Peter wanted a WF-55 combo, but with the valves pointing down instead of forwards. So he did a bit of metalwork, as shown here.”What a beautiful amp. The tone is lovely and it is virtually noiseless. As promised I have attached some photos to show how I built it, using the supplied chassis, so that it can be fitted into a cabinet vertically. I would recommend this kit to anybody as it has a lovely clear and crisp tone that even handles a bass guitar perfectly!”
