Line6 Catalyst 100 100W 1x12" 2-Channel Guitar Amplifier

Catalyst 100 100W combo for stage and studio

The Line 6 Catalyst 100 is a 100-watt 1x12" dual-channel guitar amplifier built for electric guitarists who need a single amp that works equally well on stage and in the studio. It delivers 100 watts through a custom-voiced 12-inch speaker and offers six original amp designs crafted with HX sound design techniques. A 4-in/4-out USB audio interface and XLR direct output with ground lift handle recording and live sound reinforcement without extra gear.

Replaces separate modelling amp.

This combo consolidates a modelling amplifier, 18 built-in effects covering delay, modulation, pitch, filter and reverb, plus a multi-channel USB interface into one enclosure. The jump is worth it when you want six distinct amp voicings from pristine clean to modern high-gain, per-amp boost circuits, tap-tempo control, MIDI capability and power attenuation for silent practice, all without patching multiple boxes together. Buyers who need more than two independent channels or a second speaker cabinet for stereo operation should look elsewhere.

Standard combo placement

Setup is straightforward: position the 31.97 kg cabinet, connect power and guitar, then use the front panel or the free Catalyst Edit app on desktop or mobile for deep editing. The effects loop, power amp input and MIDI ports follow conventional wiring, so integration into existing rigs is familiar. The main friction point is the weight; lifting the unit onto a stand or into a vehicle often requires two people, and the optional LFS2 footswitch is sold separately for hands-free preset changes.
