Salut everybody,

yesterday I was at a concert with Ulf Wakenius (Wes Montgomery tribute) and checked the tiny 8" amp he played: http://www.lundgaardamps.com/page6.html

It was the loudest jazz-concert I've ever been to. And now i know why:

"For bass and other power demanding instruments like a jazz guitar, choose the 550 or minimum 300 watt version."   :loco

they use IcePower class-d modules.

Salut everybody,

I am playing a SansAmp TRI-A.C. through an elder QSC-PA amplifier (USA 360, bridged).
To get rid of the very heavy (but very powerful and reliable) QSC I would like to use one of these modules

http://www.hypex.nl/product/ucd-amplifier-modules/ucd400hg.html

together with the recommended switchmode power supply.
Does anybody ever used an UCD400 or UCD180 as a guitar power stage?

Are there any commercial guitar-amps in class-d? Like Crate's PowerBlock with the TDA8920B? On the datasheet of the successor TDA8950 no pro-audio applicatons are recommended. Do they have reliability issues?

Greetings,

Michael
