Product Details
✓All-in-One Guitar Effects Station: GEM Box II combines 8 effect modules, 66 effects, 23 drive sounds, 7 amp simulations, rhythms, looper and expression control in one compact processor for electric guitar practice, tone learning, jamming and rehearsal backup.
✓80 Presets Plus Editable Patches: Start quickly with 80 factory presets, then edit and save up to 80 user patches for clean, crunch, rock, metal, lead or ambient playing. Fine-tune patches to match your guitar, amp or headphones for a more personal sound.
✓180s Looper and Rhythm Training: Record riffs, chords or song ideas with the 180-second looper, then practice leads over your own loop. Add 40 drum rhythms, 10 metronome patterns and Tap Tempo to improve timing, groove, solo practice and songwriting ideas.
✓Built-In Expression Pedal Control: Use the onboard expression pedal as volume control or assign it to supported parameters such as wah, gain, pitch, modulation depth and reverb decay. Great for practicing dynamics, lead parts, swells and real-time tone changes.
✓Flexible Connections and Power: Select TO AMP for guitar amplifiers or LINE OUT for mixers and audio interface line inputs. AUX IN lets you play along with external devices, the stereo output supports headphone practice, and the unit runs on a compatible 9V DC 300mA center-negative adapter or 4 AA batteries.
