The Friedman Mini Dirty Shirley guitar amp head is a compact and powerful amplifier that packs a punch in its small package. Designed and built by renowned amp builder Dave Friedman, the Mini Dirty Shirley is an affordable yet high-quality amp head that exudes classic British rock tones.

One of the main features of the Mini Dirty Shirley is its simplicity – it has only two channels, each with its own volume and tone controls. This streamlined design allows for easy tweaking of the amp’s sound and encourages the player to focus on their technique and playing style rather than a multitude of knobs and switches.

The first of the two channels on the Mini Dirty Shirley is the clean channel, which offers a warm and smooth clean tone that is perfect for jazz and blues playing. The second channel is where the magic happens, as it provides a crunchy and aggressive distortion that is ideal for classic rock and hard rock styles.

The Mini Dirty Shirley’s distortion is powered by two EL84 power tubes and three 12AX7 preamp tubes, which combine to deliver a dynamic and responsive tone that is both powerful and articulate. Additionally, the amp has a switchable high and low gain mode, which allows for greater flexibility in shaping the distortion sound.

In terms of build quality, the Mini Dirty Shirley is a solid and reliable amp that is built to last. It features a durable and lightweight chassis that is easy to transport, and it is equipped with a high-quality Celestion G12M 12-inch speaker that is capable of handling the amp’s powerful tones. Additionally, the amp features a range of connectivity options, including a series effects loop, speaker outs, and a footswitch input for remote channel switching.

Overall, the Friedman Mini Dirty Shirley is a versatile and powerful guitar amp head that offers great value for money.
