"Super rare analog synth Pulser/Hillwood/Multivox M-75/Mx-75.

Good working condition.

One of the preset switches is little unreliable in one position, works, but little cleaning would improve the reliability."

Roland JD-XA Keyboard Synthesizer

"Roland JD-XA—arguably one of the most unique synths ever built. You get 4 true analog parts + 4 digital parts, lush filters, deep modulation, killer sequencer, and hands-on control that makes this a sound designer’s dream. Zero issues, zero wear—looks and plays like new."

OB-Xf - a great sounding Oberheim from the Surge team


video upload by abominable music

"OB-Xf is an open source (GPL3 license) project from the Surge team aiming to recreate the sound of the classic Oberheim OB-X. Available as a standalone application on macOS, Windows, and Linux (VST3, AU, LV2, CLAP formats). Building on existing work from 2DaT and discoDSP (OB-Xd) and still in Beta, this can be downloaded from the developer Github repo: https://github.com/surge-synthesizer/...
The synth doesn't have effects, I'm using Valhalla Supermassive for reverb in these demos

My custom patches are available for free on my KoFi page: https://ko-fi.com/s/6419dc9bea"

The über-quirky, but fun Memorymoog sequencer explained | Synth geeks are strange people


video upload by Espen Kraft

"Memorymoog plus. Polyphonic and monophonic sequencing with CV & Gate old school and tons of fun. Syncing the Memorymoog can also be a challenge."

Chase Bliss: Generation Loss MkII Model Demo


video upload by MKustomAudio

"The ‪@ChaseBlissAudio‬ 'Generation Loss MkII' pedal simulates the sound of tape while offering a number of different models (EQ profiles based around physical hardware) for wide ranging results. To demonstrate the possibilities, full mixes of short ambient tracks I’ve previously posted were used. After setting the secondary/hidden settings and the DIP switches, a MIDI controller [NOVATION LAUNCHKEY MINI 37 MK4] was used to turn on/off the pedal and adjust the main parameters."

Music gear Santa heard you were good this year, so he finally dropped what you've been waiting all 2025 for: Reverb's best-selling gear of the year lists.

From the nostalgia-driven electric guitar cohort and demand for artist signature pedals, to the battle between amps and modelers and much, much more, Reverb's data-based rundown not only features an editorialized look at some of the top categories, but allows musicians to dig into the data at every level, from the best-selling pedals released in 2025, to the best-selling electric guitars of the year, new or otherwise.
