🎸 Crate G-20 Guitar Amplifier — USA Made SLM Era

Classic ’90s grunge / alt / punk solid-state tone — complete bundle

Classic USA-made Crate tone in a compact but powerful practice & recording amp — bundled with original speaker, reverb, line out, tuner, cables, and extras. A true plug-and-play vintage rig with real St. Louis Music (SLM) era grit.

Loud, raw, and reliable, the Crate G-20 is a sleeper classic that delivers authentic ’90s alternative, punk, and garage-rock tone without pedals. If you want real grunge-era solid-state crunch, this is it.

Built in the USA during Crate’s SLM (St. Louis Music) manufacturing era, this 20-watt solid-state combo is known for punchy cleans, aggressive mids, and a gritty overdrive channel that defined countless basement shows, college-radio recordings, and indie releases.

🔊 Tone & Features

• SCG (Super Crunch Gain) overdrive channel delivers aggressive, textured gain — perfect for Nirvana-style rhythm tones, garage rock crunch, post-punk bite, and fuzz-adjacent grit

• Clean channel stays clear and pedal-friendly

• Bright switch adds edge and clarity

• 3-band EQ lets you dial in warmth or bite

• Built-in spring-style reverb adds space without washing out your tone

• Headphone out & line out make this ideal for home recording, rehearsal, or apartment playing

Don’t let the size fool you — this amp gets LOUD for a 20-watt solid-state combo.

No tubes. No fragile parts. Just dependable, American-made grit.
