I've used the madamp A15 now with several bands varying from Neil Young to 80-s rock/metal.
With all concerts I get complimented with the sound coming from the 2 x Celestion G12H, powered by the Madamp
(with a master volume and a 50W MOSFET Poweramp attached to the OT)
So hereby I want to thank Martin and all who contributed to this forum.
The audience never lies and they love my madamp
