MadeOnEarth - LedRover Analog Stereo Distortion Pedal
MadeOnEarth - LedRover vs Dfam video upload by Isak Eliyahu
Press release follows:

LEDROVER: ANALOG STEREO DISTORTIONThe LedRover is a 100% analog stereo diode-based distortion effect from MOE. It originated from our quest for the ultimate distortion effect for the TB-303, finalized after a year of experiments with various components including diodes,
LEDs, germanium, and custom potentiometers. The inspiration for the circuit came from a famous filter resonance design that we discovered uses diodes in the feedback loop, which creates a round sound with a distortion tone that can be aggressive while remaining musical and preserving the character of the original signal. Based on this, we designed two distortion modes for the LedRover using different diode placements. Following extensive calibration for synthesizers and drum machines, we have ensured the effect is suitable for a wide range of applications—from kicks and snares to cymbals, bass, and leads—offering everything from delicate warmth to extreme distortion.
The integrated Tilt filter was born from our understanding that filtering before overdrive is essential for emphasizing frequencies pleasant to the ear. Unlike standard Tilt filters that typically offer a 6dB/Octave slope, we designed the LedRover with a steeper 15dB/Octave slope for both low and high frequency ranges. This ensures the signal enters the distortion with high saturation, allowing the circuit to mangle the sound even further. We selected the reference point for the filter through trial and error across a variety of gear to emphasize mid-range frequencies rather than just extreme highs, providing a flattering response for the distortion circuit.
Additionally, we added an x10 Boost button to push instruments with weak outputs hard into the Tilt filter. This creates distortion right at the entrance of the filter, which can be controlled delicately with the input knob; as you attenuate the input volume, the action of the filter becomes significantly more pronounced, while higher values create a unique op-amp saturation that works in perfect synergy with the diode overdrive. We build the LedRover to the highest standards of reliability and feel, housed in a custom aluminum box with resilient UV-printing and custom potentiometers.
Feature List:
100% Analog Stereo Diode-Based Colorful Distortion Circuit.
Dual Distortion Modes: Two distinct distortion characters.
Custom 15dB/Octave Tilt Filter.
x10 Boost Switch: Push weak instrument signals and overdrive the Tilt filter op-amps for additional colorful harmonics.
Two-Mode VU Meter: Visual monitoring of the wet and dry signals.
Dedicated Input and Output Controls.
Buffered Bypass.
High Standard Build Quality: Custom aluminum box with resilient UV-printing and custom potentiometers.
Compact Form Factor: W: 12cm (4.7") x D: 10cm (3.9") x H: 5.5cm (2.2").
We are very excited to officially debut the LedRover and our beloved Analog Chorus 60 at Superbooth in Berlin, Booth B048. We will have a demo station equipped with two sets of headphones, but you are also welcome to connect your own.

GHOST pedal vs 303 shootout with new V4 Firmware Update
video upload by Endorphin.es
"New GHOST Pedal V4 firmware update available now:
https://www.endorphin.es/modules/p/gh...
TB-303 ready: added a more 'squashed / pressed' response so acid lines feel dense and consistent, with better note-to-note stability
cleaner high-gain: reduced hiss and unwanted artifacts at extreme drive settings while keeping the same aggressive maximum gain range.
more musical dynamics: improved touch response and transient control so the drive feels more alive instead of flat
new 'Fairfax'-style, asymmetrical drive character: smoother, more amp-like breakup with a tighter feel and richer mid harmonics
dive more stable at high sample rate (96 kHz): optimized oversampling/filtering for premium distortion quality without CPU spikes.
What type of drive is it? It’s a high-gain soft-clip overdrive / distortion: amp-like saturation at lower settings, and full distortion territory at high drive with smoother harmonics and more sustain.
hall reverb is lusher: denser diffusion + more modulation depth gives a wider, more spacious 'big hall' feel
predelay for all reverbs is smoother: knob adjustments are cleaner with fewer artifacts while turning.
reverse reverb is more polished: improved wet shaping and saturation for smoother, more musical reverse tails.
spring stereo behavior improved: more consistent left/right output and a more natural 'drip' feel.
more stable LRRL and LRLR taps behavior: they pass properly thru the LP/HP tone filter inside the delay tank
creamier resonance: resonance behavior is more musical, with less clipping at extreme resonance sweeps.
comb filtering smoother when tweaking: reduced zipper/crackle when moving controls; more stable, playable comb textures.
delay: 7/4 divider changed to 3/8 (=dotted 1/16), 5/4 divider changed to 2/3 (=triplet 1/4). Meanwhile 3/4 = dotted 1/8, 3/2 = dotted 1/4, 1/3 = 1/8 triplet are working as is
dividers knob action inverted to properly match the scales around the knob
dry and wet properly phase aligned with less chorusing - still any MIX with filters applied may cause phasing effects which are unavoidable
hall reverb is selected after soft reset (to defaults parameters)
fixed an issue where very fast MIDI preset switching by Program change could cause the pedal to freeze."

Click the auction link on top when you get there for additional listings.


"This collection of vintage synthesizers has grown with me for years. Most all of these instruments have been used on many projects, including VeggieTales, a variety of remixes, and many PlayStation video games and marketing and promotional discs. Most recently they were used on the Mass Effect Andromeda video games soundtrack. They have also been sampled and are part of the SoundVault Collection and the Kurzweil Analog Collection for the K2000 series samplers.
VEMIA note: to forestall many inquiries, The seller’s idea is that he wants to sell it as a whole. That may or may not work out in this auction. If it doesn’t, obviously he’ll be free to do whatever he wants after the auction finishes.
It all works. Everything has been kept in a clean, smoke-free, climate-controlled studio. I have always fixed things myself, so everything is operational and sounding great. I have repair notes on the synths that received attention, though most of them have worked great over the years, without much need for repairs. There are also several MIDI to CV converters so they can all be controlled by computer, plus cables if desired. And a few have cases and manuals.

Rodec Sherman Restyler
video upload by Robin Rimbaud-Scanner
"A little studio playtime with the rather rare Rodec Sherman Restyler, a Roland TR-6S drum machine, and Roland TB-303 software. The Rodec Sherman Restyler is a stereo analogue filter effects unit developed as a collaboration between two Belgian companies: Rodec, known for high-end DJ mixers, and Sherman, creators of the legendary Filterbank. It combines the hands-on immediacy of a DJ tool with the raw, aggressive sound-shaping power of classic analog filters. It can get very nasty, but I kept it under control here.
I'm surprised that there are so few videos on this extraordinary playable filter too, so hope you will enjoy it 😃"

Bad Gear - The OG
video upload by AudioPilz
"Welcome to Bad Gear, the show about the world’s most-hated audio tools. By now it must have dawned on even the most terminally online late GenX/early millennial person that calling something The OG is cringe.
Today, however, we are going to talk about Novation Bass Station. This 1993 mono synth and predecessor to the incredibly popular Bass Station 2 is more than deserving of the title because A - it was one of the most important heralds of the 90s analog revival and B - it even got a little shoutout by The Wu Tang.

"The TB-303 is undoubtedly the most cloned synth ever - but clones are clones. DIN Sync call their RE-303 a replica, with some justification.
This was professionally made with correct components, and from the correct era. It's like having an original TB-303 which hasn't been played to death - and has well-featured MIDI in addition. My example is not quite mint, but seriously beautiful.
Comes with a UK external power supply - it needs to be well-regulated and to spec.
VEMIA can collect and pack (9GBP) for onward shipping / delivery."

Alien 303 V2 (MONO) vs. Alien 4DX (Binaural space 3D Sound) | Acid Evolution Comparison
video upload by G-Sonique
"Alien 303 V2 (MONO) vs. Alien 4DX (Binaural space 3D Sound) comparison
Is Mono Acid dead? 🛸 In this video, we compare the legendary Alien 303 V2 with the groundbreaking Alien 4DX Binaural Topology synthesizer.
While traditional acid synths are usually mono and "flat," the new Alien 4DX uses a special 3D binaural topology that emulates analog circuits and DSP chips to place the sound directly in a 3D/4D space around your head. No quadraphonic setup needed – just your headphones or 2 speakers.
What’s the difference?
Alien 303 V2: The classic, punchy, '2D' mono acid lead that defined a generation.
Alien 4DX: A massive, organic, and harmonically rich sound that fills the entire stereo field using psychoacoustic principles (time shifts, phase distortion, and frequency modulation).

Acid - Novation Circuit Tracks Sound Pack by A Force Truly Evil
video upload by A Force Truly Evil
"Available here: https://sci-fiaudio.com/product/acid/
YOUR NOVATION CIRCUIT TRACKS — REBORN AS A MODERN ACID MACHINE. FROM TIMELESS ACID HOUSE TO RAVE TECHNO
ACID transforms your Novation Circuit Tracks into a modern Acid machine, designed for genres such as Classic Acid, Acid House, Techno, Detroit Techno, Acid Techno, Hard Techno and Rave genres.
Roland TB-303 behaviour emulated — with a more modern sound, yet fully capable of delivering the classic tone. Modernised and expanded.
The pack includes 128 patches in total:
96 authentic 303-style Acid sounds plus 32 additional sounds, including a strong selection of polyphonic material such as chords and classic genre sounds to expand your productions beyond classic monophonic Acid lines.
All patches respond to velocity where appropriate, allowing expressive control and dynamic performances directly from the Circuit Tracks pads.
The 303-style patches are programmed to recreate the behaviour and response of the original machine — from timeless Acid House to harder Acid Techno and underground rave territories — featuring velocity-based accent behaviour, glide response, LFO modulation for evolving movement, and powerful modern distortion algorithms with delay and reverb send effects.
Completed with 64 drum samples (House, Techno, Hard Techno, 707, 808, 909 and more), ACID becomes a complete production toolkit — effectively turning Circuit Tracks into a purpose-built Acid production machine."
