Ahoy! Welcome to your new Depths Optical Vibe Machine! The Depths is our take on the classic optical vibe circuit. Now you can swab the decks with the same lush, pulsating, three-dimensional swirling sound you know and love, with some modern accouterments for all you land-lubbers out there.
The Depths is optimized for use with all kinds of instruments, pickups, and to play well with dirt, so nobody’s left waiting on shore. If it’s got a ¼” output, plug it in and get deep!
In addition to the classic vibe controls, the Depths features unique controls for “Voice” and “Throb.” The “Voice” control adjusts the midrange focus of the Depths, which is perfect for tailoring the effect to your particular instrument. Clockwise, you’ll hear a fuller sound with a low-end focus. Counter-clockwise, you’ll hear a thinner, spikier sound with a forward upper-midrange bite. The “Throb” knob adds a hefty subharmonic low-end pulse to the vibrato signal, which is especially useful on synthesizers and the bass guitar. It sounds great with a little bit of dirt on the neck pickup of a guitar, too! This works best with the “Voice” turned counter-clockwise for a warmer tone.
The Depths’ “Intensity” and “Rate” controls are dialed in to give you the classic optical vibe sound at more modest settings, but dive in deeper and you’ll find anything from a smooth ultra-slow warble to sharp, speedy bursts! Also, the “Level” control has tons of output above unity on tap to combat the perceived volume loss of most vibe pedals, so your tone is always above water. And, if 9v isn’t enough to keep you afloat, the Depths may be powered at 18v for a stiffer tone with more headroom and sparkle.
We've got 2 layouts for you.
Layout 1: We've got the the LFO off the main board to hopefully prevent the dreaded LFO tick. Should fit in a 125b like the original. Downside is that there is more offboard wiring you will need to do.
Layout 2: Slightly larger board, with the LFO on the main board. You shouldn't get any ticking, and you'll save on having to deal with the extra offboard wiring.
