There’s still one UNDERTOW floating around here, ready to ship.

The Undertow is a PT2399 based modulated delay inspired by the Mid-Fi Pitch Pirate Deluxe. It can go from warm, warped repeats and subtle movement to unstable, pitch-bending, broken-machine weirdness.

Dial it back and it can be surprisingly musical. Push it harder and things start getting beautifully wrong.

Hand built by Third Floor Effects.

$135 + shipping.

Ready to ship.

I’ve got 2 Third Floor Effects devices built, tested, and ready to ship.

$135 each.

Both are hand built, one at a time, right here in Texas. If you’ve been wanting to grab one, shoot me a message. Once these two are gone, I’ll be back at the bench building the next batch.

UNDERTOW $135

Got another one ready to go.

The Undertow is built around a PT2399 delay chip, with the topology heavily inspired by the Mid Fi Electronics Pitch Pirate Deluxe.

This thing is just flat out fun.

It can do warped delay, nasty pitch movement, strange modulation, seasick textures, broken record type sounds, and plenty of weird stuff in between. You can keep it somewhat under control, or turn the k***s and let it completely fall apart.

And with the right settings, it can actually be very musical too. There are some really cool subtle modulation and delay sounds hiding in it when you dial it back. So it can go from usable, musical movement all the way into complete warped out insanity.

It is definitely not a clean, polished digital delay. The PT2399 is being pushed around on purpose, and that is where a lot of the character comes from.

If you like weird pedals, noise, ambient stuff, experimental sounds, or just want something that does not sound like every other pedal on your board, the Undertow is a good one.

Another AFTERLIFE is finished, tested, and ready to ship.

The AFTERLIFE is my take on the Life Pedal, but miniature, combining Rat style distortion, an analog octave up section, selectable clipping, and a separate boost in one compact pedal.

Heavy, nasty, and built for big riffs, doom, sludge, and anything that needs to get absolutely crushed.

$140. Hand-built by Third Floor Effects
This one is ready to go. Message me if you want it.
