Compact yet powerful, this amplifier is well known for its clear, honest solid-state tone and its ability to handle not only guitars but also keyboards thanks to its neutral frequency response. The design features a real spring reverb, providing deep and warm ambience from a compact unit. The cabinet layout places the power transformer at the bottom for stable power delivery, while the reverb tank is mounted in the upper chamber to avoid vibration from the speaker. The amp produces a natural overdrive when using the OVER DRIVE input, while the NORMAL input delivers clean and articulate tones.
