I originally used Vinyl Carvers on 10" but found the grooves pretty shallow & volume a bit low however the sound was good with nice bass. Anyone able to report on Dubstudios plates?
I've used Transition and Dubstudio, I prefered Dubstudio but it's a very different sound. Dubstudio is vinyl dubs, not acetates, so if you want your records to smell wierd you cant!
I thought dubstudio did acetates aswell?
Hi sorry my wording was misleading, the dubs I got cut at Dubstudio were vinyl, so it's not an entirely fair comparison is what I was saying!

The theory behind half-speed and the reason for doing it is that you cut the high frequencies and speed in half which theoretically allows more "resolution" in the groove at the high end. It also reduces the power required from the recording amplifier.
Cutting a disk at 45 RPM instead of 33 helps with the high end response since it's more "spread out" (so to speak) at the higher speed, and also tends to reduce tracing distortion to some extent. Gives the overall disk more "sparkle". Same reason in the days of radio transcriptions the disks cut at 33 RPM were 16 inches in diameter and the engineers only cut down to about 8 or 9 inch diameters leaving a lot of blank space at the center of the recording. With the limited recording heads and electronics of the day, this practice helped make recordings that sounded better than standard commercial records of the time. Then Presto came out with the diameter equalizer which solved the response problem... partially.

The recording curve is there to allow more time on the disc. Bass frequencies are very long/fat waves, soo you need to lower the volume of the bass to fit music on the plate. Volume = Time, Louder = Less..
even more, the riaa characteristic is necessary to be able to cut music on a vinyl record anyway...you need to quite boost the high frequencies for them not to fade in the background noise of the record, and you need to cut the low end to get space on the record - but not TOO much, otherwise you would hear the rumbling of the head /tonearm combination of your player, because the phono input in your amplifier or mixer is doing this riaa filtering in reverse...it´s all about dancing on the blade of geometry, as vinyl production and usage is in many ways....
i have done sae and wrote my paper about vinyl cutting, never did i get my hands on it unfortunately..
great thread, big up to jaybirb, j & all the cutters in here

Don't recall if I posted that I also have a cutting/mastering operation... been a while since I've checked back to this thread.
Amps are original rebuilt Westrex 1574's; after the rebuild with all new passive components the response tops out at over 60kHz (was told 70 kHz by the service shop in L.A. that worked on a problem with one of the choke coils). Cutting heads are newly re-wound and serviced. Have customers in US, Canada, Australia, New Zealand, UK, and Spain. Hit me up or check out

Actually since Paul Whiteman and Rudy Vallee, zero. In the late '20's following the introduction of electric recording they had systems for recording airchecks that 'embossed' an uncoated polished aluminum blank. Sound quality was really pretty good for the time. In 1934 Presto Recording introduced the lacquer "dub" disk and the rest is history.

You just unify the "hot" left/right in series or parallel depending what type of groove you want to be sensitive to. Here's a diagram:
