Marking our 20th Birthday the Mark Four Orton is our first aesthetic upgrade of the amplifier and is how it stands today(2017). We had also made some tweaks under the lid, which some lucky users will have enjoyed in the last few Mark three versions made as we were phasing out production of the older casework. The main visible change on the amplifier itself was that the buttons were now polished metal. Other refinements on the main body included subtle machining improvements on the front panel and an upgrade for the binding posts at the rear of the amp.

The biggest change externally was to the remote control handset. This was now a fully machined aluminium and stainless steel object with stainless steel buttons. An added touch was the inclusion of an LED torch for those wiring up moments when you can’t see the back of the amp on the rack.

An Eye fi festival.
