Line 6 Spider V 20 MkII Modeling Combo Amp — Practice Power with Pro-Level Tones

The Line 6 Spider V 20 MkII is a 20-watt single-channel modeling combo amp designed as the ideal practice rig for guitarists who want a universe of tones in a compact, desk-friendly package. Plug in to rock one of the 16 diverse presets or dial in a personalized sound with color-coded controls—this model brings the depth of Line 6's top-tier processors to an affordable practice amp. The YRS-23 is well-suited for bedroom players, students, and gigging guitarists who need a portable backup with serious modeling capability.

Standout Features That Set This Combo Apart

Classic Speaker mode marks a significant upgrade over the original Spider V 20. By deactivating the high-frequency driver and cab/mic modeling, it delivers an authentic, traditional amp response. Effects are easy to toggle in and out stompbox-style using the dedicated FX buttons. Through the Spider V Remote app, access to 200+ amps and effects from the CustomTone community is unlocked.

Tone Engine and Preset Architecture

Inside, a modeling engine leverages decades of Line 6 amp-modeling development. Players access clean, crunch, and high-gain voices as well as acoustic guitar and bass presets. The 16 onboard presets cover classic amp tones, Artist signature sounds, and Iconic Song recreations. Optimized amp and effect defaults make custom tone creation approachable even for newcomers.

• Number of Channels: 1 — simple single-channel design for quick setup
• Power Output: 20 W — enough for home practice and jamming in small spaces
• Preset Count: 16 onboard / 200+ via app
• With over 100 effects models, up to three can be layered per preset for creative sound design.

Speaker, Cabinet, and Physical Design

A custom 203 mm (8-inch) full-range speaker is fitted in a poplar plywood cabinet with black textured vinyl, ensuring a lightweight yet sturdy build. This full-range design enables the amp to double as a monitor for acoustic guitar, backing tracks, or full mixes. When Classic Speaker mode is engaged, players experience a genuine guitar-cabinet voicing.

• Speaker Configuration: 1 x 203 mm (8") full-range custom speaker
• Cabinet Material: poplar plywood with black textured vinyl covering
• Dimensions: 386 mm H x 361 mm W x 203 mm D
• Weight: 5 kg (11 lbs) — lightweight and gig-ready

Connectivity, Controls, and Recording

Front-panel controls cover Drive, Tone, Volume, Reverb, FX level, Save, Preset selection, Tap/Tuner, and Master Volume. Three color-coded FX buttons allow instant effect engagement. A Micro USB-B port acts as a class-compliant audio interface for computers and mobile devices. The 3.5 mm Phones output mutes the speaker for silent practice or serves as a stereo output when using a TRS cable.

• Reverb: Yes — independent front-panel Reverb knob
• The headphone output (3.5 mm stereo jack) can be used for silent practice or as a direct output for recording.
• Footswitch Input: No
• USB: Micro-B for audio interface, firmware updates, and app control
• Battery Powered: No — standard IEC AC cable operation
