Sunn Amp Serial Number Lookup

SUNN Model T serial numbers quest. However all they can tell you for certain is the very oldest model year the amp. Along with no discernable serial number. Marvin Kay's Music in Jacksonville FL was the first place I saw these amps. They were being eyed by the Rolling Stones that day as they walked through the.

Pretty much any old SUNN amp is worth it. At that price and if doesn't need much work, he probably doesn't know the true value of these babies. Tell you what else is nice and starting to go up in value. Old Sano amps. Awesome, similiar in Ampeg sound (they were actually made down the road from ampeg.

I'm looking to pick up a used one, and occassionally I see both on eBay. From what I know both are PCB based, so I can't imagine a huge difference.

Never played one, but I love what I hear via clips and such. I just need a nice dirty small combo amp that has a decent clean sound.this should fit the bill. Deacon Blues Contributing Member With big iron in his hip. Apr 17th, 2012 06:32 PM This was never a Custom shop amp. It was designed by Bruce Zinsky when he was part of the Custom Shop and produced on the regular production line.

TWhite United States Apr 18th, 2012 06:18 AM According to Wikipedia the first run (I have one) was produced in the Custom Shop. Grey Goose Contributing Member ***** USA/MN Apr 18th, 2012 07:52 AM I had one of the newer ones for a little while. I know that some of the issues (I don't remember what they were) that I read about in the Prosonic thread, I never had.

Newer isn't always better, but sometimes issues get worked out. I did enjoy this amp a lot. I don't know that I would pay more for any one version of this amp and I would buy any version of it. Best of luck! Contributing Member **** Pitt Meadows, BC Dumble is King Apr 18th, 2012 10:20 AM Reported MANY times that this amp (and the Custom Vibrolux Reverb) were Bruce Zinky design amps when he worked for the Fender Custom Shop. BOTH amps were NEVER built in the Custom Shop and were ALWAYS regular production amnps. Wikipedia's post is erroneous.

They are obviously misinformed in this instance.:) TWhite United States Apr 19th, 2012 07:28 AM The first Custom Shop run of these amps have a different serial number which means they were produced at the Custom Shop facility. The true Custom Amp Shop Prosonics are hard to come. You know you have a Custom Shop Prosonic if it has four things. 1) Says 'Fender Musical Instruments' under the jewel light. 2) 'Fender Custom Amp Shop' at the bottom of the tube diagram in the back of the amp. 3) The serial number that starts with LO instead of CR.

(Note: Some of the early Corona models had LO serial numbers) 4) The jewel light is Green. (most Professional Tube Series had a red jewel unless changed) (This message was last edited by TWhite at 07:49 AM, Apr 19th, 2012) Contributing Member **** Pitt Meadows, BC Dumble is King Apr 20th, 2012 01:16 AM 'The first Custom Shop run of these amps have a different serial number which means they were produced at the Custom Shop facility.' The first Prosonic amps were produced at the old Sunn Amp manufacturing facilities in Lake Oswega, Oregan, (after Fender purchased Sunn), thus the reason the serial numbers start with LO. The first Prosonics were made in 1996. The Fender Custom Shop was started in the original Fender facility in Fullerton California in 1987 (guitars only) and was moved to Scottsdale, Arizona in 1991.

(guitars only) It was then moved to Corona, California in 1998. The subsequent Prosonics were then made in the Corona facility as REGULAR PRODUCTION AMPS, thus the reason the serial numbers start with CR. Some of the first Corona Prosonics did in fact have serial numbers that started with LO as there was a 'crossover' (with parts, etc.,) from the Lake Oswega facility to the new Corona facility. Again for the record. Although the Lake Oswega Prosonics (LO) may differ slightly in construction or layout from the Corona (CO) Prosonics, AT NO TIME was any Prosonic ever built in the Fender designated Custom Shop at Fullerton California, Scottsdale Arizona or Corona California. The Lake Oswega faciltiy was NEVER considered a Fender Custom Shop. It was simply the old Sunn factory that Fender used to reintroduce themselves into the amp market.:) TWhite United States Apr 20th, 2012 07:06 AM Then why does my amp say Fender Custom Shop on the rear tube chart?

I know where the amp was built but Fender chose to designate the first run as Custom Shop amps. Contributing Member *** Walton County, GA. We Fixee good, you like!

Apr 20th, 2012 08:34 AM As a full line Fender dealer during the 90's I don't recall the Prosonic ever being ordered as a Custom Shop product such as the Dual Professional,Tone-Master and Vibro King were. I recall them being part of the Professional Tube Series of amps. I know it can really get confusing though.

Because their origin was in fact in the Fender Custom Shop as that's where their designer, Bruce Zinky, worked at the time of their inception. The design was Custom Shop, the production was ALWAYS considered regular production line though.

Interestingly enough, Fender didn't even really have a designated amp Custom Shop at the time, that's why they used the old Sunn facility to start building amps again after the company was purchsed from CBS by Bill Schultz and a group of long time Fender employees. The Custom Vibrolux Reverb 2 x 10 amp (still made today) was another confusing amp as everybody thought it was a 'Custom Shop' amp as well due to the word 'Custom' in it's title. This was another Bruce Zinky design that came out of the Fender Custom Shop (simply because that's where Bruce Zinky worked at the time) but was always a regular production line amp. Fender seems to do this from time to time with many of their products. The Baja Tele's and Strat's were another example. Custom Shop Design. Regular production run in Mexico though to keep them at a saleable price point.:) Contributing Member *** Walton County, GA.

We Fixee good, you like! Apr 20th, 2012 11:02 AM Right you are sir.and on the button. W TWhite United States Apr 20th, 2012 11:20 AM That's good info to have. So if you had an early run Prosonic 'Custom Shop' amp how would you advertise it if you were selling it? I'm not selling mine by the way.

So if you had an early run Prosonic 'Custom Shop' amp how would you advertise it if you were selling it? I'm not selling mine by the way.' I would simply advertise it as that. An early run regular production (LO) Prosonic that was built at the old Sunn manufacturing plant in Lake Oswega, Oregan.

I'm sure some would find that more appealing (and possibly more collectable) than a regular production run (CO) Corona Prosonic. I would also (if possible) include pictures of the chassis and wiring so people can be their own judge as to how they differ (if they do) from the Corona (CO) Prosonics. Side by side photos of an LO run chassis and a CO run chassis would be the ideal. Maybe the LO run Prosonics do have some special mojo over the CO run Prosonics. A blind side by side comparison is the only real way to tell and even that can be subjective at times. Your amp is certainly unique.

I will give you that.:) StratmanMDA Contributing Member Silicon Valley - USA Rock until you can't. Apr 21st, 2012 08:09 AM Super, thanks for the explanation.

I am going to schedule a try-out with someone who has one for sale. Really interested in this amp. Deacon Blues Contributing Member Stay interesting my friends. Apr 21st, 2012 08:31 AM The lead player in our band has one of the old Surf Green Pro Sonics. I gave it a cleaning and tune-up not long ago. Great sounding amp.

Contributing Member **** Pitt Meadows, BC Dumble is King Apr 21st, 2012 09:44 AM I've always liked the Prosonic Amps as well. Dairantou Smash Bros Dx Iso File. Lot's of options that yielded some GREAT tones once one spent some time with the amp.:) / / Reply to this Topic Display my email address Your Message: Link Address (URL): Link Title: Moderators: FDP, LLC Privacy Policy: Your real name, username, and email are held in confidence and not disclosed to any third parties, sold, or used for anything other than FDP Forum registration unless you specifically authorize disclosure.
