Additional Signal Sounds listings
"A pre-owned Tasty Chips GR1 in very good condition. It comes with original packaging and accessories.
Manufacturer's description The GR-1 is a granular hardware synthesizer. Creating textures, characteristic sounds, drones, soundscapes, and pads has never been easier. When you are working on a unique sound, it’s always nice to have hands-on controls to easily dial in the sweet spots. The possibility to quickly adjust any parameter of your sound is necessary to adapt to the workflow of any user. Trace every adjustment you make with the built-in 7″ full-color display that is typically only found in top-class synthesizers."

via this Reverb listing
"This legendary drum box has been fully serviced to perfection, ensuring it performs just like it did back in the day, if not better. Don't let the blemishes in it's paint fool you. This TOM Drum Machine has been fully gone through from top to bottom. Nothing has been left to chance. Totally rebuilt to function beyond brand new.
Here's what makes it a must-have:
- Complete Rebuild of Power Supply: Featuring new rectifying diodes, filter capacitors, and voltage regulators for unmatched reliability.
- All New Tactile Switches: Every single switch on this unit has been unsoldered and replaced with a brand new part. Guaranteeing that you will not have a switch fail in the next 30+ years. You will get smooth, responsive, operation. We use OMRON brand tactile switches, the best and built to last.
- Fully Expanded Sequencer Memory (RARE): A rare expansion option from Sequential back in the day, and even more rare now. Very few SCI TOM in the world have expanded sequencer memory. This upgrade more than quadrupled the available pattern storage memory. More room for your beats, making this a highly coveted feature.
- Tauntek TOM16 CPU Upgrade: The famed Tauntek MOD is no longer made. This update to the SCI TOM enhances performance, adding new features to the TOM that allow you to switch the sounds on the fly.
- 16 Internal Sound banks (Cartridges): This modification also builds in 16 expansion cartridges worth of sounds, accessible through the user interface. This upgrade includes all original SCI Factory Carts and the best from DRUMWARE (DigiDesign).
- HKA Designs 'Classics Cartridge': On top of the 16 built in sound banks, the HKA Classics Cart adds eight more cartridges worth of sounds from Legendary drum computers from Oberheim DMX and DX, Linn DRUM and LM-1.
- Printed Manual: A reproduction printing of the original TOM 420 manual that details all the features and functions so that you can jump straight in to producing awesome retro grooves with the famed Sequential drum machine.
- Rugged IP67 Water & Dust proof Flight Case: Your SCI TOM will ship in a custom fit, lockable 🔒 Rugged IP68 💦 Waterproof / Dust-proof Impact Resistant Protective Flight Case. Making sure that your investment arrives to you in ultimate safety and comfort."

"This is not your typical Emulator III. This unit has been meticulously refurbished over dozens of hours, sparing no expense, and thoroughly tested, and is working great. RS-442 interface and external SCSI devices were not tested since we don't have external devices for testing. We see no reason for them not to work but only because we didnt test them, we cant guarantee it. Will be packed right to arrive intact. Will ship internationally."

JOMOX ALPHABASE ANALOGUE DRUM MACHINE MK2
Note: links to listings are affiliate links for which the site may be compensated.
via this listing
Additional Signal Sounds listings
"A pre-owned Jomox AlphaBase in very good condition. It comes with original packaging and accessories.
Manufacturer's description
The ALPHA BASE Mk II is the sucessor of the already legendary ALPHA BASE.
Graphic OLED display
Real RGB LEDs in the sequencer
More buttons: Last Step, Roll/Flam, Store Kit/Patt, Rec Para and Rec Sample
Analogue panning circuitry for the hybrid sample channels
Improved analogue engine
Noise volume is controllable in the hybrid sample channels
More samples
Headphone volume is independent from mix volume
It's true analogue. Eleven instruments, sequencer, Midi/USB/SD-Card. Samples. Sampling inputs, balanced individual outputs.
Although it may appear similar to the classics XBASE 09, 999 and 888, the ALPHA BASE has an entirely new design under the hood. We have put in the concentrated know-how of the Jomox drum machines and of our synths of the past 20 years. We have simplified some things, but also added new components or have combined them new. The outcome is the best sounding and most versatile drum machine that Jomox has ever built."

"A pre-owned ISLA SP2400 in very good condition. It comes with its original packaging and accessories.
Manufacturer's description
For us, the S2400 is a passion project – to recreate the sound of one of the world’s most iconic sampling drum machines, and bring it up-to-date with modern features. The result is the very best of old school and new school technology coming together.
Brad has been obsessed with drum machines for many years – owning, repairing, restoring, modifying countless makes and models (see his HR-16 mods on youtube).
Staying true to form in both sonic characteristics and design aesthetic were the main drivers in the realisation of this project, while bringing the hardware into the 21st Century and keeping the same ‘instant gratification’ and intuitiveness of its spiritual pre-predecessor at heart."

"Like nearly all the high end vintage analog synths we sell, this item has been METICULOUSLY disassembled, cleaned inside and out, FULLY serviced by professionals who’ve been servicing and selling vintage synths and drum machines for more than the last 3 decades, and systematically tested multiple times over a long period to ensure it’s working exactly as it should. No BS. No ebay surprises. We’re perfectionists and don’t cut corners. Although this instrument came to us in relatively good shape, we want our items to be better than the rest and invested *many* hours of tech time plus parts costs to fully overhaul this unit so it would be clean, working like new again and as reliable as possible for its next owner. This was a serious investment of time, love, and money, and was definitely worth the effort and is of course reflected in the higher than usual price. If you’re looking for a great sounding example of this model that works just like it should without needing to invest hundreds or thousands of dollars in tech fees and waiting from weeks to years, this one should make you very happy."

"We paid our tech for the 6.5 hours of skilled labor required to make this Synare work, feel, and sound like new again.
We replaced all potentiometers with new ones for crackle free operation.
Replaced the rubber pad
Replaced transistors 2N3904 x2
Replaced electrolytic capacitors (8)
Cleaned unit inside and out.
Cleaned and lubed switches.
Replaced knobs with a new set.
Replaced the battery snaps.
Cleaned the jack.
In summary, we invested the time and money required to properly refurbish this unit and, as a result, it's functionally the best you’ll find anywhere, and justifiably priced higher than the rest because you won't have to make excuses for a lesser example or pay someone else to do this work and wait who knows how long. The selling commissions we are charged here are added into our prices here."
