Independent shopping perspective
The Korena take
Built around a pedal-first all-tube platform, the Keeley Custom 12 pairs a gain-pedal-focused preamp and two-band EQ with a transparent effects loop for delay and reverb. Its 25W output drives a Celestion G12M-65 Creamback speaker, while separate Volume and Master controls let you set preamp gain and speaker level independently. The result is a 1x12 Supro combo designed to keep pedals central to the signal path without losing its midrange-forward response.
Strong match
Who this is for
- Pedalboards using gain pedals ahead of the amp, with delay and reverb routed through an effects loop.
- Players who want independent control of preamp gain and speaker sound-pressure level.
