Your New Favorite Synth Dealer
After years of great success in the vintage synth restoration business, Rosen Sound is proud to now offer quality synthesizers for sale to the public under the moniker of Rob’s Rare Synths. Alongside dealing in goods, we’re also able to buy your gear whether it’s one piece of gear or an entire collection.
What’s So Rare?
Simple! Our gear works, actually has the work described performed, and comes with the most killer warranty in the biz. Additionally, you will not deal with unscrupulous characters, and you will have direct contact with the business owner who communicates using his real legal name. Can you imagine wiring thousands of dollars to someone operating under a pseudonym? We can’t either, and we’re here to change the game.
What’s For Sale?
Everything we have available for purchase or pre-order is listed below. We update the list when possible and also add SOLD to the listing as soon as something sells.
Check out our Reverb store as well but we have recently seized listing most things there as this webpage has been a better source of sales for us.
Most of our synths listed below are restored-to-order, however have already had preliminary servicing done to them so we can offer them for sale. This means they’ve been gone through to ensure they can be completed in the lead times provided below and be considered fully restored instruments worthy of their price and our lifetime warranty.
ARP Solina String Ensemble – Unit will be in new walnut case, otherwise in average condition as these usually all have their writing rubbed off etc. All offers considered. Great candidate for extreme restoration which we can do for you.
ARP Axxe – Unit in okay shape. Prime piece for modding it to your liking. $1500 and 90% of that will be donated to a Black Lives Matter associated charity/fund. 3-4 week lead time.

Oberheim Four Voice FVS-1 – When it rains SEM’s it pours I guess! Another Four Voice is being prepped for sale and if you missed out last time, don’t miss out this time!

It is undergoing a full restore including all new CMOS chips on the programmer and poly keyboard assigner, a full recap and the general rebuild we are known for on these units.

Below is our B-Stock list. Through our years, we’ve collected some pieces we cannot offer for full value because of strictly cosmetic defects. This means they operate as good as the pieces in our normal stock list, but may have above minor to notable cosmetic defects. These pieces are great for those who want the vintage sound without paying the premiums we are known for. The same warranty applies to these of course.
No B stock synths are available at this time
We go absolutely nuts restoring our synths. For most machines, they’re completely stripped down and cleaned out. Following that, each board is inspected and failing or problematic components are replaced for maximum reliability without any detriment to the sound of the unit. Our years of experience restoring these machines has bestowed us the knowledge to know what fails the most, from certain capacitors and resistors, to CMOS and op amps, etc. With that said, we guarantee the synthesizer to be free from work related defects for as long as you own the machine. Not just for 30 days or 3 months like other dealers. If you own it, you’re covered.
Whats not covered is negligence, accidents, and problems related to aging. This is vague, and unfortunately there is no way to draw a hard line on what qualifies as age related and work related issues. This gray area is where we excel in customer service. We stress that this is why it’s important to deal with honest and reasonable people, which we are. We can’t predict the future, and neither can you. Science says even brand new components can fail suddenly. If this is the case for your purchase, we’re happy to help you. If it was something we may have missed, there’s no charge. If it’s something age related or what we call “random acts of science”, you’ll also still be helped, potentially just for the cost of the part, assuming that part doesn’t cost $0.50 like most parts inside synthesizers.
Want To Sell Us Your Gear?
RRS is well financed to purchase one synth or an entire collection of them. The selling process is simple: just email us with what you have to sell and please also include an asking price. If you can’t think of an asking price, that’s fine, we’ll still be happy to make an offer.
We are not interested in purchasing gear for full value that you got fixed elsewhere.
A note on offers:
Our prices reflect the countless hours we invest in the gear we sell.
We believe we pay exceptionally fair (to you) prices for broken gear. That said, we are not in this business to spend a lot to make a little… Nor are we in the business of ripping people off for their valuable gear… Nor are we in the business of “flipping” gear for more than we paid for it without doing any work to it. Other sellers see our pricing and sell the same models at our prices with considerably less work and “future proofing” done to the electronics. We take pride in what we do and price accordingly, putting our reputation on the line every time we sell gear. Please understand the offer we make or accept for your gear will reflect “the road ahead” for us, and not the often higher-than-usual prices listed here.
Sell to us if you want a fair price and the peace of mind that the gear will be taken care of by professionals, put into the hand of artists, and when they’re done with it, well serviced (as we call it, “good gear”) will continue to circulate for time to come on the used market, which is good for humanity.
Consignment & Brokering
“Can you sell my gear for me?”
…The short answer is yes. The long answer is you may be better off just selling it to us or selling it on eBay (though eBay and Reverb come with their own set of risks in that the system is a bit bias’d against sellers). We operate consignments on a strict and little-wiggle-room fashion simply because consignment really isn’t the best idea for most gear. Please read on.
Consignments can go 1 of 3 ways with us with little leeway
1. Owner pays us for repair work at normal rate and schedule and then asks us to sell the item on their behalf. We charge 10% of net sale amount and buyer receives the remainder. This is paid out as soon as new owner receives and accepts the machine. This 10% covers our efforts to resell and warranty transfer to new owner.
2. Owner does not pay us for our repair at all. We repair and resell the gear at our own cost and schedule and receive 25% of the *gross* sale amount. This covers our efforts in repair and risks associated with the repair process, parts that may be needed/added, and of course performing work without immediate compensation.
3. The “all I need is $X” scenario. This has historically worked well for both parties, in which the owner states a price they wish to achieve, and anything above it we keep. This works especially well for rarer (more expensive) pieces in need or moderate repair work that we may not want to purchase and the owner may not want to pay to repair.
If you find yourself with a rare and house-priced synthesizer in your possession that you wish to sell, you may stop yourself from following through with selling it after considering the liability and risks associated with high-value sales. We can help!
We can act as a brokering service exclusively for items worth in excess of $40,000. We charge 10% of the net sale amount in either of the 2 following scenarios:
1. Unit is working/previously restored by us or other reputable shop and we are brokering/advertising the sale while also offering the following service: technical and physical appraisal and certification of what is being sold. This helps the prospective buyer feel more comfortable making a sizable purchase.
2. Unit is -not- working/not restored. Two separate prices are then drawn up, a sale price and a restoration price (or price range). The buyer has the advantage of buying from a reputable dealer (us) and confident in the restoration process (also by us). We charge 10% of sale price and of course keep 100% of restoration fees.
We have experiencing brokering single item sales in excess of $100,000. Rest assured Rosen Sound / Rob’s Rare Synths is your most fruitful option for selling high end, rare and expensive synthesizers.

Due to the COVID-19 Pandemic, our shipments may be marginally delayed depending on the type of shipping available. We are -not- going to any traditional shipping offices in person to drop off packages. We rely on the near-daily drop offs we get to our shop so we can simply send packages out with the drivers. If you use our air-cargo option, there is no delay however please note your local air cargo office may have earlier closing times/closed on weekends due to the pandemic.
We are offering free CONUS shipping for all synths via air cargo until 2021!
We ship using a few different methods. Our preferred method is via air cargo which is strikingly inexpensive and arrives to you the same or next day, and allows the buyer to pay for the shipping charges instead of it being middle-man’d through us. We stress that the cost of shipping same/next day via this method is exceptionally safer due to the shorter handling times, and surprisingly cost much much less than traditional shipping… and you get your synth faster!
We also will ship UPS if going to the airport is not an option or you prefer it. We know everyone has their opinion on UPS/FEDEX, so we should note that we are UPS people. They haven’t done us wrong.
Want it to ship in a brand new hard case? We work with an awesome local flight case maker who’s been in the biz forever. The prices are reasonable and he has measurements for the most common gear we sell. A new hard case will run $2-600 generally and be ready within a week or two. Note that this service is only offered to those who are purchasing gear from us or repair clients.
