Hi Mick,
well .. in fact the picture with the Glockenklang is the only one which was made by the previous owner of the MK Std. I used to play a Glockenklang too but - belive it or not - sold it for a SWR megoliath which I prefered after A/B-ing it vs. two Take Five cabinets. My MK Std goes into an Alembic F-1X Preamp, a TC TripleC Compressor (which I am using less and lesser) an finally a QSC RMX-2450. The Power from the QSC is absolutely overkill but the sound and the dynamic tops everything I've heard so far.
