The RS inventory list is ever changing! As a matter of fact, some synths never have a chance to be listed here as they're purchased before that is possible.
By signing up for our weekly newsletter, you will get the first peek at whats here and what's coming.
We generally send our newsletter every Thursday morning and then post our "sales drop" via Instagram stories in the afternoon.

Current Inventory

Updated 4/21/25
If you are interested in anything below, please send us an email or give us a call.
Most items have an estimated lead time that can be affected by the number of orders we receive at once.
Once something sells, we will mark it here SOLD immediately until the next update cycle.
Prices are generally firm but we will happily give you a great package deal if you buy more than one synthesizer.
Prices are either same or slightly lower here than we would list on reverb when accounting for their hefty fees.
If you "saw it on reverb", let us know and we'll happily work out a mutually advantageous price!

Payment:
We accept PayPal, Wire Transfer, Zelle, Credit Card, and of course Cash.
We accept Venmo for items less than $6,000 or so.
Our #1 priority in getting paid is avoiding fees. Your offer will be the most attractive if it avoids fees.
Deposits: We accept deposits on any synth over $15,000. Our deposits are usually 90% of the total price.
We do not accept deposits on negotiated prices.

Shipping

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 are currently offering free shipping in CONUS if you utilize air cargo.

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.

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 $3-800 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.
