A-10 – A-60 – A Series of 10W to 60W Guitar Tube Amplifiers

Order this product

The A10-A60 series are push-pull tube amplifiers featuring different output power with a possibility to individually adjust the design. The size is rather compact for devices of such power. The amps can sound both soft and aggressive, depending on the settings used.

The sweep knob allows to control the balance between high and low mids giving the ability to dial in a wide variety of tones ranging from a bright and glassy, to thick and deep.

These tube amplifiers are useful in situations when a classic transparent guitar tone and predictable results of using guitar effects is required.

The circuit is made using point-to-point wiring method and amplifier’s case is hand-made. You can specify any customisation in your order. We accept custom orders on both the exterior and circuit design.
