Solid State Guitar Amp Forum | DIY Guitar Amplifiers

I am tracking down information on the Peavey Musician amp 400 series. I bought one new with the Peavey 410 cabinet around March 1974 and used it until June 1977 when I sold it. It was too loud (140ish watts into a 4 ohm load) and I was tired of hauling it up to our 2nd floor apartment.

I decided to track one down and use it in my studio.  I plan to make a couple of mods to the amps.  To my surprise, there are three versions of this amp.

Version 1 (Mark I)

This one does not have the Master Gain/Reverb knobs. It does not have Parallel/Serial inputs.

The foot switch has a DIN 3 pin plug. Per the schematic, the foot switch has three foot switches.  It appears in the Peavey 1973 catalog. 

Peavey refers to the Mark I as "A Series". This label is found on the amp schematic.

The user manual is on the Peavey website, Archived Manuals, under the M section as "Musician".


Version 2 (Mark II)

This one DOES have the Master Gain/Reverb knobs. It DOES have the Parallel/Serial inputs.

The foot switch uses a 7 pin DIN plug and it has 5 foot switches. Peavey refers to the Mark II as "B Series". This label is found on the amp schematic.  The user manual is NOT on the Peavey website.


Version 3 (Mark III)

The Mark III Musician has the Peavey Mark III series design:

I do not know what kind of foot switch it uses. All the manual says is that it uses a "DIN" plug.

The user manual is on the Peavey website, Archived Manuals, M, as "Mark III Series Musician".

1.  Where should I put an Effects Loop connectors for the Mk II model? The schematic is HERE (http://www.oresteen.com/images/Amps/peavey/musician_b.pdf) .

2.  What is the best place to put a master volume control for the Mark I model?  The schematic is HERE (http://www.oresteen.com/images/Amps/peavey/musician_a.pdf)

3.  Does anyone have the user manual for the Mark II Musician?

4.  Does anyone know the dates of introduction for any of the Musician models?


Thanks!
