Description

The SA28 is an original Schreyer Audio design. A surprisingly loud 28 watts from a dual 6L6 fixed bias output stage driven by a split load phase inverter. Two input jacks (#1 High full input) , #2 Low (-6dB) or patch out full. A bright/normal switch, Volume, and a Treble, Bass, Middle tone stack. We use a classic plate load blackface tone stack. In addition, we offer a unique and very versatile low mid shape switch. This switch offers control of the low mids in order to dial in your tone depending on the particular guitar and cabinet/speaker combination you are using. Whether it’s a single coil or humbuckers, 12’s or 10’s, closed back or open, the low mid shape is an amazingly useful tone feature. It loves pedals, so put your pedal board in front for all the effects you want and you are good to go. The amp is housed in a smaller 20″ wide cab so it is manageable size and weight, but plenty loud. An impedance switch is included on the back (2, 4, 8 ohm positions), and two speaker jacks wired in parallel. Outside bias probe points are included and an external trim pot so power tube bias can be done with a simple volt meter and without removing the chassis. The combo comes with an Eminence Cannabis Rex Hemp cone speaker (8 ohm). This speaker complements the amp well with a strong bold tone, bell like highs, yet a nice organic feel from the hemp cone.

Each amplifier is hand wired in our shop in Raleigh, NC, USA.
