Based on the GDS 18 Watt Marshall Clone
Got many compliments on these when used with Celestion Vintage 30s - which is what I ran in the Fender Cabinet when I was using this head at gigs. Don't let 18 watts fool you - they are loud. There is no signal loss due to reverb or design quirks - its a full Marshall type tone. I added a Presence Control in back to give it more overall high end distortion which really brought out the sweetness of the EL84s and gives the amp a sound like its bigger cousins have.
Both DerStevers have gone out into the world and is giving their new owners much joy.
