Plexi-style British drive with a modern twist. The Mooer 018 Custom 100 Micro Preamp is modelled on a 100-watt, plexi-based boutique signature amp. The clean channel covers American shimmer and UK warmth; the drive channel is classic British with a huge gain range. Like every Mooer Micro Preamp, it has two channels, its own speaker cabinet simulation and two footswitch modes – all in a tiny metal box.
Why customers choose it
- Real amp character: modelled on a 100-watt plexi-based boutique signature amp – a great all-rounder
- Two channels: clean and drive, each with its own 3-band EQ, gain and volume
- Play direct: switch the cab sim on to connect to a sound card, powered monitor or PA – no amp or speaker cab needed
- Use with your amp: or switch the cab sim off and feed a power amp or your amp’s effects return
- Takes no space: micro-size pedal for any board
Who it is for
Guitarists who want a specific amp sound on a small board, players who record at home through an audio interface, and gigging players who plug straight into the PA at church, college or club shows.

Good to know
- Power supply is not included – use a 9V DC centre-negative adapter that gives at least 300 mA (Mooer recommends its Micro Power).
- For delay, reverb or modulation, put those pedals between the preamp output and the power amp or effects return.
- This is a preamp only – it has no built-in delay or reverb, even though the maker’s spec list mentions them.
FAQ
Can I use it without an amp?
Yes. Turn on the cab sim and connect to an audio interface, powered monitor or PA.
Can I use it with my own amp?
Yes – into a power amp or the effects return of your amp. Mooer recommends a tube power amp for the best result.
