Description

The Schreyer Audio ‘SA35’ is an original design inspired by our favorite mid powered blackface era amplifiers from the 60’s. These amps were powered in the 40watt range from a pair of fixed bias 6L6s. We think this is a great power level for modern day that gives you enough volume and headroom for rehearsal and stage, but also can achieve a nice pushed tube amp feel at higher volumes. Examples of amps in this category would be the Pro, Bandmaster, Super Reverb and Vibrolux. We opted to go with just a single channel and optimize that as opposed to always carrying around two channels like those early amps. This reduces the size of the amp, making it more portable, and reduces the preamp tube count. We bring the full Treble, Bass, and Middle tone stack controls out, which was only offered on some of the lager amps (Super, Twin). In addition, we add a very versatile ‘Tone Stack’ switch. A lesser known fact is that the preamps in all the blackface models from the 60’s were very similar only differing slightly in the tone stack. As mentioned before, some did not bring out the middle control, but also some differed slightly in a capacitor value in the tone stack. We offer a three position switch that allows you to select the tone stack of your taste. This ends up being a very versatile control to dial in the tone you desire depending on your guitar, speakers, speaker cab, and style of music you are playing. The power and standby switches have been moved to the front for easier access. We offer the SA35 in either a 1×12 combo, or in head form. For the 1×12 combo, we selected the Cannabis Rex Hemp cone speaker. This speaker complements the blackface era amplifiers very well. The speaker has strong, bold volume and presence that can be heard in a band situation, but also has a very pleasing organic tone due to the hemp cone. We offer bias probe taps on the back panel, and a bias trim pot accessible outside the chassis. This allows quick bias check and adjustment with a simple volt meter and without having to remove the chassis. The back panel also has an impedance switch to select between 4 and 8 ohm loads. The combo comes with an 8 ohm speaker, so you can add an additional 8 ohm extension speaker and select the 4 ohm position when running both. When using the head of course, just select the tap that best matches your speaker load. Each amplifier is hand wired in our shop in Raleigh, NC, USA.
