Originally, Wurlitzer built amplifier chassis just big enough to fit the components they needed. This left some interior cabinet space unused. There is nothing wrong with this design choice, but there is a lot of interior cabinet space that can be utilized should one (like, say, us) were to design a brand new replacement amplifier to go inside the Wurlitzer.

Whenever you think about modifying a vintage electronic piano, you should think about two things. Is the mod reversible? And, if not, am I actually improving the keyboard?

A Wurlitzer electronic piano has been around for decades. Clearly, Wurlitzer did something right when they manufactured them, because even after all these years they are still desirable. It is important to avoid performing impulsive mods that will irreversibly change the keyboard. Think it through. Consider whether the mod enhances the function of the keyboard. Consider whether there is a less invasive way to reach the same goal.

An effects loop opens up many, many tonal possibilities in your Wurlitzer. Some of the earlier Wurlitzers have a reputation as a one-trick pony. The 112, for instance. How many people on forums have opined that it’s good for that one Ray Charles sound, and that’s it? Three people? Four? That’s not the point. The point is that, once you give the 112 an fx loop, it now has an unlimited amount of sounds.

But what sounds, specifically, should you plug into your Wurlitzer’s effects loop?
