All Tube Stereo 120watt (60watt per side) 2 channel guitar amplifier with built in chorus.
Comes with FS6 footswitch.
The S120 Reissue was designed in 1986 and is the flag ship of the early M&S series. In the late 80’s & early 90’s, The M&S series have been used by players such as Robben Ford, Saigon Kick, Skid Row, John Sykes, Ted Nugent, Rudolph Schenker, Michael Schenker and Chet Atkins.
The S120 Features 2 independent channels, Reverb, and Chorus.
Channel 1 features the SL voicing of our famous TBR series rack series amps for ultimate “Old School” metal (think Iron Maiden, Judas Priest, Scorpions). Back off the gain, add chorus and reverb and you have a Gilmour or Eric Johnson tone, right out of the box!
The S120 has a Lo and Hi sensitivity input. To provide greater versatility, many controls feature additional performance when pushed or pulled.
Channel 1 features two gain boosts. Pulling the Bass control activates Gain boost stage 1. Pulling the Treble control activates Gain boost 2. Channel one also features a Mid-notch when pulling the middle control.
Channel 2 features a treble pull bright, Middle pull notch and a Bass pull contour. The Mid-notch allows you to go between a blackface to tweed type of tone. The Contour control increases the bass response, while compressing the midrange and giving a gentle push on the high-end.
Channel 2's Master control features a pull for power amp boost.
The 3 spring accutronics Reverb and Chorus features are both footswitchable. The Chorus features a Speed and Depth control. When pulling the Depth control, a presence boost is activated.
The S120 was the first Tube guitar amp to offer a true stereo effects loop with send and return controls. The effects loop is post-preamp and pre-power amp and also foot switchable.
A Rivera exclusive feature, Slavemaster is a separate third channel. Slavemaster simulates having a big amplifier powered at full blast through load resistors which produces output stage distortion and serves the function of a power attenuator. The Gain and Level controls function similarly to Volume and Master controls on an amplifier.
Slavemaster also has its own effects loop on the rear panel, so you can have individual effects just on the Slavemaster channel for that “step on lead” sound.
Rear Panel Features
Controls on the rear panel include the power class switch (pentode/triode) which changes the nature of how the tubes operate as well as how the signal flows through the amplifier.
This can vary the sound from silky and soft in the Triode setting to a full power brightened tone in the Pentode position. Rear Panel Jacks include: two parallel speaker jacks, line out, Effects Send and two Returns, Slavemaster Send and Return, and the Footswitch connectors. Stereo Patch Panel wiring gives you the option of running a Combo Amp in true stereo with one amp driving each speaker, or running both speakers together in mono.
Available in a Top configuration only.
