Dumble Overdrive Special: 2 Headshell

Head — a strange word for this, but it is what it is called — the amplifier itself, presumably sitting on the ‘body’ represented by the stacks of speaker cabs. Using a schematic from the ampgarage.com forum as a base I set out to do some good and honest woodworking, always relaxing. First, getting small pieces of 18mm plywood is no joke; I ended up with an incredibly massive piece for the same cost as if I had shopped where smaller pieces are sold. So I guess I am building some more speaker cabinets from that next.

A quick box later, lots of sanding necessary, I noticed the plywood carried several empty pockets revealed when cut. As a result mixing up sawdust and woodglue creates a good putty of sorts to fill those gaps.

As most chassis available vary slightly in size its importent to tweak the measures to your specific one. Also keeping the ratios is important if you want the look to be the same of the original fumbles. Plenty of builds out there have off putting ratios that immediately signals a poor job.S

Some photos of the woodworking almost finished.

Happily the fit is good.

And so is the final case, glad of how it turned out. Although I’m sure I’ll revisit some minor details in the future it certainly is better than those custom orders availible on the market, with better hardware and hopefully durability.
