The wide, crystalline headroom of a Fender Twin-inspired clean meets the drive and definition of an SLO 100-style overdrive.

American clean.
Hot-rodded overdrive.

Two distant references brought together in one head, without forcing either channel to compromise.

The Twin-Slo pairs an open, deep clean with generous headroom to a dense, defined and responsive overdrive channel. Independent volumes and tone controls make it possible to build two genuinely different sounds within the same amplifier.

Twin clean · SLO drive

Two channels.
Two true identities.

The clean channel prioritises extension, dynamics and transparency, leaving room for the guitar and pedals. The overdrive channel draws from the SLO 100 to deliver saturation, sustain and articulation even at substantial gain levels.

Presence and Resonance act on the power-stage negative feedback, allowing brightness, attack and low-frequency depth to be shaped independently.

  • Independent volume and EQ for each channel
  • 50-watt 2× 6L6 JJ power stage
  • Presence and Resonance controls on negative feedback

Minimal shell · Visible technology

Carbon look.
Tube glow.

The minimal carbon-look enclosure leaves the electronics visible and turns the valves into part of the amplifier’s visual identity. Purple lighting enhances their presence without concealing the construction.

The RL Technology effects loop is entirely tube based and uses a 12DW7, combining an ECC83-equivalent section and an ECC82-equivalent section within the same envelope. The high-gain ECC83 section recovers signal level after the effects chain, while the ECC82 section operates as a low-impedance cathode follower, providing a 40 kΩ interface impedance.

  • Compact carbon-look enclosure
  • High-gain recovery through the ECC83 section
  • ECC82 cathode-follower buffer with 40 kΩ impedance
