Teaching Machines Wellspring Reverb Review

The Teaching Machines Wellspring stereo spring reverb has been making waves in the pro audio world since its launch and I’ve finally had the pleasure of my first dive deep into this remarkable unit.

The name Wellspring evokes images of a refreshing source, an origin from which you could reasonably expect soundscapes to flow freely. The Wellspring isn’t just another reverb unit; it’s a complete effects rig on its own and a constant river of inspiration.

I initially tried it with my Soma Terra and also with guitar and it’s certainly capable of sounding smooth and sweet. I could’ve lost a great deal of time enjoying playing guitar through it, but inevitably I wanted to see how it reacted to more aggressive treatment and plugged a Korg KR-55B in. To begin with I did things ‘right’ – going into the rear/line inputs and it sounded excellent – the delays/filter/modulation allowing all manner of rhythmic options and tone sculpting. So far so good. Then I tried plugging into the guitar input on the front and unleashed a world of grit, noise and dirt (which of course I loved): this is my kind of machine.

This lead me to think ‘if only a Grampian 636 had all these features and was stereo’: so I duly plugged the Korg into my Soundgas Type 636P preamp pedal and things quickly got super gnarly. At last, a stereo Grampian with all the bells and whistles I could wish for (a pleasant surprise for someone who usually wants more options from his gear).

The delays are excellent and can get very crunchy; the filter is wonderful for subtle (and not so subtle) tone shaping; the modulation helps to smooth out any ringing from the springs (and can be a more creative option also); finally, the Magic feedback knob can introduce screaming/howling feedback if over-used, but can also evoke otherworldly sonic atmospheres.

The ensuing deep dark and dirty jam lasted half an hour and could’ve gone on all night had I not needed to get some sleep before an early start the next day. In short, this is a one-stop effects unit that is as rewarding for someone just starting out with hardware as it is for someone (like me) who already has a studio full of gear.

Whether you have heard it all before or are just starting out on a sonic journey into hardware: for anyone seeking more than just a reverb, the Wellspring is for you. But remember, with great power comes great responsibility – especially when playing with the MAGIC feedback loop.

As always, I’d recommend not just reading about it but diving in and experiencing the Wellspring for yourself. After all, the true joy of these devices can only be understood when you’re lost in their depths.

Happy sonic explorations!
