of this, the added circuitry doesn't color or change the tone in any way. The reverb blends with each note and becomes part of the sound as opposed to "riding" on top or at the tail end of it. The result is a lush, full sound.
So, kick your tone into Overdrive, hear the difference…
Construction, Components & Features
The Overdrive is constructed using true point-to-point wiring. By mounting all components directly to tube sockets, jacks and pots, we are able to ensure the purest signal path, maximum touch sensitivity and the least amount of tonal degradation. Our amps are handmade and extensively tested for tone, consistency and reliability.
