Mooer Micro Preamp 003 Power-Zone, new.
"The Powerzone is a preamp based on the powerful metal tones from a Koch PowerTone amp.
Mooer Micro preamp
Mooer analyzed 10 famous tube amps and created these pedals based on those popular sounds to create these preamps/DIs.
If you plug into the effects return of any tube amp, that amp will morph into the Mooer pedal of your choice.
You can also use the on-board cab sim technology to plug directly into a PA system or recording interface without having to use an actual amp. This gives you a very direct sound, but the cab sim makes it sound like a professionally mic'd up speaker cabinet. And fortunately, you can turn the cab sim off if you want to run into your cab emulator
Essentially this means you can gig with a pedalboard and no real amp which means no more breaking your back carrying that heavy 2x12 combo around! And it's easy to great guitar tones.
You can also use these preamps as a simple overdrive pedal into an amp. Turn the Cab Sim off (Because you wouldn't want cab sim into an actual cab) and run it as you normally would in your signal chain."
