here's a pic of my favorite amplifier, the 1969 Vox Series 90,
(identical to a Vox Royal Guardsman, but the Series 90 is
150 watts, has a Midax horn, and the Head is now a Preamp,
the amplifier itself is now inside the speaker cabinet.)
This amplifier sounds beautiful and rich.

I also have a re-issue (1999) Ampeg Reverb Rocket 212R.
True to the original (I had one in 1965), it is a screamer,
but lacks the sound quality of the Vox.

here's the C200 box from August 1979.

No schematics, only the User Manual and Warranty Card. The opposite flap of the box has the serial number of my vol/wah.

you're welcome!

before the Mutron III Envelope Filter, there was the Funk Machine Envelope Filter.

it produces a "awh-awh" sound instead of a "wah-wah" sound.

mine is from 1968. made by Seamoon, they invented the Envelope Filter.

To Ceasar what is Ceasar's.

and then came MXR and made history.

Here's one of their last products, the OMNI 180.
A rack mount effects unit with Compressor, Distortion, Active EQ, Delay,
Flanger, Chorus, and the ability to connect the Mutron Volume Wah pedal.
All controlled from floor switches with LEDs.

mine is from 1983, the year it made its debut as a factory demonstrator
used at the 1983 NAMM Show in Atlanta Georgia. I was lucky that I knew
one of MXR's engineers, and after the show, I bought it. (very low Serial Number).
(NAMM = North American Music Merchants Show).

I have kept it pristine, in the original box, with User Manual.

Enjoy! :welcome

Interesting. There was an Ibanez rack mount multieffect similar to that. I can't recall the model name, but i think it was very similar. Each effect (+ an external insert) had an "instapatch posititon" switch that allow the user to set quickly the place of every effect in the chain.

yes, I remember them from around 1985.

The Omni has the same option but you push different buttons instead, to set the order of the effects that are "orderable", since there are a few like Compression that need to be at the top of the chain as the User Manual explains. for example, you would not want the Compressor at the END of the chain due to issues of GAIN and other reasons.

It is my demmo, and mine converse... :blackeye .
enclosure was originally some kind of old volume pedal.....friend give it to me....
LDR3 is there to help adjusting how LED is going to react..to calibrate led/ldr combo(it must be close to LED)....I made little modification of circuit....added one more LDR and switch so I can get MutronIII topology also.........

cheers
